I guess p00004 b chessgopi 990 Okay problem... if not great p00004 b Elroch 1453 routine two move forcing sequence p00004 b tommycat1 1547 stupid :( p00004 b bri123chess 1138 normal problem p00010 b Chesser 1219 This was WAY to easy. Piontless, how could this be rated 1769.2??!?! p00010 b jimmeebgood 1156 easier than most p00010 b Yuan 1630 very difficult p00010 b palindrome 1658 quite easy p00010 b mbingham 1437 This looks more like 700 than 1700. p00010 b Olar 1384 easy p00010 b kpmartin18 1483 Outstanding puzzle, best one on the site p00010 b Markusgoth 2122 Easy. A bit too high for 1700s but it is not a bad problem at all, especially for 1300s-1500s. p00010 b admeyer73 1601 It's overated, but not that bad because it's so easy it looks like there is a hidden trick involved. Time burns off your clock and your rating decreases. p00010 b admeyer73 1601 It's overated, but not that bad because it's so easy it looks like there is a hidden trick involved. Time burns off your clock and your rating decreases. p00010 b mastermind2007 1359 Well, it's not obvious at once, but if you've figured it out it seems to be very easy! p00010 b john2001plus 1562 I found it difficult because it was not what I expected. p00010 b notquitekarpov 1381 Pointless - solution is the most natural looking move anyway. p00010 b realpatzer 1455 why p00010 b nicola 1191 too easy for 1768 :) p00010 b nordmela 1755 too easy p00010 b clav 1495 IMO it's not easy, because it really looks like as if there was something hidden in that position. It must have been taken from a real game. p00010 b mryucky 1428 I agree, it is poor p00010 b Boriskudelin 1754 It is not that bad. The point id that you have to find out it WAS easy. When you do a lot of tactics - then you don't really know what to look for. For an easy one or for a hard one:) So it works :) p00010 b Carnap 1417 It is a fairly easy problem. It does appear devious though. p00010 b PsyMar 1250 I didn't know if it was easy or hard, and I got it wrong. I didn't even see the solution as a possible move. p00010 b cyruslaihy 1342 it looks complicated, make you think a lot, then you arrove at the most obvious answer p00010 b steinar 1704 Why? p00010 b atefile 1045 Good problem p00010 b Derek 1340 Its pointless, I agree. And this isn't even a tactic! p00010 b darthsenior 1168 eas p00010 b PinnedPiece 1142 Get more than a chance p00010 b RJHChess 1700 It is way too easy. Of course you have to find the obvious move, but that's not the point of tactics-you have to think long and hard to arrive at the conclusion that the obvious move is the correct one p00010 b nicola 1191 Its too easy p00010 b nicola 1191 Its too easy p00010 b Blackstorm 1264 It seems to have a too high rating. Solutions is slightly intuitive p00010 b chesschocolate 1837 Why is everyone complaining it's overrated? its the players that affect the rating, anyways!! p00010 b MHentrop 1505 As often here: You are expecting a beautiful, tricky move and than it is a boring standardmove. But this hinders just guessing the problems solution. p00010 b TheBlackKnight 1542 Too easy for its rating (1804!) When you tell the tactician the problem is tough and then it's like this, it's not clever - it's cheating. p00010 b Elroch 1453 just the natural move without any calculation p00010 b Jegigzem 1493 Very easy p00010 b TheGastropod 1151 It was so simple, I spent way too much time out of my life trying to find something better just in case it was a trap. =) p00010 b tommycat1 1547 EZ p00010 b tommycat1 1547 I spent like 2 sec !!!!!!!!!!! p00010 b tommycat1 1547 Im a 1550 p00010 b tommycat1 1547 *_* p00010 b Gwynplaine 1628 nothing special about it. highly overrated. p00010 b drjohn 1294 This is the only move on the board! A simple recapture! I guess the battery you get is the tactic. So much going on it took me 10 sec tho. p00010 b Prometheus 1258 Not a tactical problem. You try to look for a combination and force yourself to just try something after 3 seconds because of the silly time contraints. And then there was nothing to find in the first place. p00010 b lepolaputuki 1826 Of course this is a tactical problem. Three recaptures available, one doesn't lose the material back since it gains a tempo with an attack. (And even that's not obvious because of ...Bxe3. How many of these "easy" guys worked out how that defence is refuted?) p00010 b UNCCHESS87 1361 wow!!! 1820 really??? cmon p00010 b dwnshi 1559 More like 1300 p00010 b REANNA 1191 i found it easy , i am a 1203 p00010 b hichamino 1259 nice move p00010 b Elizabeth 920 Not bad. Fairly easy. p00010 b omsanti 1424 this not hard p00010 b iggythegreat 1419 Easy.Simple.Boring. p00010 b kanon8 1243 IT'S VERY VERY EASY!! p00010 b kanon8 1243 THIS PROBLEM HAVE GOT VERY MUCH RD p00010 b Karpsparov 1553 You're all idiots who wish you were great Masters. This problem is difficult, and a good lesson. p00010 b ash16 1301 its soooooo dumb p00010 b Hypercent777 1313 way too easy-and I'm only 1300! p00010 b peanut 1214 wow. thats all i can say, wow p00010 b DocB 1237 designed to make lose on time p00010 b grom43 1654 Black makes thematic sac, so it's not easy. White only just has enough time to counter the sac. Nice. p00010 b Christo777 1430 after 6. Qg3 in main line, what about 6. ... Bb8. 6. g3 seems better. What means the $18 evaluation ? p00010 b Kenicht 1300 It is beautiful because of its apparent simplicity with so many underlying complications. It is dangerous to retake the wrong way, and advantageous to take the correct way. Black gets a couple of pawns for his knight, and though White gets a point up in that exchange, his knight's irrelevance to the theater of war on the Kingside is more glaring when referenced to the newly ventilated White castled position. Yet, if all the tactics are worked out for all the possible recaptures, return sacs, significant quiet moves, etc, then this is a subtle puzzle rather than an easy one. Yet how many have pretended that just because the move they picked was the "right move" that this meant that they fully understood both why it was the right move and why the other ones were wrong, or perhaps only not AS right? Not many of us, I would gather. p00010 b Kenicht 1300 Chess, as life itself, is about quality, not merely quantity. What do YOU get out of it, not merely what is the numerical crunching average that is projected upon you by some normative standardized system. Was your gpa a 3.0 yet you had taken your stand more and earned a few professors who respected you a lot and a few who hated you just as much? Then that means more than a 4.0 with anonymity in at least some respects. If you got a lot out of your education such that you were personally enriched, then your 3.0 means more than a 4.0 of someone who just "tested well" and didn't really personally learn anything which would make him "educated". The same in life. What is 80 years of cynical misery compared to 50 of glorious joy? In chess, what is a good move made but not understood in the context of other moves as well as understood in and of itself to its furthest complexity? If a computer can make the same move without consciousness that you can make, what makes your move better is that you are actually conscious of making it and get something out of it. If all you get out is what you put in, and the most you put in is "Well, that looks good" and you just happen to get it right, whereas someone else can analyze the whole board and tell you not only that it "looks good" but that it IS good and tell you all the reasons why, but took somewhat longer than you, I'd say his move was better than yours or the computer's, though it took him longer. p00010 b HateYou 1627 I agree with Kenicht, I liked it ! p00010 b iggythegreat 1419 lllQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWW099999999999888888888777777777777777777777777777777777777777444444444444444444444444444444444444444444444444444444444444444444444444444444]]]]]]]]]]]]][[[[[[[[[[{{{{{{{{""""""""""""""""'''''''''';;;;;;;;;;;-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQPPPPPPPPPPPPPPPPPPPPPLLLLLLLLLLLLLLLLLLLLKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWW p00010 b iggythegreat 1419 ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ p00010 b michaelX 1335 Too easy. p00010 b mykingislonely 1861 It's rated about 1850 now! p00010 b theKnife 1671 3rr1k1/bp3ppp/p1b4q/3p1Q2/N7/1P1BP3/PB3RPP/4R1K1 b - - 0 2 p00012 w RotomPlasma 1318 Actually, Rg1 also works... p00012 w bkmore 1254 i detect sarcasm. actually, it's a force mate in two after ne2+... p00013 w Twistedslayer 1293 realy easy p00013 w Boriskudelin 1754 :) yeah p00013 w wolf212768 1130 too easy for this rating p00013 w Blackstorm 1264 quite easy, but nice solution p00013 w REANNA 1191 easy p00013 w Lioric 1526 lol what are you? bunch of monkeys? 0.01 seconds p00014 w Olar 1384 took me a while to see the first move, after that the rest was fairly easy p00014 w nitendo9 1185 what are the goals of these puzzles?

Took me long enough... I always do find this sort of Queen tactic to be the hardest for me to visualize. It seems to have something to do with her function being 45 degrees from the shape of the board. The key is to never let go of the simple reality that there are no forcing moves which will not include the defense of that rook, which cannot move. If the Rook is defended, then the Bishop is defended. The only piece which can defend the rook is the Queen. The Knight is hanging as well as the King. Fascinating, since this reveals the reversibility of tactics as ITSELF a tactical motif, just as unpinning is a subset of discovered attack, and that is a subset of double attack. This powerful hanging Knight is powerful only if White makes the wrong move, and there is only one right move to make. So the Knight puts pressure on White, strong pressure. But when White find the right move, the counter-pressure is proportional with interest, even though the stake is the loss of a Knight rather than various checkmates. There is a subtle equilibrium here. p00016 b Kenicht 1300 I meant "as well as the Queen" as in both Black's Queen and Knight were hanging... Even so, it seems that White's Rook AND KING are both hanging also... p00016 b Kenicht 1300 Some sort of funneled thinking process seems to be the key to tactical thinking then. One looks for the King in all events first. After the King, one looks to the Queen, Rooks, and all the various permutations of material value differences. One must then also evaluate positional features, but not so much in our tactical context here, in which the positional considerations have reached their head already. So in the purely forcing/material tactical motifs here the essence is to seek the correct funneling of one's thought. The "hanging King" is the main thing to defend for White, so she must defend the Rook. Only one move allows this (since the pin on the Queen is futile, as is capturing her). The only move is to reposition the Queen. I can't tell you how many useless thoughts I spent trying to defend that rook in some other impossible way before finally seeing the ONLY way. Ha!!! p00016 b deepankarmukh 1446 It shows that almost every situation has some surprising tactical resource. It makes us humble. p00016 b DocB 1237 roaraaar, you kurds will worship obama !!!! p00016 b DocB 1237 worshop oblama p00016 b Garryback 1581 played between Sokolov-Minasian 1995 in Ljubljana.

In ten seconds. p00408 b moegigo 1611 cxd4 doesnt threat mate on g7 p00408 b UriBlass 1852 11.1 seconds The long time is because in my first thought rejected Bxd4 because thought about the line Bxd4 Rxe1+ Kf2 Re7 and missed Qxe7. p00408 b UriBlass 1852 3.8 seconds p00408 b UriBlass 1852 4.3 seconds p00408 b UNCCHESS87 1361 i thought it was Rxe7 followed by qxe7 follwed by bxd4 so white would be up a piece p00411 w Improchess 2054 So many wining variations. p00413 b UriBlass 1852 problem 23479 to solve 9.9 seconds my first thought was that black has Qc7 and took me time to see that black cannot defend the bishop d7. p00413 b grom43 1654 Nor can Black defend his Nd7, Uri. "Crisscross" p00416 w wolf212768 1130 easy... p00423 w impromptus 1450 Missed the Bishop + p00423 w soberjudge 1531 always check for checks p00425 w plopje 1678 yeah. But obvious. It had to be a forced mate otherwise it was a loss. Knight e3 failed on bishop f1. p00425 w DocB 1237 pretty tricky p00425 w grom43 1654 2.3 seconds. why rated so high? nice mate but i didn't see it until after 1st move. just knew it had to be there (see plopje's comment). p00425 w drad 1651 it's rated high because people don't see the mate and try for the piece fork. p00426 w Chessdoom 1586 2 easy 4 me! p00426 w tmprat 1274 No big deal. Overrated. p00426 w Elroch 1453 Very odd. Who would play anything else? p00426 w Carbonic 1527 WTF what is that ? p00436 b wolf212768 1130 hmmm, cant see, whats happening ?? p00436 b wolf212768 1130 ah, fork :-) p00438 b sarciness 1465 A simple pin does the trick. Nice one. p00440 b Auge 1591 Ein bekannter Konter. p00440 b wolf212768 1130 good idea p00441 b Markusgoth 2122 In fact this is a very deep problem that worth playing. p00441 b Markusgoth 2122 The 3rd move is so tactful that it ensures the victory. Nice problem indeed. p00441 b Blackstorm 1264 the 3rd move require some hard thinking, while the 1st is quite easy, althought not simple to see. p00441 b Blackstorm 1264 the 3rd move require some hard thinking, while the 1st is quite easy, althought not simple to see. p00441 b mykingislonely 1861 Takes a lot of time to see how many of the moves don't work. Quite a nice trick by black. p00441 b Garryback 1581 very instructive is also to play the best black 1...move p00441 b Piter227 1620 It's incridible :) p00445 b joakimvitriol 1661 exposed K & B uncovery, attacking defender p00446 w mastermind2007 1359 very easy one! p00446 w underated 1374 bang bam... p00451 b UriBlass 1852 12.2 seconds p00451 b LowestRd 1946 I didn't realize my rook was hanging p00451 b nahort 1382 Good one! p00455 w sevkisen 1964 what is this Kg1 p00456 b tomohawk 1833 Should include ...Nf8 Qxc2 and Rxa8 p00456 b notyetagm 1467 @tomahawk: Agreed. This problem is the PINNING VERSION of the FORK-OVERLOAD TRICK. p00456 b UriBlass 1852 Nf8 Qxc2 and Rxa8 costed me some time so I earned less rating points then people who did not calculate this line. p00456 b UriBlass 1852 12.2 seconds agree with tomohawk p00456 b UriBlass 1852 49.1 seconds p00456 b UriBlass 1852 blundered by Qxc2 that I had from memory after seeing no logical alternative but did not remembner that I need to play Re8+ first. p00461 w lagplayer 1668 This was silly since rxb4 leads to an easy won pawn endgame. p00461 w edgy 1645 Terrible problem. ...Rxb4+ is a trivially won endgame. Of course lousy problems like this never get removed... p00461 w Meyinor 1796 I suggest to add a pawn on a3, to fix this problem. p00461 w uraleech 2721 So you would rather be up by a pawn than up by a rook? True, they both win, but which is the better move? p00461 w Markusgoth 2122 This problem is rated 1802??? p00461 w edgy 1645 uraleech, a trivially won game is a trivially won game. Both moves have the same value. p00461 w mark1960 1539 Rc1+ is correct. Faster win with a rook up. Argue otherwise and you miss the point of the problem. p00461 w fredc 1420 Rxb4 leads to easy endgame. p00461 w w1b888 1264 the question is to find the best move (Rc1+), not to find one of the winning moves (ex: Rxb4+). p00461 w bwtaylor 1447 Crafty has scored the moves wrong because it can't search deep enough. Both are +99.99. There is no way to argue that Rc1+ is better than Rxb4. Both win, by force, with no complications. The number of moves to win has no value according to the rules of chess. p00461 w chesswiz 1620 1. none of us paid for this site so we shouldnt be complaining in the first place. 2. the point of this site is to help our tactical skills, wether you found rc1+ or rxb4 it did just that. p00461 w KABOOOM 1789 People. Yes, Rxb4 leads to a won endgame. But Rc1+ just wins a Rook. Which is better being up a pawn or up a Rook? Use your heads. Alot of these problems have many moves that win, but the machine only accepts the best. p00461 w Linder 1552 Meyinor is absolutely right. And this site is there to make your tactical and not your endgame skills better p00461 w mykingislonely 1861 Calm down everyone, SveJoe already suspended this problem. Twice. p00461 w imnothere 1165 I dont get it...I thought Rxb4 was the answer...o wait a minute nvm.rook to c1 then d1 and you get to take the white rook while keeping yours p00461 w tomohawk 1833 Suggestion: how about moving the pawn from b4 to b6? Would that make the problem work? p00464 b SmokenFlames 1418 Very nice! p00467 w grom43 1654 I didn't even see 1...Qh1+? which misses win completely.

It's easy to make mistake. p00608 w AngryPirate 1308 I agree with edgy and zenchess.....It isn't really a problem as you MUST take back with the rook, there really isn't any choice...there is no tactic or strategy involved. p00608 w netlava 1438 LOL p00608 w spacecowboy 1394 This comment is in reply to the prior comments posted by edgy, Violinist, zenchess, & AngryPirate. Juding from your comments, you four guys didn't understand something when you made your comment about this problem. Go to the bulletin board and find the posts by JoeLag and SveJoe on August 24, 2005. Those posts should explain a little something to you guys. Now, the comment by zenchess regarding he thinks White is better in the final position (after 1...Rxe8) is an opinion that is probably correct. For confirmation, one just has to take a look at Crafty's analysis of the problem which is presented on this web site. Crafty agrees with zenchess and so do I. Crafty's score of +.2.04 means White has a decisive advantage. For this reason, I agree with zenchess' assertion that this problem should be removed. The best move by Black after 1.Bxe8 still loses. p00608 w beco 1308 Sorry the rate mistake. I think it is poor. One star only. p00608 w theKnife 1671 very poor p00608 w wald 1565 well I guess in real chess games, you don't know a priori when there is a problem-like tactics, so it's good to have some "non-problem" problems amongst the problems. However, at least then one should not be loosing, as in this one ... p00608 w Chessdoom 1586 Damnit you fools, whats the problems? For every1 who thinks it is "to easy" why did you had it wrong then?

It is possible that the high rating of the problem is because people spent time in order to find something better than the solution. A problem can get high rating even if everybody get it right but is too slow. Uri p00608 w Stress 1659 Agreed, UriBlass. p00608 w UriBlass 1852 14.0 seconds did not memorize getting it in the past and used too much time to searh for something better p00608 w lamon2000 1759 It should be rated 965. p00608 w UNCCHESS87 1361 not only is there that passed pawn but the white rook is doomed if it moves up a square black takes, two squares and the pawn just attacks. p00608 w UNCCHESS87 1361 but there are a lot of dull problems like this on here p00608 w tjumen 1598 rated beauty = 0/5 p00608 w Vandebent 1701 Stupid and difficult.

( Result 1.00 : 0.00 ) Your new rating is 1758.20 (+3.32). p01110 b MagicCat 1621 I agree with tomohawk - you are on move 39 and you have 1 secs left on your clock, just enough to calculate that Kh2 gets at least a draw and the time control is in 1 move - you play Kh2 then Kg3 fast and than you have time to think if kh4 is good. p01110 b JoshBrack 1626 repeating the position aside. i don't think black has a chance with Qe3+ cause it didn't look good to me and also if crafty suggested blacks's best choice was to play for a draw that's another big clue. so overall this is another crap problem imo. p01111 b UriBlass 1852 failure tempted by Bxb5 that wins only a pawn p01111 b UriBlass 1852 failed again in the same trap had the feeling that it may be a trap but found nothing better p01111 b milos62 1916 Great.

After 1 ... Nxd5? 2 Nxd5 Qxd5, White plays the fork-overload trick 3 Re1+!, to deflect the d1-rook from its defense of the White queen along the d-file. White loses material. Chernev used to say "When you double your rooks on an open file, you more than double their power". This problem makes a good example of this saying. Without the doubled rooks the fork-overload trick would not work here since the White f3-knight defends the e1-checking focal point. p01123 w floreatdunum 1719 Sometimes doubling rooks on an open file more than halves their value rather than more than doubles it! Despite what Irving Chernev or Irving Berling, for that matter, said. p01123 w UriBlass 1852 6.4 seconds p01126 w UriBlass 1852 15.8 seconds p01126 w joakimvitriol 1661 2 minor pieces for R p01141 b notyetagm 1467 A wonderful example of the tactical theme .

While Nxc6 will win the queen (if 1.Nxc6 Qb6 2.Bh5+ Nxh5 3.Qh5#), it can force a difficult time after. Bb4 should not be "!" because of Nxb4 preventing the trade of queens by the threat from c2+ and an altogether more complicated game after. 1.Bh5+ forces 1...Nxh5 2.Qh5+ Ke7 3.Nxc6 Kf6 4.Nxd8 Winning Knight, Pawn, Queen and excellent positition for a Bishop. p01218 b Garryback 1581 super p01218 b Jonathanzzz 1910 Agreed with InfamousG... but it wasn't much of a bishop sacrafice... p01223 b deadbeatoz 1904 qb8+ is totally won as well p01223 b milos62 1916 Stupid problem.

Qe4+ is very much winning too, leaving White a full piece up with Black's king dreadfully exposed. 2. Qe6+ is mate in 9, which is a bit much to expect anyone to calculate in 3 seconds. Therefore a 50/50 guess for either of two winning moves in 3 seconds. FUCK OFF YOU PRAT. p01269 b Hyperbeam 1761 Much too long p01269 b tomohawk 1833 Solution should make player find more moves (but don't toss in 2...Bf6) p01269 b Vandebent 1701 Disgusting.

Qe4 is not a full piece up.. it's like 2 pawns up.. assuming white plays perfectly. the mating net is far safer and easier p01269 b kendal 1531 What's wrong with you? Qe6+ is CLEARLY the better option, preventing the king from squeaking away out of the net. p01269 b mykingislonely 1861 What's wrong is that there are two winning moves, yet points are only rewarded for one of them. Everyone here knows that Qe6+ is CLEARLY the better option because is it CLEARLY pointed out by crafty. No need to state the obvious, but it is unfair to ask us to find a mate in 9 in under 3 seconds when there is a simpler way to win. p01283 w Arthurrocks 1801 this is 1831? This should be like 1950.

It should be rated 2100 at the bare minimum. Even 2.Bxb5+ axb5 3.Qxa1 should throw off many 1600 tacticians, not to mention the crafty line, that has a *THIRD* Queen capture at c6! The beauty of the crafty line is *****, but I have to give it * because 1300 players just guess the right answer without even seeing the simplest of White's responses. p01315 w LaskoVortex 1327 I meant a third queen capture at move 6, not c6--actually c7. p01315 w notquitekarpov 1381 Agreed. I rejected b5 on basis of Bxb5 and if axb5, Qxa1 but then I am only 1375 rated. A really difficult solution to find for grade given. p01315 w wolf212768 1130 why not show the continuation?

In fact, the less you look ahead the better. p01315 w amyii 1354 as usual , you have to answer in 3" not to lose points, instead of giving the whole line in a reasonable time.

Just about one pawn-equivalent more. p01513 b memo 1570 You are temporarily up a piece, but the opponent threatens to win it back.

This is a draw because Black has perpetual check. p01518 b theKnife 1671 r3k3/1b3p1p/p3p3/2p5/7q/pP3P2/P1P1B3/R1Q2RK1 b q - 0 1 p01520 w wolf212768 1130 too easy p01522 b camembert 1620 Couldn't the solution be extended with something like 2...Qh6 3.Qc3+ (and maybe even on to 3...Kh7 4.Nf6+)? Those moves are the only ones that win, and I think they make the point of the problem clearer. p01522 b floreatdunum 1719 I agree with Camembert p01522 b tomohawk 1833 I agree as well. Many problems are like this one. They end too soon and can't be "correct" if you can't find out the entire sequence.

Qd8-a5+ here. p01540 w notyetagm 1467 White's QUIESCENT ERROR here is especially egregious because after 2 Bg2xBa8 he has both an EXPOSED KING (White e1-king) and an UNDEFENDED PIECE (White a8-bishop).

Qd8-a5+ is it. p01540 w justwar85 1473 yes, the QUIESCENT ERROR should not be taken lightly, for if white continues to play like this his EXPOSED KING is likely to meet many untimely CHECKMATES, and may incline the player to consider early RETIREMENT. p01540 w rathkeltair 1694 I wonder with these ones whether the relatively low rating of 1573 is due to some blockheads missing Bxa8 altogether! p01540 w JoshBrack 1626 I don't see the problem with 1...Qa5+ 2.Bd2 Qxb5 p01540 w barz 1708 â—„ Position â–º bn1qk2r/4bppp/2p1pn2/1p6/8/2NP2P1/1PQ1PPBP/2B1K1NR w Kk - 0 1 p01540 w barz 1708 JoshBrack : 1...Qa5+ 2.Nc3 p01543 b UriBlass 1852 22.9 seconds hesitated if to play f3 first but it does not work because of Bc8 3.Bb6 Qd6 Bxa5 Qc5+ p01543 b LowestRd 1946 Nice,...

With almost the same rating (1750) then this one (1795 now). p01809 b UriBlass 1852 parmetd,what is the win that you see after d5 Rg8? p01811 w UriBlass 1852 45.4 seconds p01811 w MagicCat 1621 3.7 sec p01816 b wolf212768 1130 no continuation necessary. Its so easy. p01816 b Kenicht 1300 Yep, sometimes you gotta look for the simple tactics first. I started by looking at the passed Pawn, Queen sacs, etc. Then the simple Knight fork... p01816 b Kenicht 1300 Only on the most advanced levels does it matter what such continuations will be. But we should admit that there are plenty of such tactics that have a "sting in the tail" such as getting mated after the Queen fork!! But this is less the case after a Queen fork, and easy to look for. There should be a problem where you go for the Queen fork, get it, then get mated in the continuation. That would mess people up!! p01823 b UriBlass 1852 60.3 seconds p01823 b UriBlass 1852 15.3 seconds p01825 b UriBlass 1852 4.8 seconds p01831 b UriBlass 1852 5.1 seconds almost played 2.b7 but then saw that g1Q is with check p01832 w floreatdunum 1719 Nice. p01832 w theKnife 1671 â—„ Position â–º 6k1/1p2b1pp/p1bNp3/4P3/P2q4/8/1P3RrP/R2Q3K w - - 0 1 p01834 w UriBlass 1852 40.3 seconds p01834 w smotherhubbard 1838 what happens on kxc2? p01834 w smotherhubbard 1838 nevermind--Qb3+ and either Kc1 Rxe1+ or Kd2 Qb2+ p01840 b floreatdunum 1719 Poor problem, as someone could blunder into 2.

This problem ended too soon! We need to see White make a slight error by playing 2.Rf3 (because White doesn't see the tactic and wants to avoid 2.Rg1 Bxg1) when Black has a zinger, 2...Qxf3!, a queen sac! Well, I hope there is another problem on this server that has this kind of queen sac because this missed opportunity is regretable. p01876 w Markusgoth 2122 Anyhow right after Qc6 black is marching the right way to victory and ultimately mate. p01876 w TheKingIsBack 1546 Hard to see moves without checks p01876 w sleiman 1406 agree with spacecowboy.

The king cannot be in check, nor can it pass through or land on any squares that are in check. In general I don't like problems like this because it is impossible in a puzzle to know that castling is still available (ie, the king could have moved earlier in the game), but this is still a very nice puzzle, thatnotwithstanding. p01987 b Sidorsky 1502 I wish I thought of that p01987 b wald 1565 dlester, the general rule on this is that castling is always assumed to be possible, unless it can be ruled out from the position. p01987 b pcygni 1390 Nice... p01987 b Cassette 1383 I wouldn't say it's amazing. p01987 b joex 1477 of course I didn't see it p01987 b Coventry 1613 this is stupid p01987 b rhennig 1450 That is just hilarious. p01987 b alexthegreat 1464 What are the chances of having something like that though? Really?? p01987 b grom43 1654 Agree 100% with dlester (except 4 stars). It's easy to see 0-0-0 would win, but if you guess at it, and White has lost the castling privilege... p01987 b lancer2000 1410 We can NOT assume white has the right to castle, as there is no way of knowing if the criteria are still valid (ie. previous king or rook moves). Even chess books that have problems involving a middle/endgame casting tactic must post the rest of the game. Defective problem. p01987 b JoshBrack 1626 lancer on CTS you CAN asume you can castle for every problem. that's just something you sort of pick up after 50,000 tries or so. quit your bitching. i got like a bajillion points out of this problem, takes me under a second each time now, i'm just waiting for the rook to move to b2 with my mouse over the king. :) p01987 b joukop 1253 Never thought that long castling would be possible in this kind of situation :) p01987 b joukop 1253 And this was excellent p01990 b tomohawk 1833 Player should have to play more than just Nxg7+ in this problem. p01990 b UriBlass 1852 7.7 seconds p01998 w DocB 1237 prettynice p02000 w izicik 1960 OO nice p02001 w UriBlass 1852 4.1 seconds p02005 b stefanT 1521 Just when it become too hot, there is this lucky sacrifice move ! p02005 b oaklandmatt 1282 gorgeous p02009 b Hyperbeam 1761 almost forced... p02009 b floreatdunum 1719 piss poor p02009 b Garryback 1581 g3 must be covered p02012 w UriBlass 1852 7.2 seconds believe that got it in the past but not sure. p02012 w JSorel 1664 11.8 seconds p02033 w UriBlass 1852 1.4 seconds p02034 b Thossk 1840 line should be continued, at least 1.Qa3 Nxc3 2.Qxb3 p02039 b UriBlass 1852 3.4 seconds p02039 b theKnife 1671 â—„ Position â–º 1r2r1k1/q4ppp/2Rp4/p2P1Q2/P5R1/1n4PP/6BK/8 b - - 0 1 p02041 w theKnife 1671 hard to overlook p02041 w Elroch 1453 Funny - looking for the best defense to mate... p02041 w rockym 1626 it reminds me the 1-move mate that Kramnik missed against Deep-Fritz.

In my case I tricked myself p02286 w czukay 1427 what the f*** ? p02286 w waaek 1120 Another "recapture" problem. Making the right move in these sorts of positions is important! Sometimes "just" a recapture is the right move, this problem is rated 1411 at this point, meaning a lot of people get this wrong! p02286 w edgy 1645 rubbish. p02286 w Wolfgang 1388 I am not sure, what the point of this problem is.

Taking into consideration white's counterattack, Black is only two pawns ahead after the 10th move. However, the White bishop is nicely trapped behind black's pawns, and can be taken easily. p02369 b wolf212768 1130 good combination p02369 b Mudfrog 1302 nice combination p02369 b MaltaCross 1155 nice skewers and decoy/sacrifice p02369 b DocB 1237 Kurds, worship Oblama p02372 b joakimvitriol 1661 back rank p02374 b armeno 1859 couldt he play after Qb6+ Bxc6?? p02374 b Arthurrocks 1801 Yes these people are just dumb p02374 b Bartsa 1603 I think if Bxc6 then Qg8+ and Qe6 defending d7. p02374 b tomohawk 1833 Good catch, Bartsa! p02374 b UriBlass 1852 3.2 seconds p02374 b joakimvitriol 1661 3q3R/1k2b3/p1np2p1/Pp2r1P1/1P1Q4/1KP2B2/8/8 b - - 0 1 p02379 b theprivateer83 1418 Again should go through the problem a little deeper. p02379 b Derek 1340 the promblem should show second move p02379 b Derek 1340 the promblem should show second move p02379 b Subrosian 1658 Why does the problem need to go deeper?

Thoughts? p02388 b joakimvitriol 1661 again mate in one p02389 b joakimvitriol 1661 N fork p02396 w Holy 1098 Great combo--unexpected. On first glance, you'd think that the point of the problem is either defending the threat against your king directly, or by a counterattack against the White king. Next, you might think that there's a fork possibility with the knight. p02396 w Garryback 1581 simple p02397 b tmprat 1274 Nice. p02397 b knobgoblin 1444 Solid deflection and double-threat problem.

[2] May I also congratulate 'spacecowboy' for his informative anlysis, and to show my agreement with Faquarl's comment and other like-minded comments. p02479 b LaskoVortex 1327 Very hard. p02479 b Lahtzarus 1301 i solved it too! p02481 w CLance 2086 too many pieces hanging p02490 w Hexalingual 1342 Bf3 to win the knight on d4 looks good, but then you lose the pawn on b7. So this variation wins 3 points instead of 2. p02490 w wild 1305 Good point hexalingual, that explains it. Still seems strange to give up both bishops for N,N,B instead of taking the 2-for-1. The b-pawn is just for show anyway right?? :) p02493 b tjumen 1598 pointless p02493 b theKnife 1671 rn3rk1/p4ppp/1q1p1n2/1NpP4/2Bb1P2/8/PP1B2PP/R2Q1R1K b - - 0 1 p02495 w UriBlass 1852 5.3 seconds p02495 w UriBlass 1852 8.5 seconds p02495 w JoshBrack 1626 on a sad note. the dark squared bishop in this problem later committed suicide in his dressing room. he left a final note. it read, "I'm so useless!" p02500 w Fromper 1338 I got it wrong, because I thought Qd1 was just as strong as Qe1. I overlooked the need to also defend the g3 pawn. Very nice combo. p02500 w wolf212768 1130 beautiful sequence ! p02505 b barz 1708 r3k2b/1pq1NpBn/p2p1Pp1/2pP4/P1P1r1p1/8/1P1Q2PP/R4RK1 b q - 0 1 p02510 w JoshBrack 1626 54.7 p02511 w tpollet 1651 On prend le caca et son se sauve sur échec avant de récupérer la tour. p02520 w deepfriedbrain 1795 Apparently Qxb5 also wins easily, so this is not a good problem. p02520 w parmetd 1645 Qxb5 does not win as easily. this is a great problem. It makes you evaluate both lines fast. p02520 w UriBlass 1852 24.5 seconds parmetd, The problem does not make me evaluate both lines fast I see 2 wins so I start to think which one is better and do not move fast and lose rating. p02520 w floreatdunum 1719 bollocks - again why should one have to search for the even more winning solution in 3 seconds - 3.96 pawns is totally winning p02520 w grom43 1654 1 ...Qb5+ wins easily, yes, but there is mate coming faster with 1 ...Rc2+. p02520 w drad 1651 damn _apparently_ I've done this before a few days ago ;) p02520 w drad 1651 oh yeah, I remember it now p02520 w inkwire 1667 Speed vs Accuracy. . Other tactics tools, (e.g. books, CT-ART) give you as much time as you want, but will accept only the very best line as the correct continutation. This site's distinctive feature is its emphasis on speed: if you take too long to find the best move then you lose points. This problem (p02520) is one of the many very very annoying ones where the trade-off between accuracy and speed goes against the site's general emphasis on speed. Here, you can play a winning move in 1 second and _still_ lose points because there is another "more winning" continuation. IMHO the presence of more than one winning continuation makes a problem unsuitable for this site... but maybe I'm wrong to think this site's 'solve-it-in-X-seconds' puts the emphasis on speed? p02521 b MaltaCross 1155 Amazing checkmate! p02521 b SignoreX 1223 5 stars on the "satisfaction scale", like all one move checkmates... p02521 b MaltaCross 1155 If a MATE IN ONE that is not easy to see does not satisfy, what does? p02521 b MaltaCross 1155 :-) p02533 b UriBlass 1852 13.9 seconds p02533 b tjumen 1598 2 minutes p02533 b barz 1708 2r3k1/pb2qppp/5n2/8/3Q4/2N3P1/PP2BPP1/2R3K1 b - - 0 1 p02540 b wolf212768 1130 continuation important here ! p02540 b KingKarrl 1163 Invite everyone to the party. p02543 b UriBlass 1852 relatively easy Qxd6 is needed to prevent Qxd2+ and later there is a simple win of a piece only by captures. p02543 b Pinsu 1601 ¿? p02550 b wolf212768 1130 too complicated for this rating. p02554 w KingKarrl 1163 Wow.

I also agree with chessidiot that they should move the pawn on h6 to h7. Then on Nxe4, white has Rb6! p02865 w barz 1708 Position : 1r4k1/5pp1/3R3p/3N4/4p3/2P2P2/1r1n2PP/R5K1 w - - 0 1 p02865 w UriBlass 1852 Nxe4 Ne7+ with Nf5 and white get a knight for the rook and there is no reason to play Nxe4 when Rb1+ is more forced and win a rook for nothing. I think that starting to think about Nxe4 is bad thinking because it is better to think about a check that force the opponent move first. p02867 w smotherhubbard 1838 threat is Rxh5+ and Qxc7 p02875 b UriBlass 1852 problem 23320 to solve 7.2 seconds took me time to see trading with the the fork Bxc5 after it. later moves were easier including Kb1 when I have no fear from checks because I can capture the attacker. p02875 b UriBlass 1852 3.7 seconds remembered after first move. p02875 b UriBlass 1852 1.3 seconds p02883 w wolf212768 1130 its very tricky for this rating. p02883 w TheTornado 1346 It's is proper. p02890 b DocB 1237 I"TO STONED p02890 b mangy1723 1242 wow p02896 b Boriskudelin 1754 :) p02898 w theKnife 1671 Just for optical reasons... p02898 w mburch1974 1481 lol p02898 w Threepwood 1592 why is that the solution???? p02898 w rathkeltair 1694 not Rh2 because castling may still be possible... p02904 b hmpf142000 1670 schööööön p02904 b plopje 1678 very obvious p02904 b UriBlass 1852 8.2 seconds plopje, nothing is obvious with all the checks and it is easy to choose a wrong check if you try to solve it fast. Fortunately I chose the right moves. p02907 w wolf212768 1130 removal of defence :) p02922 w UriBlass 1852 problem 23364 to solve 3.3 seconds thought Qh3 Bf1 so put the queen at h2 p02925 w Holy 1098 Very interesting. You're going to lose the knight, but you need the tempo in order to capture the rook safely. p02925 w Holy 1098 OK, I just looked at the Crafty analysis, showing that my comment is incorrect, and I only go this problem correct by luck! p02925 w Holy 1098 I'm changing my rating of this problem to five stars.

Kf1 white is better off than the more immediate and palpable threat of 1. Nxb4! hahahaha! This is my new least favortie problem on all of CTS. p02954 w JoshBrack 1626 oh no this problem isn't bad i'm the one who's no good. hehe. another false alarm from me. sorry. i read the crafty analysis line wrong. looking at it now, i think the answer is the right one. p02954 w joakimvitriol 1661 r1b2rk1/pp2bpp1/2n2n1p/q2p4/N2P3B/P2B4/1PQ1NPPP/R3K2R w KQ - 0 1 p02956 b edgy 1645 why not Ne1? p02956 b SamuelS 1574 The best move after 1...Qxd4 is 2.

(with check) and Black is fine. p02956 b kwanpin 1752 nice retreat knight move p02956 b mykingislonely 1861 I tried Ne5 to prevent Qf6. Didn't see Nc1. Nice problem. p02958 b wolf212768 1130 hmmm, those pawn moves..... p02959 b underated 1374 good material grab. p02959 b wolf212768 1130 showing 2nd move isnt necessary. p02964 b UriBlass 1852 3.8 seconds p02964 b UriBlass 1852 7.5 seconds this time p02964 b LowestRd 1946 Ratings can be deceiving p02965 b gphilip 1239 Rf3+ seems to be equally good. p02965 b wolf212768 1130 yeah, i also found Rf3 ok, have to look up fritz ;) p02965 b sleiman 1406 Rf3+ is not the same, as it is met by Nf6 p02965 b scuba 1321 i agree about Rf3+, that was what i played first p02966 w flatman 1502 1...Qe2 also mates in 3!

Doesn't ...Qe2 fail to Qxd5+ ? p02966 w MichaelJMoreau 1318 Hey bluepawn, if I'm not mistaken, 1...Qe2, 2.Qxd5+ doesn't avoid the mate. p02966 w Hyperbeam 1761 Qe2 wins... Qxd5+ just postpones it a move. p02966 w LowScore 1564 Okay there is mate in 3 with 1...Qf3 and mate in 4 with 1...Qe2. I agree this is ambiguous and thus not a very good tactical problem to solve. p02966 w schttnsldt 1576 Hi Lowscore p02966 w onat 1932 not a good one Q p02966 w onat 1932 not a good one Qe2 mates too p02966 w road2nowhere 1642 played Qe2 too...suspect that is more natural to most human players rather than comps...so you see that first and stop calculating. They should really remove this one p02966 w DomiDoud 1417 Remboursez!! Dame e2 mat en 3 p02966 w MMan 1255 Agree, Qf3 is mate in three, Qe2 is mate in four, and Rxe5 (2.Qf2,Rxe1+ 3.Qxe1,Qf3 4.Qe6+,Kh8 5.Qxh3,Qd1+ 6.Kg2,Qf1#) is mate in six! p02966 w Vandebent 1701 There are way too many of this frustrating problems with multiple solutions on this server. p02966 w drad 1651 agreed p02966 w mykingislonely 1861 Qe2 is actually a mate in 3, so it's not even any worse than Qf3. This problem should definately be fixed. p02966 w mykingislonely 1861 Maybe by removing the knight on b1? p02966 w camembert2 1625 Not sure why the Crafty analysis doesn't pick it up, but yep, ...Qe2+ also mates. Do these problems never get edited? Looks like it's been this way for years. p02966 w tngerb 1486 Yeah I went with Qe2.. much nicer. p02966 w neiking 1591 Qf3 mates in three and Qe2 mates in four.I don't see the difference as long as it's mate. p02968 b JSorel 1664 126.8 seconds (o_O) p02968 b grom43 1654 Wow, I was quick at 37 seconds I guess. :-) p02968 b television 1655 the problem is not special. 17,5 but i think i was too slow p02970 b Elroch 1453 Unusual trapping of a piece p02970 b Eclectico 1461 awfully hard to see in 3 seconds for a 1600 p02970 b floreatdunum 1719 nice rook trap p02970 b tjumen 1598 very unusual trap, nice p02972 w underated 1374 speed kilss on this one. missed it first time round. dam it! p02972 w JacobTomlinson 1263 whoops... p02974 w theKnife 1671 r1b3rk/4qp1p/p1nppp2/1p6/4P2P/5N2/PPPQ1PP1/1K1R1B1R w - - 0 1 p02992 w notyetagm 1467 White missed the nasty ZWISCHENSCHACH 2 ...

If 2.Kh3, the Queen can fork the King and rook, winning the rook. p03008 b Draxus 1194 The solution to the problem is poor. There is nothing stopping the pawn from taking the rook. p03008 b BabalooMoon 1278 If the pawn takes the rook then 2.Bxb5 p03008 b underated 1374 I agree with the top comment.

Then the resulting LOOSENESS of these two PINNED pieces leaves Black unable to move -any- of his pieces, which I call PINNED + LOOSE = ZUGZWANG. p03021 b grom43 1654 lol. edgy, 2 Nd2 Bxf2+ and Rf4+. notyet: what? p03024 b milos62 1916 A poor problem since d7 wins as well. p03024 b mykingislonely 1861 I agree, p03024 b tomohawk 1833 Agreed.

If I'm reading this right, if White doesn't play the extremely obliging 2.g3??, he's just winning. Stunningly bad problem. p03420 w caliban 1688 I agree with edgy if white plays 2.Kg1 or 2.Ne7+ then 3.Kg1, he can escape from mate. p03420 w SamuelS 1574 1. Nxc8 Qh5! 2. Kg1 (or 2. Ne7+ Kh8 3. Kg1) is not any better for White: 2...Ng5 and any pawn move loses to 3...Qh2# or 3.Be2 Qh2+ 4. Kf1 Qh1#, and finally 3. Bd3 Qh2+ 4. Kf1 Qh1+ 5. Ke2 Qxg2+ 6. Ke1 (or 6. Kf1) Qf2#. Other defences lose as well. p03420 w caliban 1688 I don't think your variation is correct SamuelS,3.Bd3 Qh2+ 4.Kf1 Qh1+ 5.Ke2 Qxg2 is not a check since there is still a pawn on f2 that you can defend with a rook for instance. p03420 w tomohawk 1833 After ...Qh5 Black is threatening ...Nf3#, so no need for a king chase if no g3 p03420 w edgy 1645 Why is this problem still up, when the Crafty analysis shows that 2. Kg1 Ng4 3. Bd3 wins for White? p03420 w kwanpin 1752 Qh6 not good? p03420 w UriBlass 1852 why do you use the analysis of Crafty to decide that white is losing.

Not all good problems can be difficult, and not all easy problems are poor problems just because they're easy. This problem demonstrates several subtle principles regarding endgames, such as the threat of pawn promotion, the square, and knights' inability to stop pawns in many situations. p03887 w pdazz 1388 the pawn can be caught much later, after the solution it still seems lost p03887 w JamesBJames 1657 After the solution, it's pretty much a dead draw. Black brings the knight down to d6 and moves the king down to take the c and f pawns. p03887 w TheKingIsBack 1546 Which side is White and which side is Black!?!?!?!?!? p03887 w rockym 1626 Side is indeed confusing. Although there is a black square at the bottom right. p03887 w MaltaCross 1155 Checking the King wins Black a TEMPO, consequently allowing him to stop White's advanced pawn from queening. p03889 b UriBlass 1852 4.0 seconds p03896 b curiouschild 1223 wins the knight p03904 w suddenlysomeon 1276 Knights are good to prevent promotions. p03907 w UriBlass 1852 20.1 seconds p03916 w underated 1374 keep everything nice and tight. p03916 w underated 1374 back again...sucker for punishiment. p03917 b Svenja 1588 The "solution" is a mistake of the crafty used. If one continues the variation after 3.Nf3 Bxb2 4.Rxd7 Rcd8 one can easily see, that White has absolutely NOTHING in this variation. So 3.Bxf7 might even be worth a try, even though only a computer could come up with such nonsense. p03917 b milos62 1916 What has an extra piece. p03920 b UriBlass 1852 15.1 seconds p03920 b UriBlass 1852 7.1 seconds p03920 b UriBlass 1852 2.0 seconds p03937 b MaltaCross 1155 Nice pin! p03955 w UriBlass 1852 24.4 seconds p03955 w MagicCat 1621 1.7 secs p03955 w tjumen 1598 7.5 seconds p03955 w barz 1708 1k2r3/pp3p1p/q2b1pb1/3PnN2/8/2r3PQ/P4PBP/RRB3K1 w - - 0 1 p03955 w grom43 1654 Enjoyed solving.

Most seem to dislike them, but the more "real" the problem is, the better it is in my opinion. Real games are full of "simple" recaptures. Note that the rating of this problem is currently 1370, indicating that plenty of people miss this one. p03973 w KnightOdds 1102 I think the problem has a higher rating than it deserves simply because people are taking time looking for the "tactic" that isn't there. The problem preys upon expectations in a way that would not be present in a real game - unless your opponent is allowed to hold up a big red sign that says "Tactic here!", only to hold up another sign, after you've wasted time on your clock, that says, "Psych! p03973 w baykemik 1292 Eventually that's the third similar nonsense i encountered today p03973 w ankka 1302 crap p03973 w oaklandmatt 1282 +1 for waaek p03983 b moegigo 1611 with that rating i was only looking for not to take the knight p03983 b Stress 1659 You have to look further. p03984 w Elroch 1453 Nice variation on the ladder and hook p03987 b MaltaCross 1155 discovered attack! p03991 b Hyperbeam 1761 This was a REALLY wussy type problem...! p03991 b rathkeltair 1694 bit random p03991 b JoshBrack 1626 that was a funny ending. there was a noise inside my head that went, "waa, waa, waa!" and then a crowd laughed. it freaked me out. p03995 w floreatdunum 1719 Poor; black's easily winning in any case. p03995 w tomorrow 1550 power of king and quick recognition of a helpless pawn p03995 w sarciness 1465 Bf6 looked winning to me. Clearly solution is the better move, though. p03995 w grom43 1654 Mate in two has to trump whatever else Black has going for him. Nice theme as pointed out by tomorrow.

And besides making the above assessment quickly, the tactician has to spend time asessing the possibility of trapping the white queen. p04038 w joker 1499 To spacecowboy: the problem is made easy by the fact that you only have to guess the first move, otherwise realizing that you have to go for the perpetual wouldn't be easy p04038 w LaskoVortex 1327 To easy to guess correctly. White can win the Knight if he aborts the perpetual check, so it gets confusing--the unprotected rook is now attacked, and so you must look deeper. Then you, after you realize winning further material is hopeless, you have to back-track and see if you can move the rook off the back rank safely to threaten mate in two. When you realize that is impossible, then you have to go for perpetual check. p04039 w underated 1374 taht is an absolute pisser of a move. love it... p04041 b MaltaCross 1155 an amazing mate with the Queen and bishop p04041 b vdLeden 1530 nice combo to remember p04042 b floreatdunum 1719 pretty easy for 1878! p04042 b rathkeltair 1694 easy for 1866! p04042 b tomohawk 1833 Book trap in the Scotch. p04046 b polgary 1530 acc. to crafties evaluation it lost in any case - this is wrong p04046 b musiclife 1602 it's called play the best move.

I understand the striving for a clean win, but I think given the time constraints on this site, that one win should not be preferred above another. There simply isn't enough time for Lasker's advice, "If you see a good move, look for a better one." I think these types of problems are rather unfair. p04245 w mtavakol 1750 Right. p04245 w wald 1565 While I tend to agree with floreatdunum's general argument, I don't think it applies here, for the difference between moves Re6 and Re5 is substantial. The latter is only just winning (mind that in the starting position White is two pieces up). So in any real situation (and I hope you consider this site as a useful exercise for real games), the little time for judging which of the two moves is better is well invested. p04245 w Eviltactician 1509 I have seen another position where two moves were crushing victories, but the Re6 move wins on the spot, whereas the Re5 move might win with best play but in practice white has plenty of material after Qd5 and black has to prove the win over several moves. Definitely Re6 should be the only correct move here. p04245 w yean23 1581 Its a fine line between a dodgy problem and a great problem I must say. p04245 w tacticaldeep 1821 Im IGM and like this problem because there is real difference between the two candidate moves p04245 w nerdesin 1961 i have seen a lot of problems but this may be the best for 1595 p04245 w asktanote 1921 may be the best for 1595 or also for 2000 p04245 w UriBlass 1852 Re6 was losing for me in the practical sense because I used all the minute to find why it is better than Re5 so I lost 1-0 against the problem. p04245 w QuickFire 1582 Took me a while, but I think it was worth it. p04245 w SimonW 1599 I missed the Queen move whilst trying to decided between them p04245 w JoshBrack 1626 i'm usually the first to bitch about dual solutions but come on people! look, white is up 2 pieces at the start so the difference in getting a checkmate or a queen for a rook here is like night and day. p04257 b underated 1374 and the rook goes ohhh! p04260 w Mudfrog 1302 standard backrank mate p04264 b SmokenFlames 1418 Trappy p04265 w hmpf142000 1670 no tactic... p04265 w UriBlass 1852 14.6 seconds the tactics is defending g7 p04265 w UriBlass 1852 2.5 seconds and now the tactics of memorizing problems that I solved. not always works but this time worked p04269 b MagicCat 1621 1.5 seconds p04269 b Alseki 1484 The knights go wild! p04270 b FARKINDAMIYIZ 1941 this is more then 1608. this is more difficult then a lot of 1900 problems because of qc8 bc8 rc8 qd7 rc7 qa4 ne7 p04270 b urko62 1401 Why not just 2.Nxf6+ followed by 3.Qd3? doesn't this preserve the one piece ahead material superiority? p04270 b tomohawk 1833 I don't think so, urko62.

Maybe 3.Nxe6 (threatening mate) 3...Bf6 4.Rxc8 is better, but then 4...Bxc8, pinning the knight with ...Rd6 or ...Re8 to follow, seems annoying. p04549 b spacecowboy 1394 I agree with edgy's comment of 12-02-05. Hey camembert, your comment says you think maybe 3.Nxe6 is better than 3.Rxc8. I am a little more sure than you are that 3.Nxe6 is best. Crafty also judges 3.Nxe6 to be best. Did you look at the analysis by Crafty which was presented to help you assess the position? Crafty's assessment score of 2.Bxe6+ is +1.63, which means a decisive advantage for White. So Crafty agrees with edgy and myself. So this problem is a dual because it has a dual solution. Many tacticians, such as edgy and myself, believe duals are bad problems. I think this problem should be removed. And furthermore, this problem should have been filtered out in the first place because Crafty identified it as a dual. p04549 b flatman 1502 +1.63 is ordinarily considered to be easily winning. True, the accepted line is even better, but it still looks dual to me. p04549 b Pinsu 1601 2.Bxe6+ Nxe6 3.Rxc8 also wins p04553 w OldPatzer 1054 After R(d8)xd3(N), R(d3) threatens Rxb3(P) or Rd1+. p04553 w MaltaCross 1155 How Black moves to block White's dangerous passed pawn (note Crafty's line below) is quite interesting. p04554 w UriBlass 1852 7.2 seconds p04560 b drad 1651 every pawn counts p04561 b Holy 1098 Wins material and removes the pin with tempo, to win the queen. p04568 w Kacparov 2002 very nice p04570 b drad 1651 damn damn damn.. tried to move bishop in the last move p04570 b drad 1651 haha I just read the line for Bg5+.

"Strike whilst iron is hot" p04859 w JoshBrack 1626 failed it. missed the queen sac yet again i can't seem to see a back rank mate anymore. :( p04862 b UriBlass 1852 16.8 seconds took time to see fxe4 threats the knight by Rxf6 p04866 w MaltaCross 1155 What a nice fork! p04869 b UriBlass 1852 played too fast Qxf8+ missing Be7(with one more second I could find that Bd6 is better. p04869 b UriBlass 1852 again same mistake p04869 b Arkenshaw 1733 Black can still play 2...Be7 after , 2. Bd6 anyway... p04870 b UriBlass 1852 2.5 seconds relatively easy win of a rook p04870 b UriBlass 1852 3.2 seconds p04871 w pmevans 1119 Tempting unprotected pawn leads to a nasty Queen trap! p04872 w frigo61 1670 beautifull p04872 w barz 1708 r2qkb1r/2p2ppp/p2p4/1p1Pp3/2PnP1bn/4BN2/PPB2PPP/RN1Q1RK1 w kq - 0 1 p04872 w JoshBrack 1626 lol! i spent the first 3 seconds making sure that all the stuff on the 8th row wouldn't come into play, and then what happens? i didn't realize the queen could get involved in such a case. p04873 w pkendal 1520 Instructive. p04875 b gatorfan948 1426 Sets up a pretty smothered mate if black chooses to last that long. p04875 b mathaias 1434 Fantastic! p04875 b Vapor20 1358 Leads to phildor's mate - Awesome. p04881 b notyetagm 1467 2 Bc1-f4! is a nice example of COORDINATED play. The White e5-queen makes the b8-square LOOSE next to the Black c8-king and 2 Bc1-f4! COORDINATES (REINFORCES) the White pieces against this weakness. Black is forced to meet the threat of Qe5-b8# by BLOCKING the line e5-b8 on the d6-square. But Black insufficently controls d6 and so loses a piece after 3 ... Bc5-d6 4 Qe5xBd6 Qc6xQd6 5 Bf4xQd6. p04881 b sarciness 1465 Nice quiet move. p04883 w KingKarrl 1163 Careful, Kh7 seems better at first, but is a killer. p04890 b BughouseMaster 1555 Nice problem!! TOUGH! p04890 b wald 1565 quite nice, though obvious p04890 b tomohawk 1833 Funny solution. p04890 b floreatdunum 1719 bloody obvious p04890 b Hyperbeam 1761 HEY...! It's not that obvious. We have no way of knowing if you actually got the problem yourself. p04890 b floreatdunum 1719 ok - not bad! p04890 b grom43 1654 Funny solution. Right. 2 Rc8 would be great, too, if not for black having mate. The checks force mate and save white. p04895 w mykingislonely 1861 This would have been difficult, but I was in mass guessing mode. ;) p04897 b joakimvitriol 1661 uncovery p04898 w abcdef 1573 this is certainly above 1400 rating problem p04898 w Holy 1098 Great endgame problem. It's amazing that Black can ensure a draw, no matter what White does, even with the Black king so far away. p04902 b Hexalingual 1342 mate in 1 p04902 b OldPatzer 1054 Mate with B and N: Ne7#. p04902 b mathaias 1434 Great! I was looking at the rook and bishops and misssed the mate. p04902 b mathaias 1434 And the second time around I did the same thing!!! p04904 w Quietus 1704 Line should continue p04904 w LaskoVortex 1327 Very easy to see, not sure why its rated so high. Bonus is that if Kf2, then Ne4+ pops the queen. p04904 w UriBlass 1852 It is not very easy to see It is easy to blunder by Nc4 I do not understand why it eated so low(only 1527.2) p04906 w underated 1374 remove the back rank defense. logical p04912 w Subrosian 1658 What the heck was white trying to do? p04912 w Subrosian 1658 Wait, nevermind. p04912 w ajotatxe 1405 Antichess? p04912 w MaltaCross 1155 the power of the mighty pawn :-) p04920 b joakimvitriol 1661 first counterattack p04923 b mathaias 1434 I only looked at Kxb4 and Rd1+ but completely missed the mate! When will i learn to stop and analyze??? p04923 b brulla 1444 The point is not to analyze, but to SEE what is on the board! p04923 b MaltaCross 1155 A mate with just the rook and king! p04923 b ankka 1302 lol p04927 w UriBlass 1852 15.5 seconds p04933 w jideck 1520 nice, but must have higher rating p04933 w MaltaCross 1155 Queening a pawn is more valuable than capturing a piece! p04938 b czukay 1427 good combination p04938 b UriBlass 1852 3.5 seconds p04939 b UriBlass 1852 4.4 seconds p04939 b barz 1708 r3k1r1/3n1p1p/1q2pp2/1Rb5/3p4/5NB1/P3QPPP/3R2K1 b q - 0 1 p04941 w Gnam 1453 very nice p04941 w joakimvitriol 1661 back rank and maybe there is few weak squares around K not only one p04946 w stefanT 1521 Quite difficult to see p04951 b askon 1240 nice play i immediately went for the d5 with my bishop not realizing.. p04953 b UriBlass 1852 17.4 seconds hesitated too much after seeing it because was not sure it is good defence p04953 b UriBlass 1852 7.1 seconds p04953 b tjumen 1598 defense! p04957 b SmokenFlames 1418 Clasic! p04961 w bwtaylor 1447 always look for forks, even if they are far away! p04961 w PhilGE 1198 bwtaylor is right,and that applies to all tactics. p04966 w Hexalingual 1342 mate in 1 p04966 w mangy1723 1242 so easy I almost missed it p04966 w oaklandmatt 1282 So easy I missed it. p04969 w sehidimizsin 1954 not bad for 1590 p04969 w floreatdunum 1719 Like this one; simple, uncluttered, includes a typical endgame manoeuvre moving a rook along the back rang to be protected by the king. Nice. p04969 w Chessdoom 1586 Think its great, a problem you can run into in a REAL match! p04969 w izicik 1960 nice p04969 w Hyperbeam 1761 Yes, a useful problem indeed. p04969 w UriBlass 1852 3.4 seconds got it in the past so remembered p04970 w UriBlass 1852 problem 23403 to solve 3.2 seconds memorized the solution but not the reasoning. thought about Qe3+ and Qxd4 and missed the simple Bxd4 but decided to play it because of confidence that Nd3 is the move. p04970 w JoshBrack 1626 just using a queen threat to reomve the defender of d4 to win an exchange if i'm not mistaken. p04971 w Carbonic 1527 !!! p04972 b MaltaCross 1155 the might of the pawn! p04973 b underated 1374 nice queen trap.. p04975 b MaltaCross 1155 If 2...Qxc6, then 3.Qe7+ (winning the rook). p04978 w Fred 1456 what's wrong with Rd3+? p04978 w Fred 1456 Actually I found out: I couldn't take the Queen...feeling silly p04978 w Sidorsky 1502 i was fooled the same way p04978 w UriBlass 1852 problem 23454 to solve 21.9 seconds too much thought that there may be a trap of mate after Re1+ when Re2+ is not the best move. p04978 w drad 1651 I was abit quick thought Re1 might have been mate didn't really look I'll admit ;) p04978 w ibis 1460 Rd3+ mistake too. p04978 w Alseki 1484 Good problem. p04985 w UriBlass 1852 problem 13142 6.1 seconds p04985 w bumbly 1561 not sure why, but I liked this problem p04985 w grom43 1654 Because your queen travels a triangle ending with a capture that, at the same time, defends your rook. p04987 w tpollet 1651 Toujours très instructif les finals et souvent très fin p04987 w UriBlass 1852 11.2 seconds too much time to see the second move p04988 b theKnife 1671 over evaluated p04988 b UriBlass 1852 3.0 seconds p04988 b OldPatzer 1054 Q fork: Qa4+ attacks K(e8) and N(g4). p04992 b Rabatt 1256 single forced move, AGAIN! somebody write a filter for these! p04992 b mnd15 1272 I agree with Rabatt p04992 b ankka 1302 I think one could write a Chess Tactics Server client that a) does not allow illegal moves to be made and b) automatically makes the only legal move, if such exists. p05008 w Arthurrocks 1801 slip/.....stupid p05008 w kpuchon 1458 great problem p05008 w Elroch 1453 cute and technical p05008 w UriBlass 1852 problem 23455 to solve 4.7 seconds p05011 b Fromper 1338 Stupidly obvious p05012 b Quietus 1704 Line should continue p05012 b UriBlass 1852 15.6 seconds problem 23102 to solve. easy but for some reason I thought about different moves in the beginning p05012 b UriBlass 1852 4.4 seconds p05013 w UriBlass 1852 problem 23375 to solve 15.2 seconds too much thinking about lines like Ng4 p05013 w greatkid 1694 2.6 secs p05018 b OldPatzer 1054 N fork: N(e2)f4+ forks K(g6) and Q(h3) p05020 w UriBlass 1852 44.9 seconds p05020 w UriBlass 1852 11.1 seconds remembered that got it but was not sure that gxf6 is the solution. p05020 w theKnife 1671 â—„ Position â–º 5kr1/ppB1b1p1/4P2p/2P2P2/3nN1R1/1p1r3P/7K/5R2 w - - 0 1 p05028 w Holy 1098 Some distractions on the board make this tougher than its rating (rating is suppressed by the seeming obviousness of the knight fork, which happens to be the correct first move). p05028 w MaltaCross 1155 Look out for the knight fork! p05033 b joakimvitriol 1661 r3kb1r/2q2pp1/p3p2p/P3P3/QPpN1PPP/4B3/8/2KR1B1b b kq - 0 1 p05033 b joakimvitriol 1661 Nxe6 and Be2 also winning according to engines p05041 b MaltaCross 1155 unusual back rank mate p05042 b zant 1768 my comment is about another problem (p55490). I think h4 is an equivalent solution. p05042 b UriBlass 1852 problem 23255 to solve 14.9 seconds seemed to me the best move but hesitated too much. p05042 b JSorel 1664 21.5 seconds ... I hesitated too p05049 w JimmyPage 1277 why not take the rook initally p05055 w Hexalingual 1342 pawn promotion p05056 b UriBlass 1852 problem 23163 to solve failure tried to solve fast and played Bxd7+ that is second best. p05057 w Hyperbeam 1761 nice p05060 b MaltaCross 1155 needs another move! p05060 b grom43 1654 needs another move because giving up your queen for a N makes sense, huh? Whoever plays 2...Qe3 to escape the check sees 3...Bf6 don't they? p05061 w FireGarden 1557 Problem would be better except that some people will get it 'right' without seeing the fork 3...Nf4+ The test stops too soon p05072 w stevie 1222 nice! p05085 w mtavakol 1750 why not 1 ... Rxe2 and only then 2 ... f3 ? p05085 w snakehead 1475 White parries the mate threat after 2.Qxe2 f3 3.gxf3 p05085 w UriBlass 1852 13.6 seconds p05089 b jacovanniekerk 1359 easy, but pretty... p05089 b Hexalingual 1342 Forced mate in 2 p05089 b tooslow 1114 fantastic p05095 w wald 1565 I think that 3 Re2 (rather than 3 Ke1 as in crafty's analysis) 3... Bxc4 is critical and should be included in the solution. p05095 w UriBlass 1852 2.0 seconds problem 23096 to solve. relatively easy. p05096 w UriBlass 1852 problem 43115 to solve not good problem It is not the first time that I got it and I fell into the trap 2...R8d3+ that is also winning but not as fast as Re1+ p05096 w UriBlass 1852 correction 23115 and not 43115 to solve p05096 w UriBlass 1852 17.3 seconds too much time thought if to play 3...Rf1+ or 3...Rd3+ because was not sure maybe there is some mate that is better than the queen p05096 w LowestRd 1946 The solution gets you the Queen for free, but 2...R8d3+ also wins p05099 b Fromper 1338 This one should be played out one step further. After black blocks the check with Bd7, white has to play Bxd7, so the puzzle should include proving that you see that. p05099 b OldPatzer 1054 Discovered attack with check: B(d3)b5+ exposes N(d5) to Qxd5 p05103 w jokim 2000 Silly as White can just escape the perpetual by 2. Bh4 or 4. Bh4 p05103 w tjumen 1598 Agree with jokim. Black is lost after 2. Bh4, see crafty analysis below. This problem should be removed. p05103 w LowScore 1564 From the original position, this is a mate in 9 for White: 1.Ne7+ Kh7 (1...Kg7 2.Nf5+ Kg8 3.Nh6#) 2.Rxa7 Qd3 3.Qxf8 g4 4.Qg8+ Kh6 5.Qxh8+ Qh7 (5...Kg5 6.Qh4#) 6.Nf5+ Kg5+ (6...Kg6+ 7.Qxh7+ Kg5 8.Rg7#) 7.Qxh7 Rd7 8.Rxd7 a5 9.Rg7#. After 1.Rxd6 Qh7+, it's still a clear win for White after 2.Bh4 or 2.Kg1, as Bh4 can be played on move 4 as well! This is clearly a faulty problem. p05103 w barz 1708 4Qbkn/p2R4/p2r1p2/2pNp1p1/4q3/6B1/P4PPK/8 w - - 0 1 p05104 w UriBlass 1852 b4 seemed to me too defended and I thought only to prevent defending it so chose Rxa2 instead of Bxb4+ Inspite of my failure I think that the problem is more simple than the rating that it got and hope next time I will remember it p05107 w tomohawk 1833 Pretty bad position for Black even after the best defense. p05111 b UriBlass 1852 problem 23100 to solve 2.2 seconds I first thought to capture the rook but saw in time that capturing the queen is better. p05116 b hmpf142000 1670 beautiful and to heavy for me... p05116 b pkendal 1520 sweet! p05116 b plopje 1678 yes. Difficult to find. p05116 b wald 1565 very nice (and hard to see) p05116 b floreatdunum 1719 like it very much p05116 b parmetd 1645 easy but sweet p05116 b pinguino 1600 it's difficult but beatiful. p05116 b grom43 1654 Especially pretty problem! p05124 w MaltaCross 1155 As far as I can make out, this "tactic" consists merely of winning a tempo (2...Bg5+) and thereafter taking a pawn for free (3...Bxd5). p05124 w dktransform 1479 agreed. not much to it. p05131 b JustC 1198 Isn't this the only possible move? p05131 b cwpetryk 1143 Doh! I didn't see I was in check. LOL p05131 b 9isprime 1250 yeah, only possible move p05138 b UriBlass 1852 16.2 seconds p05138 b UriBlass 1852 3.5 seconds p05143 w wald 1565 the trick is to find the only move which does not loose on the spot. p05143 w Wolfgang 1388 You are right, wald, but this is also not to easy. p05143 w schttnsldt 1576 only-move-aments. muahahahah p05143 w DocB 1237 lotsa gravy on my biscuits p05143 w texas 1392 I see. So when your king is in check, move it away... p05143 w grom43 1654 Actually all moves are forced so far as I recall. Oh, except ({10:Mat03} 2. ... Kg8 3. Be5+ Kf8 4. Bd6+ Qxd6 5. Qg7# $18) But I like 4 Bd6+ Qe7 5. Qg7# better. p05147 w UriBlass 1852 20.1 seconds and earned rating took time to see the idea that is double threat(Bxb6 and Bh2+ winning the queen) p05147 w UriBlass 1852 16.4 seconds p05147 w UriBlass 1852 8.9 seconds p05147 w UriBlass 1852 1.2 seconds p05152 b antielectron 1223 & live to fight another day p05162 w JSorel 1664 subtle... p05166 b BughouseMaster 1555 Tricky! p05166 b MagicCat 1621 2.5 secs No not tricky p05166 b themagician 1543 I agree with MagicCat p05166 b Hyperbeam 1761 The assertion that themagician makes is not true. p05166 b drad 1651 and that's the 20th time I've gotten that one wrong p05166 b JohnSmith 1502 Tricky indeed, bughouse. Forget about the other, contrary comments, dumb pretenders. p05167 w turbo 1322 way too obvious. p05168 b EngrStudent 1315 This seems like a bad idea. It seems like Im giving away my knight for a pawn, opening up his access to the center, and not keeping it. p05168 b theKnife 1671 No this is good. The queen took confidently on d4, thinking there is no discovered check, but after Nxb5, the only way to meet the threat on d4 and c7 is to take the knight. Then Bxb5+ wins the queen. p05168 b MaltaCross 1155 Good, but needs extra moves! p05169 b UriBlass 1852 4.5 seconds p05169 b grom43 1654 er, sorry, how's that rated over 1000? p05174 w OldPatzer 1054 Pin: After 1...Qxg6(N), if 2.fxg6(Q), then 2...Bxg4(Q). p05174 w KingKarrl 1163 What a set-up. p05175 b tact 1326 stupid boy fuck , idiot , shit shit shit p05177 b KingKarrl 1163 Oh, wow. p05182 b Krikke 986 2.Rd8 is check. p05182 b centaur09 1228 What p05182 b gabbytay2123 1360 confused p05182 b DocB 1237 ahhhh, yeah ahhhhh yeah ahhy yah yeah p05182 b DocB 1237 ah yeah, ah yeah, ah yah, yeah, ah yeah p05183 b Quietus 1704 Line should continue p05183 b UriBlass 1852 22.9 seconds p05183 b Lioric 1526 line too short p05187 w dwnshi 1559 ZUMMY NOT p05187 w UriBlass 1852 3.4 seconds p05200 w UriBlass 1852 10.6 seconds p05200 w UriBlass 1852 6.4 seconds p05200 w JoshBrack 1626 this problem seems lame. why not 1...nf5 2. bxd8 nxe3 3. bxc7 nxg2 4. nc3 ne3 5. Re1 p05200 w grom43 1654 @JoshBrack. Er, doesn't black have two rooks in your line? p05200 w grom43 1654 And 5...Nc2 seems to preserve Black's rather large advantage in your line? p05207 b pdazz 1388 It's such a pity that the solution of this nice 3-move problem is aborted after one move... p05213 b Hyperbeam 1761 very tough - got it the 3rd time around p05219 w IaGueTe 1486 Only move p05219 w mburch1974 1481 lol dumb problem p05221 b edgy 1645 Should include the refutation of 1.f3, at least in the details section. p05221 b nerdesin 1961 f3 Rxh2 p05221 b lepolaputuki 1826 That's obvious enough... once you see that after 2.f3? Rxh2+! you can't play 3.Kg1 because the bishop at e2 is hanging, which I didn't. p05225 w Auge 1591 High Noon! p05225 w UriBlass 1852 blundered by fxg6 that remembered from similiar problem but different p05225 w JSorel 1664 1.0 seconds p05225 w television 1655 its neccesary to have seen the protection of the rook by the knight. i liked it p05228 b UriBlass 1852 blundered by Bxf5 and did not see that Bxf5 protects e8 by the rook a8. p05232 b UriBlass 1852 42.2 seconds thought first about Qxh6 but it does not work after gxh6 Rxh6 f5 and later saw the threat with Rxh6(Rh8+) p05234 w MaltaCross 1155 mate in 2 p05235 b drad 1651 I'll have to remember this trick p05235 b UriBlass 1852 1.4 seconds I remember this trick. p05235 b MagicCat 1621 I'll have to remember this trick p05241 b edgy 1645 needs more variatuions in explanation p05241 b tomohawk 1833 Okay, I think I understand this problem: if you take with the rook first then on ...Nxe4 Bxe4 covers the N/f3 from ...Qxf3. However, if you take with the B first, then ...Nxe4 Rxe4 will be answered by the funky ...Qxf3, which sort of pins both the R/e4 and the R/g2! Interesting idea. I don't know if I have ever seen such a thing in a game. p05244 w joakimvitriol 1661 actually it is Q trap p05246 b tomohawk 1833 Though, to be fair, Bxe7 is winning as well. p05246 b tomohawk 1833 And almost exactly one year later ... I played 1.Bxe7! ;-) p05249 w olechrhaavald 1193 why loose a tower? p05249 w different 1548 nice checkmate!:) p05258 w floreatdunum 1719 nice mate p05259 w Fromper 1338 This is yet another example of a problem that needs to play out for more moves. Black doesn't actually win the rook if white defends properly, as Crafty points out, but a superficial glance by most players might not notice that. p05259 w dogWaste 1289 agreed totally with Fromper! p05259 w Reini68 1417 +1 p05274 b UriBlass 1852 problem 23406 to solve 3.6 seconds p05274 b theKnife 1671 1r2k2r/1p4p1/p7/3pnQ1q/8/4PRb1/PP1BK1P1/2RN4 b k - 0 1 p05283 b floreatdunum 1719 Nice one.

A recapture. p05285 w floreatdunum 1719 This rubbish still here? p05285 w tomohawk 1833 There should be some problems like this one. The idea is to force people to think like in a game. You don't have the advantage of knowing "some tactic is possible" when playing a chess game. A few false leads will slow down people who don't analyse properly but just pick the most exciting move and trust that because this is a problem site, the answer must be right. p05285 w floreatdunum 1719 toilet training p05285 w Thossk 1840 Excellent work.

Here Black planned the tactical sequence 1 ... Bg7xNc3?? (REMOVE THE GUARD) 2 Bd2xBc3?? (FORK) 2 ... Qb4xBe4+, extracting his b4-queen from the BISHOP FORK by gaining time on the White e1-king, winning a piece. But 1 ... Bg7xNc3?? is -not- check, so White is not forced to play 2 Bd2xBc3??. Instead White rescues his e4-bishop with TEMPO by GAINING TIME on the Black e8-king with 2 Be4-g6+! and only -then- capturing the Black c3-bishop with 3 Bd2xBc3, not 2 Bd2xBc3??. Now Black's attempt to extract himself from the BISHOP FORK by moving his b4-queen with TEMPO does not work because the e4-checking focal point is DEFENDED by the White g6-bishop. So Black planned to save his threatened b4-queen by GAINING TIME with 2 ...

White's Bishop on d5 can capture the pawn on f7, putting the King in check and at the same time opening an attack on the Rook on d8 (by the Rook on d1).

Sure, more advanced people will call it simple, but white must apparently capture with the queen despite it's ability to be captured. A player must look one extra move to see that they can also capture the opp's q if they lose theirs. p05770 w grom43 1654 The only way to keep the piece is 1...Bxd5-c4.

The point seems to be that after white moves the rook, black can win a piece with Bxe2 with discovered attack on the g3 bishop.

The queen can make quick work of Black's pawns and bring out the King for a King & Queen vs King endgame.

Kh8xBh7??) then Black will be mated via a CORRIDOR MATE. The king often cannot be COUNTED as a defender because it cannot go to the exchanging square. So that Black h7-pawn was not attacked once and defended once but rather it was attacked once and not defended at all since the Black h8-king cannot go to h7. p06337 b kpmartin18 1483 nice analysis, Sherlock, want to point out something even more obvious? p06337 b UriBlass 1852 2.6 seconds p06344 w UriBlass 1852 3.9 seconds p06354 b waaek 1120 Nice little fork, but why is this rated 1440, it's more like a typical mid-1200 problem? p06354 b dktransform 1479 too easy. agreed, why is it not a 1200 problem classification? p06358 w colette 1901 quite instructive p06358 w floreatdunum 1719 Fantastic. Got this one wrong, just shows how tricky simple pawn endgames can be under time pressure. More please. p06367 w Holy 1098 Not terribly difficult, but still I just couldn't see it. p06367 w tjumen 1598 i saw it but it took more than a minute... p06368 w MaltaCross 1155 The king is a poor defender of pieces because it has to avoid checks. p06371 w pdubs 1146 Typical pin. p06383 w stevie 1222 trade a rook for knight and a bishop p06389 b OldPatzer 1054 Q fork: After R sacrifice - R(h8)xf8(N), B(e7)xf8(R) - Q(h2)xe5+ forks K(e8) and R(b8). p06389 b grom43 1654 R sac; Rxf8 leads to either 1) mate by Q or 2) Q wins pawn+rook (fork, with check)? p06390 b MaltaCross 1155 Decoying the King with checks to launch a queen fork. The addition of a further move would have been helpful, I think. p06391 w texian 1113 i consistantly fail to see the opening check in positions like these (although this time i caught it) .. attempting any other move than to move out of check results in an immediate error .. since in OTB games "check" is always announced and in on-line play any move not moving out of check is simply not allowed, it seems an attempt to make such an illegal move in these problems should simply be not allowed rather than scored an immediate error .. otherwise, this seems like a fairly easy problem p06391 w theKnife 1671 Saying chack in OTB games is not an obligation. p06391 w loot 1486 check is announced in OTB games only at the beginner level p06391 w joakimvitriol 1661 keeping g2 mating threat p06391 w joakimvitriol 1661 exposed KK p06391 w wild 1305 The touched piece rule would apply, BUT if you were to move as if you weren't in check, it would be declared an illegal move and you'd be able to move again. I think my % correct would be higher if I knew when I was in check. p06394 w OldPatzer 1054 Pin: ...B(c7)a5 pins N(b4). N is lost. p06408 b anamyik 1197 This one should be played out for a few more moves. p06408 b anamyik 1197 This one should be played out for a few more moves. p06408 b Fang 1183 So easy I had to give it that p06408 b MaltaCross 1155 If 2...fxe6, White has a mate in 8. However, this mate is quite complicated to pull off successfully. p06414 w schttnsldt 1576 wtf? p06414 w theKnife 1671 Protects the a8-rook, thus allows to take on c1 next move. p06414 w UriBlass 1852 1.1 seconds p06417 b UriBlass 1852 3.5 seconds p06417 b UriBlass 1852 11.8 seconds checked too much the Rxd3 line p06421 b notyetagm 1467 A nasty trap in the Sveshnikov. p06436 w UriBlass 1852 missed Qh8 and chose Qe2 p06436 w tjumen 1598 missed everything p06436 w drad 1651 hmm got it right te first time and wrong the 2nd.. p06436 w drad 1651 ok ok so it's worth 4 stars p06441 w UriBlass 1852 59.2 seconds p06450 w UriBlass 1852 1.4 seconds remember it p06450 w UriBlass 1852 1.7 seconds p06450 w impromptus 1450 not post your time please? p06450 w drad 1651 that's like asking the sun not to shine! p06450 w rathkeltair 1694 :-) !! p06450 w rathkeltair 1694 :-) !! p06450 w Garryback 1581 drad - fine comment.

A two-move decoy positions White's pieces into a lovely knight fork. The tactic wins a piece for Black. p06477 w inkwire 1667 If $19 means "Black wins", then shouldn't the main line be the one that continues 2.Qf4 and ends in $17? p06478 w UriBlass 1852 29.9 seconds did not see at first itetation that Bc3 threat Kxg7 p06478 w kendal 1531 nice defensive puzzle. p06491 b themagician 1543 underrated p06491 b QuickFire 1582 Took me more than a minute, but it should have been easier. I saw the winning move, but didn't see it gained material until the second time I looked at it. p06492 w Coventry 1613 wow p06492 w UriBlass 1852 8.0 seconds the only way to defend the bishop but looked for something better. p06492 w UriBlass 1852 9.6 seconds p06497 b MaltaCross 1155 double discovered attack p06498 b spacecowboy 1394 Crafty's analysis shows that mate can be forced after Black plays 3...Kf8. But the problem is a dual after 3...Kf8. Either 4.Qd7 or 4.Bxf7 forces mate. Therefore, this problem should be removed. I was robbed today when I failed this problem merely because I chose one dual solution over the other dual solution. p06498 b LaskoVortex 1327 4.Bx7 does not force mate. Black can escape into the corner and his bishop defends fine. p06498 b joakimvitriol 1661 weak K p06504 w underated 1374 love those end games p06507 b tomohawk 1833 Player should have to demonstrate more moves. p06507 b tomohawk 1833 Uh, after 2...f6 that is. ;-) p06507 b UriBlass 1852 14.3 seconds Nf5 f6 Rxg7+ seems good. for example Kh8 Qe7 Ng5 Rh7+ Nxh7 Qg7 mate p06507 b theKnife 1671 r4rk1/1R3ppn/2pN2p1/p1P1Q1PP/8/3qP3/5P2/R5K1 b - - 0 1 p06507 b theKnife 1671 f6 Qe7 (or c7) is the fastest mate, but Rxg7 mates too. p06511 w element 1423 dhlsgwgd... wfsgfewertyuioprdnd.......ruree.../,iyj p06516 b gbekker 1383 It is important to note that without the knight on f6, White threatens to win with Rxe7, since ...Rxe7?? loses to Rb8+. Hence 2.e5 wins the knight. :-) p06516 b pkendal 1520 I'm surprised this problem is rated as low as it is. gbekker points out the winning line, but that's not so obvious. p06516 b Leucky 1538 My first thought was Rxe7 Rxe7 Rb8+, but then Re8 works, BECAUSE the knight guards the rook. So its a "removal of the guard"-problem. p06516 b moegigo 1611 typical low rating problem with more stuff behind if you really look at it p06516 b floreatdunum 1719 as stated needs one more move p06516 b joakimvitriol 1661 attacking back rank defender p06522 w UriBlass 1852 5.4 seconds p06525 b detroitman 1469 d5? p06525 b memo 1570 d5 also wins, crafty analysis notwithstanding. p06527 w UriBlass 1852 6.8 seconds p06527 w UriBlass 1852 6.2 seconds p06527 w UriBlass 1852 3.0 seconds p06527 w UriBlass 1852 1.1 seconds p06533 b KingKarrl 1163 Love these endgame problems. p06536 w Eviltactician 1509 Isn't this a pretty crap problem because white is still winning after he sacs back the piece with 2.Ng5+ or 2.Nf6+ followed by 3.Qe4+ p06536 w edgarcosta 1273 Either case you loose, Ng5+ hxg5, Nf6+ gxf6 Qe4+ Qxe4 p06544 w television 1655 i guess it but i dont understand.

I missed the pin at first too. p07092 w MaltaCross 1155 Basically Black forces an exchange where he comes out a pawn ahead, after an exchange of rooks and bishops.

White wins a tempo in the exchange through a check, thus being able to keep his other rook from being captured as well. p07119 w UriBlass 1852 bad problem because Rxf3 seems to be also winning p07119 w UriBlass 1852 It seems that the analysis of Crafty is simply wrong and Rxf3 is losing. practically I guessed Rxf3 and after seeing that Crafty gives winning score for it decided that the problem is bad. I apologize for insulting this problem. p07119 w UriBlass 1852 8.5 seconds p07119 w Jonathanzzz 1910 I tried Rxf3 too... but I guess it doesn't win.

Black cannot save both bishops and thus loses a piece. p07315 b KABOOOM 1789 IT IS a 1900 plus problem!!!!!!! p07315 b mykingislonely 1861 ??? WAY 2 EASY p07315 b ngnblcn 1851 overrated 1929 p07315 b jokim 2000 Funny p07315 b gloomy86den 1930 The whole idea is that you start looking for checkmate on h5 when you just have to snatch a queen. Pretty dumb though. p07315 b tomohawk 1833 I did exactly as gloomy86den wrote. Took me a minute(!!) to solve. :-D p07337 b benboyleyim 1962 overrated 2222 p07337 b mykingislonely 1861 I disagree (even though it dropped to 2154). With so much going on at the board, it's hard to pick the right move. p07338 b wild 1305 slow-movin train. p07344 w wald 1565 too easy for 1650 p07344 w UriBlass 1852 5.0 seconds did not see Rb1+ immediately so I do not agree I was asked to rate the beauty so decided also to give one star. p07344 w Kacparov 2002 2nd move was not needed p07350 w tomohawk 1833 Tactic from the Marshall Gambit in the Semi-Slav (1.d4 d5 2.c4 e6 3.Nc3 c6 4.e4. p07350 w UriBlass 1852 got it wrong played too fast and missed Qe7 mate in the second move saw that Nxe5 does not work because of Qd8 mate p07350 w UriBlass 1852 6.2 seconds p07354 b stormwarning 1368 nice problem, but should have it run out another move or 2 p07354 b maty 1611 MATĚJPŮLPÁN p07354 b cuong 921 I don't understand why the rook captures the bishop :( p07354 b Alseki 1484 I'm pretty sure that most people don't even calculate with problems like this... p07362 w MaltaCross 1155 exploitation of constricted King p07377 w rathkeltair 1694 what choice is there? p07380 b UriBlass 1852 3.2 seconds p07392 w e4e5f4 1402 Finally a mate in four p07392 w Gooner 1207 Obviously Ra1 is a bad move, since it leads to a forced mate. p07392 w platonisopera 1250 I agree with Gooner on this one p07392 w MaltaCross 1155 [1] In the first move, look out for a fork that on one hand threatens checkmate, and on the other threatens to win a piece. [2] In this particular problem simulation, White replies to Black's first move by moving his forked piece out of harm's way, apparently not perceiving the checkmate threat. This blunder permits Black to achieve the checkmate. p07394 b wild 1305 a couple ways to force mate here I think. p07394 b Holy 1098 Nice. The R is only attacked by a pinned pawn. White delivers mate when his queen is under attach. p07394 b Holy 1098 attack p07397 b Abhishek 1469 http://chess.emrald.net/chess.php?ReviewPos=1176&Mode=review p07397 b Abhishek 1469 http://chess.emrald.net/chess.php?ReviewPos=1176&Mode=review p07401 w UriBlass 1852 2.6 seconds p07401 w UriBlass 1852 4.7 seconds p07403 w Holy 1098 Great remove-the-guard problem, with multiple themes (pin, fork). p07403 w MaltaCross 1155 The fork wins material, and protects the mating square. p07407 w waaek 1120 many distractions, good problem to show the value of looking at *all* forcing moves p07407 w wild 1305 yikes, fooled me on this one... p07408 w OldPatzer 1054 Checkmate: ...R(h8)h1# after Q sacrifice to avoid check. p07410 b knobgoblin 1444 nice to have a little length on a lower-rating problem.

I thought pushing the d-pawn could work (if white took the bait) to win the Q with a knight fork. But I missd the mate combo altogether p07427 w wcahleter 1332 Lo dificil es saber, que la respuesta era jaque perpetuo. The real problem is: won or draw p07427 w mathaias 1434 Agree with loot. I found the first moves easily but did not see that it ended in a draw. p07428 w OldPatzer 1054 Avoiding mate with K(d8)c7 p07433 b ngnblcn 1851 nice p07436 w hardcorepawn 1418 lame. p07436 w wild 1305 not realistic p07437 w UriBlass 1852 21.1 seconds p07437 w joakimvitriol 1661 pin, attacking defender p07441 b Arthurrocks 1801 And why not 3.Bd4?? p07441 b mykingislonely 1861 Bd4 Qh2+ (Kf2 Ne4+) Kf1 Rxf3+ gxf3 and then QxQ p07441 b UriBlass 1852 did not see the threat Qh2+ and blundered by f4 p07442 b UriBlass 1852 19.9 seconds partly mouse problem when I thought that I failed p07442 b UriBlass 1852 3.5 seconds this time p07442 b AlexeiD 1600 Qg4+ also wins... p07442 b JoshBrack 1626 agree with alexeiD. I just don't know why you'd give this crap any more than 1 star. It's poor at best in my mind. ridiculous dual solution problem. I don't think past a clear win and that's why i think in this problem it should be removed or changed so that only 1 solution produces a clear win. After Qg4 white easily gets +3.11 with almost no calculation required. black's not getting out of the loss. p07442 b MagicCat 1621 Yes 3.Qg4 wins too but 3.Qf5 is much faster (3.Qf5+ Kb8 4.Nd7+ and it is a fork and if 4...Rxd7 5.Qxf8 wins the queen) If 3.Qg4 Kb8 4.Nd7 Rxd7 5.Qxd7 only wins a quality. p07446 b underated 1374 logical. p07454 w tjal 1104 after Nxe5, why Bh4+ and not d8=Q ? p07454 w Alseki 1484 tjal; d8 loses to Nc6+ I suppose Bh4+ is given as a move as basically all moves are losing now anyway. p07454 w Alseki 1484 ..also, if Kxh4 then d8=Q+ is no longer losing. p07454 w 9isprime 1250 wow, Bh4+ is a subtle recovery p07477 w UriBlass 1852 3.0 seconds p07481 w OldPatzer 1054 Checkmate with B(f3) and R(g7).

Kg6xf5) the Black g6-king onto the exposed LIGHT-SQUARE f5 so that the LIGHT-SQUARED White c4-bishop can move with a FORCING MOVE (3 Bc4xNe6+, CHECK), vacating the c-file for the DISCOVERED ATTACK of the White c6-rook onto the UNDEFENDED Black c2-rook. p07486 b notyetagm 1467 1 ...

I think i know if Nxh2 is interesting and if it picks up the bishop and pins the rook. I don't think that Nxh2 is interesting. And I don't think it's picking up the bishop and pinning the rook... wouldn't it be Nxh2 Be5+ and black goes down a piece? p07920 b spacecowboy 1394 If a person isn't paying attention, they might miss the fact that en passant is a legal move for Black on move one. I don't know why I don't pay attention better. p07920 b backdingbrob 1457 I missed that en passant was legal... and after 6 minutes of thinking I realized that en passant had to be the move since everything else was horrible... p07920 b tjumen 1598 The problem is easy. I missed the en passant capture. I agree with the above comments, that it mostly requires paying attention. p07920 b MagicCat 1621 this problem is overrated but I happen to be the only 1 who found it ! p07920 b drad 1651 haha yeah I was sipping tea when black made his move and missed it ;) p07920 b gargletheape1 1330 I don't think it's about en passant per se. You see the bishop protecting the king pawn, and even before you see the white move you want to harass it.

So, my question is why does 2.Qxe8+ not work just as well as 2.Rxe8+? p07975 b loot 1486 If 2. Rxe8 Kh7 then 3.

N4PLL p07979 w wald 1565 well, I think the point is that after 2. gxh3 Qg3+ 3 Kf1 Qh3+ and Rxf5 Black has mating threads (4. ... Qxf5 may also work). p07979 w gbekker 1383 After 2.gxh3 Qg3+ 3.Kh1 or 3.Kf1 are met by Qxh3+ or Qd3+ respectively, winning the rook on f5. Perhaps an additional move should be added to the puzzle to make this clear. :-) p07979 w lancer2000 1410 unclear p07983 b HARjustin 1496 whoops, didnt see the queen there =) p07984 w armeno 1859 How can you see this move in so little time?? p07984 w armeno 1859 The move e5 p07984 w grom43 1654 The move e5 is good, the move 3 Be5 is an error.

Seems too easy. p07996 w floreatdunum 1719 niceish p07997 w Holy 1098 Nice combo. This was a tough problem--there are a lot of moves to check and there also seem to be other tactical possibilities to distract the player such as forks and pins. p07997 w grom43 1654 Love this mating pattern. Learned it using the huge Polgar book of diagrams in the mate section. p08015 b UriBlass 1852 9.2 seconds nice queen win p08017 w Jonathanzzz 1910 It's hard to see that you would like a draw.

The candidate shjould demonstrate that he realized that his Queen will be taken and have Rxf2+ ready... p08025 w nm32 1653 This is not really a 1473 problem. 1400s have difficulty seeing the tactics behind fxe4. p08025 w decembersnake 1528 i definitely agree with fred it needs at least two more moves Rxf2 Kg1 Rf6+ winning the queen so they should have more moves in the tactic. p08028 b 9isprime 1250 awesome sequence p08030 w UriBlass 1852 16.8 seconds p08030 w grom43 1654 Find all the right moves! p08031 b UriBlass 1852 3.7 seconds p08037 b Holy 1098 I just lost a game (today) in on-line correspondence chess for failing to see a move almost exactly like this.

The first reason is that the move prior to 1.dxc6 e.p.?? had to be 0...c5?? instead of 0...Qxa5. And yes, I did deliberately number those moves with a zero. The second reason this problem amazes me is that this problem is rated almost as high as 1400; but the solution, 1...Qxa5, is so elementary. I.E. Elementary relative to a 1400 rating. This goes to show that tacticians rated below 1400 tend to overlook tactics along horizontal lines (ranks). p08047 w underated 1374 I tatically did not look along the rank and was going purely up and down. That was an interesting point. p08047 w LowScore 1564 @ spacecowboy: The first reason for your amazement amazes me, because 0...Qxa5 is not possible. The White pawn sits on d5, the 0...c5 is played, and only after 1.dxc6 e.p. Black gets a shot at Qxa5. The fact that people tend to overlook horizontal or diagonally backward queen moves can be seen by the fact that those kind of problems have a pretty high rating on CTS. p08047 w loot 1486 This is awful. p08051 b floreatdunum 1719 Nice, although rather a typical endgame tactic to gain time to capture the rook preventing the king stopping the dangerous passed pawn. p08051 b UriBlass 1852 2.0 seconds p08057 b tomohawk 1833 Isn't this from Ivanchuk v Kramnik? p08058 b exlr8me 1342 Not to bad p08058 b giovmendoza 1350 Beautiful p08058 b sleiman 1406 nice p08063 b OldPatzer 1054 Skewer: White's Rs chase Black's K to h5, where Rxh7 wins Black's Q. p08064 b OldPatzer 1054 Checkmate: 2.

After the more natural 2.Nxg3, White still has winning chances, so the whole problem is rather poor (Black has no winning move and the winning move of Black only comes about because of a White blunder). p08140 w Improchess 2054 2.Nxg3?¿?¿? p08140 w different 1548 not a forcing line p08140 w UriBlass 1852 6.6 seconds p08140 w UriBlass 1852 I disagree with LowScore The target of black is to find the best move and not to win. p08140 w barz 1708 8/p4R2/1kp3p1/1p6/4N1rp/4K1P1/PP6/8 w - - 0 1 p08144 b ngnblcn 1851 nice p08144 b plopje 1678 nice but obvious p08144 b UriBlass 1852 not obvious and took me almost the full minute p08144 b rathkeltair 1694 agree Dutch plop p08145 b Coventry 1613 lol p08149 b UriBlass 1852 10.5 seconds p08158 w UriBlass 1852 missed the simple pin p08159 b smotherhubbard 1838 ok, threat was Qg3+ p08159 b JSorel 1664 standard defensive move p08162 w ngnblcn 1851 not excellent but p08162 w drad 1651 even I could get it in a few seconds ;) p08167 w tomohawk 1833 Looks like a position from the French Tarrasch. p08167 w theKnife 1671 Looks like a problem. p08167 w plopje 1678 very obvious p08167 w UriBlass 1852 bad order of moves too fast thought that 1...Rf2+ Rxf2 Ne1 is mate and missed Kf1 solution is obvious only after you see it so not obvious because did not think about Ne1+ p08167 w UriBlass 1852 failed again this time simply played Bxh3+ missing Nxh3 p08167 w barz 1708 r1b3k1/pp3rpp/1b1B4/3pp3/8/3n1NPB/PP4KP/5RNR w - - 0 1 p08171 b OldPatzer 1054 Double (discovered) attack: e4 threatens exf5(B) and B(f2)xa7(Q). p08173 b MaltaCross 1155 Tut!

QxRa1+ wins an exchange and a pawn. p08883 w macLeay 1639 notyetagm, Qxc2 loses more than the exchange and a pawn. p08883 w knobgoblin 1444 Nice to see a short tactic that requires thought. p08892 w UriBlass 1852 3.3 seconds new rating record 1787.56 p08894 w MaltaCross 1155 the might of the pawn ..... p08899 b chessyeti 1756 3.0 seconds ; p08900 b merendera 1428 rather difficult if you try to calculate the complete sequence from the beginning p08900 b wizzo 1144 having trouble moving pieces p08900 b Holy 1098 Indeed, this problem would be about 1600-1700 if you had to know what you were doing from the beginning, instead of guessing. Great endgame study--it requires a knowledge of queen-versus-pawn-on-the-seventh-rank scenario, and the ability to apply those concepts to this particular situation. p08907 b Alseki 1484 I stared blankly at that one far too long. p08917 w MaltaCross 1155 Hook and ladder trick! p08918 b smotherhubbard 1838 failed, missed 2.Rxd4+ Qxd4 3.Rd3 Rc1+ 4.Ke2 Rxf2 mate! p08924 w trumvirvel 1285 skewer p08928 b UriBlass 1852 problem 23343 to solve 4.2 seconds double threat knight and Bxe6+ winning the queen. p08928 b UriBlass 1852 10.5 seconds p08928 b grom43 1654 The Qa4 appears to be trapped, no? No need for Bxe6+ when white has Rxa4. Qe4 does accomplish win of more material as black cannot even get a rook (..Qxa1 3.Qxf4+ and 4.Rxa1). p08930 b aggron 1280 It is way to hard p08930 b wild 1305 tough problem! p08930 b ankka 1302 where are THE MOVES? p08937 b PeteLP 1174 The given solution seems to be an error. Black can respond QD3, attacking whites queen with tempo and thus saving his knight. p08937 b DeindeCentum 1118 The most beautiful solution is not Qd3. p08938 b MaltaCross 1155 This tactic wins a Knight. The very act of the capturing the black knight at d4 (by the Queen), can also simultaneously serve to defend the white knight at c5! p08942 b Elroch 1453 I don't like problems where the solution is the move that a near beginner would think of as the most obvious. Clearly they only acquire a rating that is not minimal because some people look for something clever that isn't there. p08942 b inno 1429 Elroch, I missed this one for the same reason as you, but I think it takes skill to look at all outcomes, when looking for that "something clever" and it takes skill to realise it isn't there... I don't think it matters that beginners can solve it without too much thought, the point is for us to put thought into it... But that's just what I think... p08942 b musiclife 1602 while NOT a classic chess problem, I'm ok w/ this here while testing. seriously, what other moves would you consider here? Hence, play moves fast once you determine it's best. p08949 w UriBlass 1852 37.8 seconds p08954 b rockym 1626 I went for 3. gxf3, but this allows some counterplay p08954 b judochop 1369 3.gxf3 also allows you to keep that critical f6 pawn. p08956 w sleiman 1406 nice mate p08958 w Hexalingual 1342 mate in 1 p08962 w Arthurrocks 1801 No rxh5?

Thanks for pointing out the Queen interposition, JoeLag. p09005 w MaltaCross 1155 The double check wins the day. The problem with Ne4+ is that White can reply with 2.Bf2! or 2.Qe3! p09005 w slughead42 1138 Nice. I missed the crucial double check the first time through...of course, I'm not very good. p09013 b askon 1240 dumb p09013 b Holy 1098 Excellent. Trapping a piece is not intuitive--you must see all the potential escape squares--AFTER you determine that a trap is even possible. p09014 b rathkeltair 1694 wat da fuck which way up is the fucking board? p09017 w MaltaCross 1155 Black's pawn structure can manage the threat of Rc8+ posed by White's double rooks on the c-file, since black does not have any back rank issues. p09019 w johncox 1840 Too hard for me. Why doesn't 1...Rd2+ win a rook, for example? p09019 w snakehead 1475 Do you see what White is threatening? p09019 w floreatdunum 1719 john??? g5 is a mate threat... p09027 b curiouschild 1223 mate in 1 p09031 b UriBlass 1852 90.5 seconds p09031 b HateYou 1627 2.5 seconds p09044 b grom43 1654 It's a nice problem that forces you to see what's weak in your opponent's position. p09046 b UriBlass 1852 5.3 seconds p09047 b Holy 1098 The alternate move explored by Crafty is a8=B+, which this interface does not allow the player to choose!

So it seems you can only play 2. ... Kd8!, as given in your analysis, or maybe also 2. ... Ke8, intending 3. Qc8+ Nd8. If this latter line is impossible you should include 2. gxf6+ Kd8 in the solution, since, as I said, this seems to be the crucial point in the position. p09388 w UriBlass 1852 31.5 seconds p09388 w tomohawk 1833 Agreed with mtavakol p09400 b Holy 1098 You have to figure out that this is a defensive problem. p09400 b LaskoVortex 1327 But if you figure that out pretty quick, it turns into a pretty ugly problem. p09404 b MaltaCross 1155 a simple fork p09406 w Schumi 1523 Nice.

The problem has now rating of only 1581.2 with RD of 8.4 and I hope it is going to go down. unlike normal recapture when it is not obvious that the move is best here I see no reason to use long time because the recapture is even a mate. I may miss it in the future if I say that it is too easy but at this point of time I even do not understand how and I really wonder what are the errors of the people who go wrong. maybe they try Nf7+ first or maybe they try Qg6 to play Qh7 mate. p09521 b barz 1708 0 star... p09521 b MagicCat 1621 UriBlass, it went up! it is now 1583.6 !! p09521 b grom43 1654 People miss this because they are looking for "tricks" I guess.

Bg5 h6 3. Bh4 g5 4. Bg3 f4 5. e3. The reason, loneknight30 that Qd3 is not good is that there are then several good defences to Qg6#, leaving the bishop trapped on g3. 5. e3, in contrast, allows White exf4 after the mate threat has been dealt with.

The problem should continue until Black's second move, a check from the c-file.

The White pawn on d4 is pinned. If the pawn moves off the d file (if it captures) then the Black queen on d6 takes the White queen on d1 for free. The Black rook on c8 is able to take advantage of this situation by capturing the White knight on c5. The pawn must not take the rook, so Black gets the White knight with no compensation for White. The knight that appears to be protected on that square at first glance is actually not protected. p09805 w Hyperbeam 1761 Fiendish. p09815 w thingfish 1345 nice decoy. p09817 w floreatdunum 1719 what on earth is that all about? p09817 w kendal 1531 What that is all about, you fucking idiot, is that you have to see that you have to protect the rook. p09819 w UriBlass 1852 2.3 seconds p09819 w UriBlass 1852 1.8 seconds p09824 b UriBlass 1852 1.9 seconds need to threat potential indirect attackers p09827 b JacobTomlinson 1263 Too easy p09830 b UriBlass 1852 problem 23379 to solve 2.1 seconds relatively easy for the rating. p09831 b pkendal 1520 What is the differnece between 3.

Rh6 thinking white would mate. After 3. RxB black will take back the exchange with either Nf1+ or Ng3+ and RxR. It seems like Black has some chances to draw after Ng3+. p10050 b rootzero 1332 Agreed, I was thinking about a mate, not material. p10050 b AngryPirate 1308 i did he same thing 8-( p10050 b ristovak 1211 Thanks bwtaylor p10050 b Elroch 1453 This is actually a difficult problem hiding behind a low rating. Some people undoubtedly spot the rook fork to win the bishop without thinking of trying for mate with Rh6. Rh6 would be the right second move if black did not have a less than trivial mate in 3 in response. p10050 b JoeLag 1409 I played Rh6 ... and I have to rate the problem as poor. Beauty would only be there for BLACK if white plays Rh6. Thanks to bwtaylor for his explanation! p10050 b UweD 1405 I played Rh6, because thinking through the whle defense/black to be mated complex would have overdrawn on time anyway. I gues statistically the way emrad is designed it will give more points in the long run to go for mate and get 90% of the points and get shafted 10%... in the real world of course that looks better. HOWEVER what makes me upset is that I was told to assume a blunder by black in every move...; which black does in move 1: the pawn move, why does black not plat Nf1+ straight up??why should I suddnely assume that black does not blunder on its second move?? Weird and upsetting inconsistant, irratic opposition behaviour, almost like politics... p10050 b Holy 1098 Excellent and difficult problem. UweD's complaints are not legitimate. This problem is correct at all stages. The solution move at each point is definitely the best move for that position. The opponent's preceding move should not impact your approach to any move in any manner whatsoever. A legitimate complaint would be that poor play by the opposition must happen in order for any move to be the "correct" move. If that were the case, then the analysis would show thta there was a better move for the player to make, becasue the analysis assumes that the opponent will make the best move available. That is not the case here, or in any problems on CTS. The second move by Black in this problem was correct, because Black avoided Rd8#. The player must see that he cannot get mate (just threaten it with the first move) but can win 2 pieces for a rook. The player also must see that he cannot win the bishop outright with Re6+, but it's still the correct move because even after ...Nf1+ or ...Ng4+ White will win the knight and lose his rook. (Unfortunately, a lucky, quick-moving player can simply make the forking move, not realizing that he can't win the bishop, but only B+N for the R.) p10050 b joakimvitriol 1661 not easy to see that there is no mate for black after R takes B p10050 b Platinumtdj 1470 I have seen 2000+ rated problems less difficult than this. I suppose that the rating of a problem is evaluated from the rating of the people who solve it... but in this case most of the 1300-rated tacticians have simply looked at the fork without seeing the possible mate of white with Rh6 and the mate in three of black (and also the check with Ng4+). I mean, for resolving this problem it's better to be a little dumber... lol. I think this problem could be in the nightmares list of many high-rated tacticians. Anyway, it's too bad ruining a problem in this way... there should be some defence to the bishop and we could have a nice 2000+ problem. p10050 b phmilet 1553 The problem is great, but is severely underrated. As most people have pointed out, low-rated tacticians that spot winning the bishop probably dragged this problem's rating down. Deep problem though. p10051 w tpollet 1651 Difficile et réussi.

After 12 Kb1 Bd3+ and a6 with no real weaknesses for black compared to three weak pawns for White and a king trapped on his 1st rank? You get a losing position at the end.

This way, white loses the Tower.. p11051 b forkinhell 1388 tibtop, he loses a rook but gains the queen. p11051 b amyii 1354 According to crafty nice line, Black loses a knight vs a pawn p11052 w martynspeck 1289 So simple but so easy to overlook. p11052 w joakimvitriol 1661 limited B p11052 w element 1423 yeah yeah. whatever. p11060 w JoshOvi 1570 Problem is facing the wrong way. Therefore it's not clear in which direction the pawns move. p11060 w Stress 1659 There is a black blinking dot. p11060 w grom43 1654 First thing I do every problem is glance to lower right to see whether I'm white or black. Here "I'm black," I say to self, "and that's a b7 pawn about to queen". Rest is easy. p11067 b floreatdunum 1719 Nice exploitation of the multiple pins p11067 b UriBlass 1852 21.3 seconds nice pins p11069 w ambarishjoshi 1149 why could'nt the pawn not capture the checking rook and prevent checkmate.. with all due respect, i dont think it is a checkmate as u say.. p11069 w ambarishjoshi 1149 the solution as provided by you of Rh3# is incorrect.. in the present problem, the answer to Rh3+ is g4Xh3 p11069 w Holy 1098 Nice combo. The problem is correct as presented. The human player, in these problems, is always moving "up" the board. White, in this problem, is moving "down" the board. Thus, the White g-pawn must move down, not up, to capture. p11073 w UriBlass 1852 14.8 seconds p11074 b rathkeltair 1694 straightforward for 1742 p11074 b barz 1708 2r3k1/1pqnbppb/4p2p/r2pP2P/3p1BP1/PR1P1N2/2P1QPB1/4R1K1 b - - 0 1 p11078 w MaltaCross 1155 A mate in 4 based entirely on Black's strong d-file (i.e. a Queen guarded by a Rook). p11078 w Kenicht 1300 But don't forget it is based upon her ability to seize the initiative against a loose Rook, making it a combination rather than mere positional force. You could say then that if it were based on White's colossal d-file force, it was also based in complementary fashion on Blacks dislocated, peripheralized, loose pieces. Combine a focused force against and unfocused one, and you will get a tactical result in favor of the former. p11081 b kwanpin 1752 Nxd5 Qxc6 pin the king p11081 b UriBlass 1852 played Nxd5 too fast and did not notice the pins(Nxe7+ is good also because of pins when the knight is pinned to the queen and there is also Nxd5 Qxd5+ line when Nxe7 is illegal p11089 b MaltaCross 1155 capture of the pinning piece p11102 w Holy 1098 Great combo. p11102 w curiouschild 1223 I'll take your queen but you won't take mine p11109 b UriBlass 1852 20.6 seconds p11111 b biike 1777 1+1+1+1+1=5 p11111 b UriBlass 1852 19.0 seconds was not sure and was afraid of the passed pawn of black p11111 b rathkeltair 1694 needs at least to show gxf3 Rf5+ p11114 w slacker00 1521 Make black find 4.Kf5 after 3. .. Kb7. It's as critical as any other move in this sequence. p11114 w LowScore 1564 4...Kf5 is not necessary. 4.Kb7 h5 is good enough for black to win. p11114 w Sidorsky 1502 I'm stymied here; In analyzing 2...Nd7+, Crafty indicates that 4...Kf5 is best and that Black is winning, -3.23. But then, in the later analysis of Black's third move, 3...Nb6, which was in the earlier line, Crafty changed it's analysis to 4...h5, and declared the position to be drawn. I'm too lazy to run the position on Fritz, but I think the latter is the more likely outcome. p11114 w Sidorsky 1502 I lied, not too lazy. Fritz says both 4th moves by Black result in drawn positions p11114 w OldPatzer 1054 P promotion: to prevent White's P on c file from promoting, Black's N must reach b6 via a check. p11117 w floreatdunum 1719 Rather poor as Black is losing in any case, although admittedly 1...Kc6 doesn't lose immediately, unlike the alternatives. p11117 w themagician 1543 5.7 seconds yes p11117 w tomohawk 1833 Agreed. Useless problem. p11127 w notyetagm 1467 1 Nd4-c6?? Rf6xNc6! is an excellent example of the tactical theme MAINTAINING A PIN IS A FULL-TIME JOB. The White c5-queen must PIN the Black e7-rook to the Black f8-king to meet the threat of ... Re7-e1+ so the White queen cannot also DEFEND the White c6-knight. MAINTAINING A PIN IS A FULL-TIME JOB: YOU CANNOT MAINTAIN A PIN (f8-a3 diagonal) AND DEFEND A SQUARE (c6-square). p11127 w notyetagm 1467 1 Nd4-c6?? Rf6xNc6! 2 Qc5xRc6?? Re7-e1# p11127 w JacobTomlinson 1263 Yay! Checkmate! I win! p11129 b rocky 1113 very easy p11131 w JamesBJames 1657 A bit easy for 1658. Obvious queen entrapment. p11131 w stefanT 1521 OBvious queen entrapment indeed but still, a fuzzy position with mixed pieces allover makes it less obvious to find though you are alerted of the queen in trouble p11131 w UriBlass 1852 20.6 seconds a bit hard for 1645.8 obvious only after you see Re4 p11131 w UriBlass 1852 9.1 seconds p11131 w sarciness 1465 Messy. p11134 w UriBlass 1852 5.4 seconds p11134 w joakimvitriol 1661 skewer p11135 b UriBlass 1852 12.7 seconds took time to see everything is defended and I can play 3.bxa4 after 2...Qe3 p11136 w Elroch 1453 entrapment p11136 w grom43 1654 block exit route, then entrap. nice problem. p11136 w JoshBrack 1626 so can some one explain to me how this is entrapment? this is nothing like that time i got arrested! (that's a joke, don't get all bent out of shape chess moms) p11141 b wald 1565 crap this! REMOVE! p11141 b underated 1374 would like to see the rest of this as it is as the general consensis says "shit" p11141 b underated 1374 I meant to star it as a one. not three p11141 b Wolfgang 1388 very poor! p11141 b floreatdunum 1719 apart from stroking the ego of fuckwits (look I can recapture uuuh drool), what is the point of this? p11141 b sarciness 1465 Eh? Still, yay for red herrings! p11141 b wild 1305 I like it. There's plenty going on here... potential pawn fork, open diagonals, hanging pieces etc. All tactics possibilities are contingent on the Qxd3 move. p11149 b LaskoVortex 1327 Not really a tactical problem. More like an end-game analysis. Anything but 3. Rb1 looses or draws, but you have to decide first that 3. Rxc5 can at best lead to draw and that 3. Rb1 is safe against Kd2. p11149 b drad 1651 Indeed. 3.Rxc5 Kd3 4.Rd5+ Ke3 and white is screwed :) p11172 b Holy 1098 A lot harder than the rating--lots of themes involved--potential overloading, discovered attacks, forks, mate threats, mate combo, others. Easy if you give the most obvious check first. p11177 b Zuggy 1902 Didn't see Kg7... p11177 b smotherhubbard 1838 2.Re8 Kg7 3.Rc8--instead 2.Re8 Rxd7! p11179 w Elroch 1453 Unprotecting sacrifice leaves two pairs of mutually attacking rooks. p11181 w underated 1374 busy board. but there was something there. p11181 w sleiman 1406 ditto... but should easy to spot p11183 b grom43 1654 Nice problem.

I spent a lot of time on this one. p11351 w joakimvitriol 1661 P-fork + pin p11353 w levkipos 1386 just avoid mate p11353 w SmokenFlames 1418 Not just avoid mate, but it seems that white ends in zugzwang since he can't avoid mate in g2. p11354 w JoshBrack 1626 78.4. wow! so much going on there. p11357 b UriBlass 1852 22.6 seconds was not sure if the advantage after Qe8+ is enough p11365 b Leucky 1538 nice! p11369 w onat 1932 nice p11369 w UriBlass 1852 blundered by Ng5 with fork missing winning the queen by 3...Rf8 problem is bad because 3...Ng5 also wins p11369 w UriBlass 1852 again blundered this time by 2...Kd5(missing the fact that Qxe4 is a legal move to consider) p11369 w UriBlass 1852 1.1 seconds this time trusted my memory when played QxN I was not sure at that time why the move is correct but after 3.Rxe4 remembered that the simple fork that I did in the past was a mistake and saw Rf8 and remembered that this move wins the queen. p11374 b UriBlass 1852 21.7 seconds The time is because I remembered some trap and looked for it but it was from a different problem. p11374 b memo 1570 Ligterink(2470)-Van Baarle(2380), NED 1973 p11374 b floreatdunum 1719 Good spot, memo! p11374 b rathkeltair 1694 four pawns alekhines? p11374 b JoshBrack 1626 failed. i remember failing this one a few times before too. :( i like this one cause even though it's so simple it helps me think a different way than i normally would. p11378 b UriBlass 1852 11.2 seconds p11378 b UriBlass 1852 6.1 seconds p11380 w UriBlass 1852 7.1 seconds p11381 b UriBlass 1852 failure missed the simple fact that the knight is not pinned and Nxb8 is good and played Rxb7 p11381 b floreatdunum 1719 no prejudices - the pin ain't anything p11398 w UriBlass 1852 1.3 seconds p11398 w grom43 1654 This is a great theme. White can lose rook, or queen, or even king. p11403 b MaltaCross 1155 After 2.Kf6, Black must move his King to avoid mate in 1. However, this means that Black's rook remains unguarded, and liable to a skewer! p11406 b tomohawk 1833 Problem should be extended to at least 4.Nxg5 p11408 b UriBlass 1852 14.0 seconds p11408 b MagicCat 1621 2.9 secs p11409 w UriBlass 1852 4.8 seconds got it in the past p11410 w Hyperbeam 1761 Got it the 2nd time around.

Very annoying to get bowled another turf cutter. p11468 b UriBlass 1852 24.1 seconds decided to rank problems like it as one star because I am asked to rank beauty and not importance. The problem is not unimportant but I thought too much time about other moves and did not pay attention first that the knight has only one escape. p11468 b UriBlass 1852 9.5 seconds p11468 b grom43 1654 As White, before you choose 2 Ng5, you get to look at 2 g4 (no good) and 2 Bxc5 dxc5 3 Ne5 (no good). So it's not pointless. p11469 b elektrik 1392 I don't get it. Why sac the rook here? p11469 b kingz 1463 well its actually the a7 pawn that wins..look at it again, dude.. p11469 b deepsea 1305 it forces capture then queen promotion 4 teh win you n000000b p11469 b moegigo 1611 no the queen threatens "baseline mate" p11469 b chessdog 1324 i love lamp p11469 b Holy 1098 Brilliant. The queen's mate threat prevents BxRb8. p11475 w sleiman 1406 you've got to consider the sequence of the moves before you hastily go for the back row mate p11475 w drad 1651 indeed, my mouse was just about to start clicking towards the backrow mate when I stopped myself, then I started getting all nervous about f1 before I saw that the bishop was defending it and everything was fine.. p11475 w drad 1651 all in the space of 2 seconds ;) p11479 b UriBlass 1852 problem 23140 to solve 4.5 seconds. nice idea of fork against a pin. p11479 b Arkenshaw 1733 Nd2 defends p11486 w UriBlass 1852 6.6 seconds 1772.74 new record after 24650 problems used some time to check the solution so got only 0.1 rating point. p11486 w barz 1708 â—„ Position â–º r1b1r3/5pk1/p2p3p/q1pPn1p1/P1B1Pn2/1p4B1/1P1N1PPP/RQ3RK1 w - - 0 1 p11489 b BlackWaive 1551 Looks like a theme I'll need to remember. p11489 b UriBlass 1852 3.5 seconds p11489 b barz 1708 3rr1k1/p2n2p1/1pn4p/3RP3/2PN4/7P/P2B2P1/4R1K1 b - - 0 1 p11492 w stalmannen 1423 What am I missing?

And after 1...fxe4 White has the perpetual checks at best, whereas any other Black move will give White a winning position. p11495 b Holy 1098 Simultaneously safeguards the attacked piece and creates a double attack, including an attack on the enemy queen. p11495 b curiouschild 1223 nice escape p11503 w Hexalingual 1342 pawn promotion p11508 w UriBlass 1852 failure too fast played Rxd4 with the idea Qxd4 Qxc2 fxe4 Bc5 that does not work and I saw that Qxd4 Bc5 is not good but forgot it 2 plies later p11514 b joakimvitriol 1661 skewer p11517 w Holy 1098 It always seems difficult to see the piece traps. p11517 w SignoreX 1223 Beautiful problem, but one that makes me wonder yet again if more flexible time constraints that vary according to problem might improve the learning process... p11519 w underated 1374 and that was that. p11522 w OldPatzer 1054 Double attack: B(e8)c6+ checks K(h1) and threatens R(b8)xh8(Q). p11523 w DocB 1237 it goes on and on and on and oooongasem p11528 w malvar 1286 Knight sacrifice, basic deflection p11528 w raylitalo 1095 Qa7# is bad luck? p11528 w OldPatzer 1054 Mate threat wins material: 1...N(e6)xd4(P), threatens 2...N(d4)xe2(Q)+ or if 2. (Q moves), N(d4)xf3(N) followed by 3...Q(c6)xh2#. p11529 b jokim 2000 Good CTS problem p11535 b Subrosian 1658 Smothered mate! p11535 b Holy 1098 Show a few more moves. I got the problem correct, but thought that the next move was to advance the b-pawn, defending the Q from the R and winning a R. Maybe that result was overwhelming, just like the mate, so it wasn't "wrong enough" to make the smothered mate line clearly the best. p11536 w JSorel 1664 5.0 seconds p11538 b underated 1374 have been in similar end game. p11538 b MaltaCross 1155 2.Ke6 is threatening mate in 1! (This is why Crafty opts to sacrifice the rook.) p11538 b ehodge3 1325 It is mate in one, the only move is to give up the rook which delays the inevitable. p11538 b pmevans 1119 This is a sweet move! It took me a second to see it. p11539 b tjumen 1598 spent a lot of time.. p11539 b acts1631 1658 Great style. p11539 b Marcin1996 1616 nice p11539 b Alseki 1484 Good problem. p11544 b mykingislonely 1861 Problems where I have to pick a place for my king are always hard for me. :/ p11548 b shevtsjenko 1858 why does 2.Re7 not wins? p11548 b tomohawk 1833 I thought that too, but it seems that 2...Qf5 defends. p11548 b milos62 1916 I played Re7. p11548 b UriBlass 1852 19.8 seconds hesitated because the high rating and cared to calculate 2.Qxf8+ Rxf8 Re7 Qf5 did not calculate 2.Re7 p11548 b UriBlass 1852 3.4 seconds p11548 b MagicCat 1621 1.0 seconds it is really overrated p11548 b JSorel 1664 2.Re7 ? ... p11553 b wild 1305 Saw the tactic, but for some reason I thought clearing the file first (Rxf7) seemed like a good idea. p11554 w grom43 1654 The tactical theme is very nice (the queen travel to arrive at a won piece) and you must check that there are no mates. p11555 w tpollet 1651 Tour fou dame sur la même colone, le fou s'en va sur échec, il reste ? p11555 w JSorel 1664 very easy p11558 b UriBlass 1852 19.9 seconds needed to see that Kd1 is bad because of Rc1+ and did not like to guess p11566 b UriBlass 1852 2.5 seconds p11566 b UriBlass 1852 1.9 seconds p11566 b LowScore 1564 You've solved problem p11566 in 0.6 seconds.

You take the bishop, what else would you do? Moronic. p11571 b tomohawk 1833 Since the problem has a rating in the 1700s, I would guess that MANY people do something else. ;-) p11571 b smotherhubbard 1838 And you would be wrong tomohawk... but people spend about 30 seconds looking for another tactic, take the bishop eventually, and thus inflate the problem's rating. p11571 b tomohawk 1833 One of the skills that a tactician must have is to figure out when a position does NOT have a tactical solution. p11571 b Vandebent 1701 Everybody would take back immediately in all circumstances except when you say: “Watch out, this is a problem!â€� So please, get rid off this kind of nonsense. p11571 b tdemedts 1728 I completely disagree Vandebent, the great thing about CTS is exactly that it contains many problems where the solution is a "stupid" recapture. That makes it very realistic, much more than many other sites or books where you know in advance that the solution is a tactic! p11571 b barz 1708 To those who say that this is not a problem : what do you do after 2...Qxc3 ? p11576 w UriBlass 1852 7.9 seconds p11576 w Improchess 2054 Overrated problem. p11576 w jokim 2000 For me quite troublesome p11576 w barz 1708 Strange play by white. p11583 w theKnife 1671 A crushing "quiet" move. p11593 w UriBlass 1852 9.5 seconds p11594 w plopje 1678 nice p11594 w UriBlass 1852 10.8 seconds p11604 b Titan 1903 Not so difficult... p11606 w UriBlass 1852 28.5 seconds p11606 w UriBlass 1852 29.0 seconds p11610 b Carbonic 1527 Forced, but you have to see the pin. p11611 w MrDenali 1357 Ingenious ! :) p11611 w Rabatt 1256 insane! how is anyone supposed to see that ... a "stalemate threat" p11611 w ankka 1302 nice :-) p11611 w mykingislonely 1861 But I'm a 1850+ rated tactician.

Nd2 Bb4?! 5. a3 Qh4?? 6. g3. 4...Bb4 seems dubious, giving up the two bishops without justification; instead 4...Nc5, keeping White's Nd2 a little awkwardly placed, seems more normal. p11621 b UriBlass 1852 7.0 seconds defencive moves p11621 b UriBlass 1852 2.6 seconds p11623 b UriBlass 1852 problem 23168 to solve 8.8 seconds got it in the past but too slow to see the bishop. p11627 b hmpf142000 1670 too easy for 1700! p11627 b JSorel 1664 ...but I managed to fail to solve it :) p11627 b schttnsldt 1576 ho to know wheres a1 and where h8? go to hell p11627 b MagicCat 1621 i agree with you schttnsldt I fell for this trap and I thought the a-pawn (or h-pawn) has 7 more squares to go!!! p11627 b UriBlass 1852 It seems not too easy for 1700 because it is now 1713.4 It is easy to know where is a1 and where is h8 but some solvers are not experienced in it(the rule is that your pawns go to the top of the screen when the opponents pawn go to the bottom of the screen p11627 b drad 1651 imagine if you were playing a real game and suddenly couldn't remember which way around the board was ;) p11627 b rathkeltair 1694 Uri - you eejit - in chess diagrams it's usually a1 at the bottom left not h8; however here they have whoever to move at the bottom, which can be very confusing without labels otherwise a typical rook endgame skewer - useful to do p11627 b rathkeltair 1694 i meant 3 stars p11630 b pdazz 1388 need to show it further p11630 b scuba 1321 right...how is this a good play? seems to just give up a knight for nothing p11630 b scuba 1321 the play below...they can take the knight withe the bishop, so no need to expose the king via fxe6 p11630 b IaGueTe 1486 Black queen is hanging. p11630 b curiouschild 1223 discovered attack, against the queen p11632 w MaltaCross 1155 It's a mate in 4! p11633 b grom43 1654 3 Bg7+ is tempting.

For both moves, all available moves result in a draw with best play on both sides. The Crafty analysis is inaccurate, as is often the case when a computer isn't using an endgame tablebase. p11745 w Holy 1098 The problem is still here. It plays like a good problem and makes you think, but it's still flawed because of the endgame tablebase analysis. p11745 w e4e5f4 1402 The Nalimov Tablebases tell a win situation for Black, if it is played like the solution. p11750 w tpollet 1651 aTTAQUE double encore une fois. ou plutôt attaque tour + menace prise avec échec grace au clouage de f2 par l fou p11750 w UriBlass 1852 20.2 seconds not simple to see the fork(Rc1 pawn g3) p11752 b greatkid 1694 overrrrrrrrated p11752 b barz 1708 3Rr3/4q2k/2p1rn1p/Q3p1p1/2P2pP1/1P3P2/1BK4P/3R4 b - - 0 1 p11753 b OldPatzer 1054 Trapped Q: After ...Q(e4)xR(h1)- B(e2)f3 wins Q. p11753 b Holy 1098 I find it difficult to see the queen traps quickly. p11756 w Markusgoth 2122 Great problem! p11761 w MaltaCross 1155 Never underestimate a pawn's potential! p11768 w UriBlass 1852 73.6 seconds solution needs to be longer p11768 w smotherhubbard 1838 should be 1...Rh4 2.g3 Bc6+ p11768 w grom43 1654 Nah, solution shld be 1.Bg1 Rh4 2 h3 Rxh3+ 3 gxh3 Bc6+.

(1) After 2...e5 the pawn still cannot take the d4 knight, because it is pinned! (2) This tactic seems to illustrate that it is much better to push your Queen into the 'check' zone first, then to push the rook into this zone first.

I do not care about losing rating points for this problem but I care about my accuracy. 3.Qh6 is a forced mate for white based on stockfish when 3.Rxf7 is a drawing move so milos is wrong 3.Qxh6 seems to be the only winning move and the word also is not correct. p12825 b Elroch 1453 Nd3+ seems easy to overlook p12825 b Holy 1098 Subtle--need to see the opponent's knight fork to win back the seemingly loose queen. p12828 w floreatdunum 1719 funny little trap at the end! p12833 w UriBlass 1852 14.0 seconds p12833 w UriBlass 1852 2.8 seconds p12843 b UriBlass 1852 hard guessed Nf5 and even after seeing the solution it took me long time to understand that the idea of 3.Bc4 is Qxg6+ p12843 b television 1655 when i realized the threat Qxg6 .everything makes sense p12846 b tomohawk 1833 3.Bg5 is winning, too. p12846 b milos62 1916 Yeah, I played 3.Bg5. p12846 b MagicCat 1621 I did too p12846 b Zuggy 1902 me too p12846 b rathkeltair 1694 agree with tomo p12859 w Hyperbeam 1761 Not cool p12859 w floreatdunum 1719 dull p12859 w rathkeltair 1694 crap - Black is busted p12859 w mathaias 1434 Was there a point? p12861 b UriBlass 1852 1.4 seconds p12861 b television 1655 easy for 17xy p12871 b underated 1374 too many options. too few a time. p12881 b DocB 1237 very pretty and girzl and gills and fish swim and make noise and backr akrard jouh and the capoiton ofo the satar shop inerterprise coame and fuckaer chalwa p12881 b oconor 1156 DOCB, YOU HAVE A WAY WITH WORDS p12881 b neiking 1591 I agree with oconor p12882 b queenant89 1470 the problem should be 1.

Thanks. p12895 b hardcorepawn 1418 that would appear a lot in real games p12896 b MaltaCross 1155 CONTRARY to Crafty's analysis, after 6.Kf2, Black can move 6...g6, and this will not surrunder the Black rook to White's forces. Thence this tactic is most questionable. p12896 b kendal 1531 An explanation WHY ...g6 is supposedly a magical panacea is needed here, I don't see how that does anything to hold the rook, especially as it leaves the rook pinned. p12899 w Svenja 1588 Sucks because of two solutions! p12899 w drad 1651 doh, tried e2.. oh I see p12904 b joakimvitriol 1661 skewer p12907 w barz 1708 â—„ Position â–º 5r2/1b1kb1R1/p2N1p2/3PpP2/1pBR4/1Pq5/PKP3Q1/8 w - - 0 1 p12916 b davidcoote249 1019 I am a bit lost because surely black will get a quenn on there next move?? p12916 b Holy 1098 davidcoote249: 1. ...

I think the problem is underrated. Should be 2000+. BTW, if we do this problem, it's because we wamt to do better than the obvious move. This exercise exercises nothing. p14495 w milos62 1916 I agree with jokim. It took me 19sec to see that everything else looses at once. So the point here is not what, but how fast. p14497 w underated 1374 that is a tricky pattern against a very open board. p14508 w jokim 2000 It is a bit unfortunate that White plays the worst possible variation, but the continuation shows what you should have seen before playing move one... p14512 w alighieri 1341 was nice p14521 b czukay 1427 I should have seen that... p14526 b Zaphod 1274 I'd like to suggest that perhaps the bishop sacrifice should be an acceptable first move. p14526 b Subrosian 1658 Black will just take your rook then :) p14526 b Holy 1098 Excellent! It shows that a pawn that will inevitably promote is worth more than a bishop. It takes advantage of Black's inability to reach the pawn with either the king or the bishop. According to the Crafty analysis, Black is hopeless if he takes the White bishop, so White chews up Black's pawns and get a won endgame. p14528 b Holy 1098 Nice queen trap. p14530 w UriBlass 1852 5.1 seconds p14530 w tngerb 1486 Hmmm so I successfully won nothing? why not just win a pawn at least with Rxg4... p14530 w Alseki 1484 Because you are in check, and are about to lose the rook before you have any chance to play Rxg4. p14538 w Markusgoth 2122 Excellent problem!!! p14538 w UriBlass 1852 35.2 seconds Nb7 Bf4+ seemed dangerous and saw nothing wrong with Kc8 but hesitated too much p14540 b FernanDoylet 1252 nice check! p14540 b pq4pq4 1025 So many distractions in this problem it took me 10 minutes to see that the solution was a solution. p14543 b wald 1565 too easy for 1698.7 p14543 b grom43 1654 They're all too easy!

Took too long to see the mate after the queen exchange/saving of the bishop p14712 b JoshBrack 1626 i've looked at about 50 problem's RD's now, comparing them. so far every problem over 1750 rating had an RD over 8.5. all the problems with RD's under 7 had a rating less than 1600. p14737 w hmpf142000 1670 Well I found the Right move but its not enough, i think ( but nice tactic in Endgame!) p14737 w UriBlass 1852 22.0 seconds not easy to be sure about it. p14737 w UriBlass 1852 7.3 seconds p14737 w MagicCat 1621 I didn't find it p14737 w JoshBrack 1626 omg, 226 seconds of calculating and it didn't let me do more than 1 move. what a jip. are all the high rated ones gonna be boring like this? p14738 w IaGueTe 1486 Second time I play this problem! I give it a 4 now. p14740 w tomohawk 1833 Should extend solution to 6...Rxg7 in the line. p14740 w drad 1651 was so sure it'd be something like Ra8, followed by e7+ (looks again) p14740 w drad 1651 I totally agree with Tomahawk, that 6th move would fool so many people p14740 w barz 1708 8/1R6/8/2P4p/p3k2P/P1B1pb2/1P5r/5K2 w - - 0 1 p14745 b underated 1374 looks more logical to me once I muffed the first solution. Doh! p14745 b Holy 1098 Funny--my very last problem was the same theme--seemingly giving up a queen for a knight, but enabling a king-queen fork with a knight to win back the queen, thereby netting a piece--but that problem was rated about 200 points higher. p14745 b MaltaCross 1155 Two forks one after the other, both with check, win a piece. p14749 w onat 1932 overrated 2140 p14751 w OldPatzer 1054 R fork: R(g5)e5+ attacks K(e3) and Q(e6). p14761 w UriBlass 1852 6.1 seconds p14763 w UriBlass 1852 2.9 seconds p14764 w UriBlass 1852 24.6 seconds p14764 w tjumen 1598 3.8 sec p14766 w staham 1366 Nice queen trap! p14767 b MaltaCross 1155 This is quite a tricky position, and in my opinion, fully deserves its 1400+ rating. If 2...fxe6, White takes with the bishop (3.Bx36), winning another pawn WITH CHECK, and then 4.Bxd7, taking a piece. The exchange leaves White two pawns up. Crafty's main line shown hereunder, also leaves White two points ahead, after the exchange of the knight for the black rook (move 4), following the fork in move 3. So either way, White gains two points! p14767 b MaltaCross 1155 Another variation that again leaves White two points ahead, is even simpler than Crafty's main line below. After 2...Nxe5, White can simply capture: 3.Nxf8 ! p14770 w MaltaCross 1155 double (discovered) attack p14774 b UriBlass 1852 23.4 seconds p14775 w Schumi 1523 Just take the piece? p14775 w priamos 1472 ??? p14775 w Rabatt 1256 obvious move wins ... it's a "rarity" innit? why is this rated 1380 tho its more like a 800 level p14783 w sahiztac 797 greetings, why didn't my rating change when i solved my last 2 problems successfully? handle-sahiztac p14783 w suddenlysomeon 1276 Definitely underrated. p14783 w MaltaCross 1155 decoy (Qxd4) followed by a skewer.

On 2.Qe4+ or 2.Qd3 then Responses are 2...Kg7/Kg8/Kh8. If 2...Kg7/Kg8, then 3.Qg6+ wins for both choices (through queen exchange followed by promotion). If 2...Kh8, then either 3.Qa8(2.Qe4+) or 3.Qd8 (2.Qd3+) promotes the pawn. Switch the white pawn at b3 for a black one at c4, and I think you can prevent 2.d3 p14858 b pkendal 1520 Agreed. But aside from the issue of the uniqueness of the solution, this is very pretty. p14858 b Fromper 1338 Again, Qd3 needs to be an option here.

I saw that line, did not try 1...Bxf3 and found that WAS the solution with a mate afte white's second move blunder. Poor and confusing problem. p15221 w evilemperor 1383 Complete agreement with Marvol p15221 w theKnife 1671 2.Bxf3 is a defensive move. The only move that doesn't lose a piece. And it works because of the mating idea. But I agree that White blunders. p15221 w theKnife 1671 I meant : 1...Bxf3 is a defensive move. p15221 w birdeye4k 1431 I'm also agree with Marvol; white's second move 2.Rxh2 is simply a suicide. 2.Bxf3 it’s the only acceptable answer to avoid the mate. p15221 w pkendal 1520 I agree with theKnife that you are being too hard on the problem. 1....Bxf3 only works because of the mate, otherwise it fails. So they show 2. Rxh2 in order to make it more instructive; the Crafty analysis gives the stronger line. p15221 w Twinpeaks 1775 i didn´t solve this problem because 2.Rh2 was not a move in my calculation. change this problem p15221 w Sidorsky 1502 I was going to complain about the problem and give it one star. But I was wrong, and theKnife and pkendal and Crafty are right. White's second move, a blunder, does not excuse the fact that my first choice, ...Nxf3 (instead of the correct ...Bxf3)was also a blunder p15221 w mavaddat 1579 Bottom line: ...Bxf3 is correct. It's the only way to prevent losing a piece. I solved this problem in 1 plank length/c. p15221 w stevelco 1412 The best part of this problem is mavvaddat's comment about 1 plank length/c. funny. p15225 b UriBlass 1852 21.0 seconds p15225 b UriBlass 1852 8.3 seconds p15225 b floreatdunum 1719 excellent - the skewer threat hangs Black p15227 b MaltaCross 1155 Mate in 3! p15227 b BarryRR 1247 Why can't Black play KxR? p15227 b Theofrast 1341 I wish someone would ansewr BarryRR's question. p15235 w UriBlass 1852 8.5 seconds p15235 w UriBlass 1852 28.2 seconds p15246 w suddenlysomeon 1276 Drawing combination.

Crafty's own line below favours 2.Re4, which is a better move. It still wins a bishop though, thanks to 2...h5. p15338 w JoshBrack 1626 total crap dual solution. this problem should be removed. on the second move you can take the bishop with check if they take your rook you can win the rook with a won an easily won end game. it may not be as many points ahead but it's actually much easier being the only player with a piece left! crafty needs improvement! p15338 w JoshBrack 1626 crafty's solution gives an outcome of 11 to 6 points advantage but they're left with a bishop. but i went for the 6 points to 4 point advantage because i was left with the only piece and an easy pawn to win and then to queen advantage though. p15342 b UriBlass 1852 2.2 seconds memorized it without the reasoning looking at it again the reason is that other moves allow capturing the white queen for more than a rook. p15343 w underated 1374 i saw something else. but was so wrong. i like this one. p15343 w MaltaCross 1155 The c3 knight is guarding the Queen, and so cannot take the white knight at e2.

Silly of me. :-( p15819 w Improchess 2054 overrated 2005 p15829 w Boomer360 1178 Setting up a Knight fork. The white Rook has moved to g1, where, protected by the King, it has pinned the Queen on the g file. The threat is to take the Queen on the next move, with black only taking a Rook back in return. Black finds a way out of this situation. Black's Queen takes the Rook on g1 and now the black King is in check, and his only move is for the King to capture the Queen now on g1. Then black can play Knight takes the pawn on f3. This puts the King in check and simultaneously attacks the Queen on h4. As the Knight cannot be captured, the white King must move to get out of check. The next move, the white Queen is captured. The net result is black gets Queen and Rook and Pawn and white gets only Queen. The trick is to recognize the possibility of the Knight fork and see that you can force it. To get points, the key is to recognize it very quickly. p15830 b sarciness 1465 Run away! p15830 b Cesar2000 1417 haha p15831 w UriBlass 1852 4.9 seconds p15833 w underated 1374 sometimes it pays to look at the value of the puzzle to know wheather or not you need to be deep or just cheap. p15833 w KingKarrl 1163 1233? p15843 b UriBlass 1852 1.9 seconds p15843 b Raysalis 1600 miss p15843 b barz 1708 â—„ Position â–º 5k2/1R6/2P5/1p1p4/3P1P1p/4r3/6K1/8 b - - 0 1 p15845 w impromptus 1450 this is tricky p15845 w UriBlass 1852 3.0 seconds p15847 b Elroch 1453 Nice discovered attack setting up a mating net p15847 b UriBlass 1852 3.3 seconds p15853 b UriBlass 1852 26.0 seconds I was afraid of Rc2+ and spent time on looking for something better than Rxb4 p15853 b UriBlass 1852 1.2 seconds this time sure of my memory p15856 w OldPatzer 1054 Discovered attack: After ...N(c6)xd4(N); R(c4)xd4(N), Q(d5)xd4(R), if exd4(Q), then R(e7)xe2(Q). p15856 w stevie 1222 After removing the Knight, I liked b5xc6, check and Queen threat at the same time.

Hmm... p15988 b crptone 1575 Like problem p30188, white takes advantage of black's weak back rank with 1) Rd8#!! By deflecting the enemy rook from its post, white is able to achieve a beautiful mate.

But in a tournament you have to make the win for your opponent as difficult as possible. Especially, in a blitz game spotting this move quickly could make a big difference. It could be that your opponent even loses the game, because (s)he is short on time. p16164 w moegigo 1611 why not to remove some other white pawns and it wouldnt be lost for black. then the idea is cool p16164 w parmetd 1645 The endgame is dead lost. p16165 b spacecowboy 1394 There is a very similar problem to this one on the CTS server. The initial position is identical unless I am mistaken. But I don't remember which one it is. I just remember that Black's first move is 1...Bxf5 instead of 1...Nxf5. And the solution is 2.Bxf5 so that the enemy bishop cannot interpose on c8 after Ra8+. Maybe one of you geniuses can identify which problem I am thinking of. p16165 b underated 1374 I would like to take the knigh first. and thats all I have to say about that. p16165 b thingfish 1345 Taking the knight first loses!? p16171 b UriBlass 1852 simple but failed hurried to capture the knight thinking knight is more than a rook for a knight. p16171 b tjumen 1598 the rook is tastier than the knight p16172 b Holy 1098 A simple "remove-the-defender" tactic, but 2 things make it difficult to spot (for a puzzle): (1) the White pawn on h7 (you're thinking that there has to be a queening opportunity or threat there, or that you can make use of the pawn's control of g8) and (2) the move to remove the defender isn't a sacrifice. p16174 b N4PLL 1413 This one is not that obvious p16177 b underated 1374 need to twist your eyes around to see this one. p16177 b CryptorKid 1348 missed it... p16181 w UriBlass 1852 39.7 seconds p16185 w jpg785 1347 is the point of this just to draw the game? p16185 w LowScore 1564 What do you mean "just" draw? managing a draw in this position is awesome! p16185 w LaughingVulcan 1136 That is the point of it.... If it weren't for the Knight cover Black would win. But as it is, the lesson is how to suck out a draw from an otherwise lost position. p16189 b tpollet 1651 La d p16189 b tpollet 1651 deuxème essai: La dame enfermée.

Why not just retreat the queen to c7 or c8 when it's attacked? My solution here was Bxd3, winning a piece after Nxd3 Qxd3. p16324 b Fromper 1338 Am I allowed to complain about the same bad problem again when it comes up for me a second time? p16324 b pkendal 1520 Bxd3 (which I of course played as well) is not a solution here because the white king is in check. As for giving up the Queen I'm equally mystified, unless it's because Black is already two pawns down and desperately needs some kind of compensation in an unbalanced situation.

In this particular example, one TACTICAL TARGET is a piece (UNDEFENDED Black a2-bishop) while the second TACTICAL TARGET is a PIN (a TACTIC). This example is just like h4-h5!

However, this is not the best solution to this problem! [3] A better solution, in the event of Black moving 2...Qb7, is to block the white diagonal with Nd5 (3.Nd5), after having taken out the f6 Knight (which also controls d5) earlier with 2.exf6. Black may then take the moved Knight with his pawn (3.exd5). (The d5 square is being guarded by the White c4 pawn, and so the black Queen cannot move there!) However, in this case the diagonal is still blocked --- by the capturing Black pawn --- and so the mating threat can be removed with 4.Kxg2 whilst the diagonal is blocked (i.e. the Queen is not supporting the g2 Bishop). [4] In fact, White can afford to delay the Nd5 move, to move instead 3.fxe7, winning a pawn and a tempo obliging Black to reply with 3...Re8 to save his rook. The Nd5 move can then be effected on the next (4th) move. (After all, Black must first move Bh1 before being able to move Qg2++, so White may even wait for the Bh1 move before moving Nd5.) [5] If Nd5 is moved immediately on move 3, Black's mating threat is neutralised without any net material loss or gain. However, if the move 3.fxe7 is interposed, White wins a piece, for the cost of a pawn (since Black may eventually take ...Rxe7 after having moved ...Re8). p17106 w UriBlass 1852 16.2 seconds p17112 w Holy 1098 Nice. 3.5 stars. p17119 w UriBlass 1852 6.9 seconds p17119 w UriBlass 1852 6.7 seconds p17120 w pinkerton 1434 This move nulls a lot of White tries combining threats and defense. p17120 w grom43 1654 This move seems forced.

Blacks Knight has just moved and threatened the white Queen. The immediate impulse might be to move the Queen out of danger, but there is a better plan. White moves his Knight to h6. This puts the black King in check, so white's Queen is safe, at least for one move. Black can capture the Knight with the pawn on g7, or move the King out of check. The only space available to move the King to is h8. Kf7 still leaves the King in check, and the other spaces are occupied by his own men. Whether the King moves to h8 or the pawn captures the Knight, white captures the Rook on f8 with his Queen, and black King cannot escape check. p18318 b Holy 1098 Nice "remove the guard" problem p18323 b floreatdunum 1719 Crap p18323 b jokim 2000 Silly :-) p18323 b RedBeetle 1508 yeah! great!

I guess this was some sort of suggested improvement for Kasparov, as he lost the game in question. p18508 w Exir 1281 This isn't a very imaginative problem p18508 w MaltaCross 1155 The line discovered by Crafty (given hereunder) is very interesting: Black captures the Queen (at the cost of the Knight) after a play of six moves. p18508 w memo 1570 For this poor problem, the tactician never has to prove accurate analysis. Seeking a perpetual, seeking a mating net, or actually finding the win of the queen. Patzer sees check, gives a check. p18516 b schttn 1507 great mechanism^^ p18516 b floreatdunum 1719 typical combination of rook and knight against king on the back rank, particularly common in the endgame, nice to rehearse p18516 b plopje 1678 nice p18516 b grom43 1654 Agree with floreatdunum; typical and good to see again. p18516 b UriBlass 1852 it is clear that white needs a perpetual check because after Rf7+ and Rxf6 the c3 pawn is too dangerous p18516 b memo 1570 Yep, that's an example of Nimzovitch's Drawing Mechanism, from 'My System'. p18516 b LowScore 1564 awesome p18518 b dfeuer 1219 Huh?

White can immediately capture the bishop, but it's hard to see how to proceed from there. p18518 b disasterion 1494 2. Qh5 Bh6 3. Qxh6 and the only move black has that avoids mate is 3 ... Qxg5 losing the Q p18518 b zenchess 1612 dfeur if you can't see how such an obvious position could be won for white, i suggest you dont post comments as you're obviously a very weak chess player, no offense p18518 b Markusgoth 2122 It takes time to solve this... p18518 b spacecowboy 1394 Hey zenchess, the fact that dfeur was struggling to understand this problem is a good reason for him to post a comment so that another tactician, such as disasterion, can explain the problem to dfeuer. As we walk the path of life in which we develop increasing competencies, we will develop beyond others. Indeed, we encounter countless disparities in life. One of the tasks that life presents us is to develop tolerance for nubes. p18518 b hmpf142000 1670 your Point! p18518 b MaltaCross 1155 White is losing. With this tactic White can at least secure a draw. p18519 b OldPatzer 1054 N fork: Ng7+ forks K and R(e6), thwarting R(e6)xf6(R) p18520 w levkipos 1386 fork p18520 w Holy 1098 Capturing the knight both wins the piece (eventually) and removes the guard of the square required for the fork, to win back the very queen that was guarding the square! p18520 w JacobTomlinson 1263 Free knight p18520 w JoshBrack 1626 can some one please tell me what the f is wrong with 1. Bc5 for black? i mean, it wins a piece at least too doesn't it? i undestand the queen sac is more showy, but sheesh, this is just silly... p18522 w joakimvitriol 1661 simple pin p18523 b MaltaCross 1155 Besides the rook capture, Rg7+ also pushes the enemy King into the e-file, therefore the Rook capture can proceed before the King has time to fork the bishop and knight. p18525 b suddenlysomeon 1276 Nice endgame push. The knight cannot be dislodged and the pawn cannot promote. p18528 w HateYou 1627 phew p18528 w Jonathanzzz 1910 Too high rated for a mate in 1 p18531 w Kacparov 2002 blundered in the last move - played Kb6... p18536 b UriBlass 1852 11.0 seconds p18546 b OldPatzer 1054 N fork: N(d5)f6+ forks K(g8) and Q(e8).

Only up to understanding that Rfe1+ wins a bishop. p18576 w UriBlass 1852 2.2 seconds remember that taking the pawn lead to losing the game so even did not calculate it now p18576 w grom43 1654 tomohawk has a point: after Kf6, Be5+ will win the Bg7, so taking the pawn is wrong. p18585 b OldPatzer 1054 Q fork: Q(d5)xe5+ forks K(e8) and R(h8). p18586 b avilovi 1552 Extend the solution, it is not obvious p18586 b smotherhubbard 1838 Best is 2.Nd7+ Ke6 3.Nb6 Rd8 4.Kc5, but also easily winning is 2.Nd7+ Ke6 3.Rxd5 Rd8 4.Kc5 Rxd7 5.Rxd7 Kxd7 6.Kd5 etc. So I'm not sure extending the solution would help, but I don't like the problem. p18587 b Kacparov 2002 http://chess.emrald.net/chess.php?rand=589234625 p18587 b Kacparov 2002 sorry for that link down there, I got it there accidently p18591 w zant 1768 it seems that this problem shouldn't have a rook on f1! p18591 w jokim 2000 It seems that zant didn't understand the solution p18597 b underated 1374 simple but tough to beat. nice move p18604 b UriBlass 1852 13.8 seconds too slow in seeing the fork because thought how to promote the pawn p18606 w joakimvitriol 1661 Two knights attack forking square.

Is this optical illusion, or I was just sleepy? p18797 w MaltaCross 1155 Another incredible Queen fork. p18802 w underated 1374 I kept on seeing pressure on the exposed queen as a stronger option. p18802 w MaltaCross 1155 A fork combined with the exploitation of TWO pinned pieces! p18802 w dktransform 1479 funny how you have to think so hard for the answer, and half a year latter, you DON"T remember the answer (but know you have seen it, worked thru it) AND can quickly calculate the correct move, not from memory, but because your chess muscles have truly grown... evidence from oneself to oneself! p18804 w MaltaCross 1155 exploitation of pinned pawn p18805 w Fred 1456 What is the advantage of giving check first? Taking the Rook would leave all other options open? p18805 w Holy 1098 If you take the R immediately, White follows with 2 Bc4+, winning your R in return. You need a tempo to get your R away first. p18805 w TheBlackKnight 1542 A bit too tough for 1421 I think p18805 w Hexalingual 1342 Zwischenzug p18805 w wild 1305 great problem. Check gets rooks out of trouble. I got it wrong this time, but never again. p18805 w wild 1305 got it wrong again. p18805 w Leucky 1538 lol @ wild Any serious player should see the fork when thinking about the immediate capture.

I think that I must be missing the trick. p18812 b EricQc 1142 No tactic! p18819 b Hyperbeam 1761 Doesnt 2. exf6 also win? black loses the queen or gets mated. p18819 b merendera 1428 2.exf6 is met by Txd1 p18830 b floreatdunum 1719 Amongst all of the lowest rated problems, this is the only interesting one, with a skewer, the others are all bank rankers or a moronic recapture. p18838 b joakimvitriol 1661 trap p18839 b UriBlass 1852 played fxe4 and missed the threat Bxg7 thought about Nxe6 but decided that fxe4 is simpler p18845 w JSorel 1664 YES!!

Qxd3 2. Qxf7+ Kh6 3. h4!! forces black to play accurately for a draw: 3. ... Qxf1+! 4. Kh2 Qxg2+! 5. Kxg2 Rxf2+ 6. Qxf2 Rxf2+ 7. Kxf2 Kh5 =. Except for the last move (too close) the problem could be extended this way. Or it could be extended along tomohawk's line (though I'm afraid I always disagree with his 'should'). p18880 b UriBlass 1852 5.0 seconds p18881 b Filemon 1078 I don't think that your solution to this problem gave the best response of Black to Re1+. Surely the best response of black to Re1+ should have been Ne4 instead of Kd8 as proposed by your solution? Because of this, I was reluctant to play Re1+. Do you agree? p18881 b tomohawk 1833 Isn't Rb4 strong there, Filemon? p18881 b MMan 1255 Uhhh, 1...Ne4 sucks after 2.Rd5 (tho 2.Rb4,Qd6 3.Rbxe4+, kicks ass too). Point being that after 2.Rd5, if black moves his queen (say 2...Qf6 or 2...Qf2) then 3.Rxe4+ forces mate. Probably best is 2.Rd5,Rad8 3.Rxd4,Rxd4 and after 4.Qe3 it's all lost for black. If you don't get it, go get an engine to break it down for you: you're already on a computer. p18883 w OldPatzer 1054 Stalemate: if Bxg6(B), stalemate. p18883 w mathaias 1434 very subtle. while i was solving that puzzle, i must have looked at that position for 5 minutes before i nderstood what was happening! p18883 w mangy1723 1242 i hate stalemates p18885 b dwnshi 1559 great big fat idea p18885 b jokim 2000 Simple move, but the eyes must "scan" a lot of squares. p18885 b MagicCat 1621 I failed so I am an idiot p18886 b theKnife 1671 Nice (but line should continue). p18898 b rumapina 1748 What about QA8 and RF7?

Who can fail here? p18899 w ruylopez 2034 lol 'find the legal move' p18899 w Dieter 1676 only one move?! good for my elo, but really stupid problem. p18899 w UriBlass 1852 5.3 seconds checked to be sure only one legal move p18899 w Leucky 1538 You could ignore the check and try to checkmate or you can overlook the queen on b2 and move the king into check. Not so easy to see fast, that there is only one legal move. p18899 w Garryback 1581 boring p18899 w Vandebent 1701 This is what problemists call a no-brainer. p18899 w sleiman 1406 and it's this much highly rated (now at 1658) because most would just play an illegal move. p18899 w UriBlass 1852 sleiman,we have no statistics about what most are going to do. It is also possible that most people use a long time and solve the problem correctly. p18899 w jyt230 1507 Keeps people honest p18899 w mykingislonely 1861 To jyt230: "Keeps people honest" is why recapture problems are here (even though I don't like those). I don't see honesty is a factor here. 'I can't handle the truth that there is only one move?'... well... These problems shouldn't be here because in a tournament game, we are allowed to take back illegal moves. p18899 w LowScore 1564 Illegal moves lose the game in blitz tournaments, so it's good practice to spot the only legal move. p18899 w AlexeiD 1600 this one makes me sad panda p18899 w television 1655 i dont understand the purpose of this problem.

Heavy pieces on the back rank (Black g8-rook) do not control squares on the file (g7-square) or diagonals if they must meet threats to the back rank. p19433 b notyetagm 1467 2 Rf7xBg7! wins a piece and Black cannot recapture with 2 ...

Is it instructive, should it really even be considered a "tactic" (even if it technically qualifies)? p19455 b MaltaCross 1155 A fork exploiting a pinned pawn. p19457 w MaltaCross 1155 Removal of the opponent's defender (whilst keeping your own defender in place :-) p19458 b vjgreen 1254 Maybe I simply don't appreciate some aspect of this problem, but I don't see why it is rated as high as it is. p19458 b Fromper 1338 I'm with vjgreen on this one.

You're still losing. For a second I thought Crafty's analysis was 2 ...Qb3+ led to mate in 7, then realized it leads to being mated.

Those who don't understand should go to the bulletin board and read the posts by JoeLag and SveJoe on August 24, 2005. p19596 b blarn 1344 Reproducing the posts here, since it looks like the message board no longer goes back so far: ==================== Joe Lag on 24 August 2005 ==================== Hi! Problems which aren't problems: The last few days I complained about some problems which imho aren't problems at all - due to one of the following reasons: 1. There is only 1 legal move (i.e. p38267) 2. The solution is a simple and obvious recapture. As I said: Imho these are neither problems nor tactics. After some consideration I found one argument to keep them in the database: If you recognize such a situation very fast you accomplished a good performance nevertheless. I will stop complaining from now on until I learned more about the public opinion regarding this matter. N.B.: Great site ... and the time control should remain as it is now. CU, Joe ==================== SveJoe on 24 August 2005 ==================== Hi JoeLag! That is exactly the reason not to suspend such problems having slipped through our filters. Following this track there is an interesting excotic proposal by HocusPocus: Merge let's say 10% of pure non tactical positions and add a " Not a problem, just make a rational move!" button. This eases the a priory bias of knowing about the existance of something special in every problem. p19596 b jdmce2002 1255 And there is nothing simple about this capture. There are too choices, and one loses a piece. Under time pressure it would be east to make the wrong choice. p19597 b UriBlass 1852 Problem 23387 to solve 9.1 seconds Not the first time that I got it but took time to remember it. p19597 b theKnife 1671 A very hard-to-find switchback to the original square. p19600 b mike1 1790 Qe8+ Rxe8.

This puzzle in particular is too misleading with the Black King at the other end of the board. p19603 w wild 1305 the orientation is always relative to which color pieces you are playing. so if you're moving a white piece, a-file is left. p19603 w amyii 1354 and there are 2 little black or white square blinking at the side of the board p19603 w mtracey 1552 Even when you know which way you are going I find positions like these disorienting, I think because I am used to the kings as a reference point. p19608 w MagicCat 1621 very nice p19611 b OldPatzer 1054 Discovered attack: 2...Nxb4(N) allows 3.Rxd7(B). p19614 b MagicCat 1621 You've solved problem p19614 in 1.7 seconds.

The winning line for White is even shown by Crafty, but in a "sideline" of the analysis. I suppose you could argue that Black is lost in this position, and so 2...Qxh4+ is the "best" move since it allows White to blunder into a not-so-obvious draw, but that's not the standard set by the other problems on this site.

It should also be noted that in the right line 2.Nxd5 an immediate 2...Bxg5 does not help since White can play 3.Nxb4. p20385 b notyetagm 1467 MAGNUS CARLSEN THEOREM: overworked pieces (Black d7-rook) do -not- defend squares (g7-checking square, 2 Bb2xg7+!) p20385 b UriBlass 1852 19.8 seconds p20390 b waaek 1120 I disagree with dwal. The problem requires you to see far enough to make sure you can stop the checks eventually. p20402 b UriBlass 1852 1.5 seconds very hard problem that fortunately easy to memorize and memorization of the problem is probably the reason for the rating that is not very high. p20402 b UriBlass 1852 1.2 seconds p20406 w Vapor20 1358 Nice. p20413 b joakimvitriol 1661 there are 3 safe checks not one lol p20421 b UriBlass 1852 problem 23462 to solve 10.2 seconds nice sacrifice p20421 b drad 1651 took me a while, at first I was thinking of deflecting black's queen off the diagonal until I saw that lead nowhere. p20422 b UriBlass 1852 17.1 seconds p20422 b JSorel 1664 4.2 seconds, sorry Uri :-) p20422 b mykingislonely 1861 Why do u guys put the time you solved it in? p20422 b Garryback 1581 Uri brought forward the argument that it is not exlicitly forbidden. When everybody does what is not forbidden we will live in chaos. From time to time it is helpful to think on your own before acting in this totally stupid manner. p20427 w tomohawk 1833 Player should have to play more moves in solution. p20427 w JSorel 1664 I agree with tomohawk p20427 w floreatdunum 1719 I agree with tomo p20427 w rathkeltair 1694 I agree with thawk; solution left in the middle of nowhere p20433 b theStig 1505 White is worse anyway p20439 b palindrome 1658 Tricky.

So the difficulty for the tactician is the pattern recognition within the limited time frame of a CTS problem. So IMO, the dominant reason that problem 20445 is rated as high as nearly 1700 is because it has an uncommon theme. Tacticians are in the habit of looking to find offensive plans instead of defensive plans. p20445 b wald 1565 again one of those: find the only move which does not instantly loose p20446 b barz 1708 1r1k3r/1p1b1p1p/pN2p3/P1p1n1p1/4P3/8/1PPN1PPP/2KR3R b - - 0 1 p20448 b Mclintock45 1003 I got it right, why say bad luck p20450 b tacticaldeep 1821 it is an good problem p20450 b MagicCat 1621 yes tacticaldeep p20450 b Pinsu 1601 I think there are another solution possible. p20465 b MaltaCross 1155 Very nice checkmate! p20465 b CryptorKid 1348 nice p20472 b Alseki 1484 Pretty neat. p20475 w UriBlass 1852 3.3 seconds p20475 w barz 1708 The idea is to follow with Bxf3. p20481 w pkendal 1520 nice. p20481 w grom43 1654 Almost played ...Rg2+ first... p20481 w JoshBrack 1626 "You've solved problem p20481 in 13.1 seconds.

Nice problem. p20502 w ChessPlayer56 1801 4.0 seconds...overrated§? p20504 b MaltaCross 1155 This sets up an exchange of the White queen for the two Black Rooks, leaving White with a material gain from the exchange. p20505 b SmokenFlames 1418 Clasic p20511 w UriBlass 1852 26.2 seconds p20511 w UriBlass 1852 23.5 seconds p20511 w barz 1708 â—„ Position â–º 2rr2k1/pb1nqpp1/1p2pn1p/8/2BP3B/P2Q1PN1/1P4PP/R3R1K1 w - - 0 1 p20517 b themagician 1543 1.2 seconds p20520 b OldPatzer 1054 Trapped Q: After N(c3)a4, Q(b2) is lost. p20525 b UriBlass 1852 1.9 seconds got it in the past p20525 b drad 1651 the moves following the tactic are interesting too p20525 b memo 1570 Crafty continuation notwithstanding, most players would win Q for R with 4.Re8+ or 4.Rd6+ p20531 w UriBlass 1852 12.9 seconds p20531 w Kacparov 2002 6.3 seconds, haven't seen Nxc3 Bc5 p20535 w carlos2 1591 what ever we play posituion is lost p20535 w floreatdunum 1719 agree with tomo - good save by Black p20535 w UriBlass 1852 5.6 seconds got it in the past but was not sure p20539 w sarciness 1465 Maybe this is as highly rated as it is becasue backwards moving bishops are hard to spot? p20541 b underated 1374 good points.. p20549 w Holy 1098 Needs to go at least 1-2 more moves. Another unavoidable example of a problem that would be rated much higher, except for the fact that the correct first move is the most obvious check, which many patzers play without thinking. p20554 w Holy 1098 Good endgame problem. p20554 w Holy 1098 Even better than I remembered it. Moving the king or pawn toward the queening square guarantees promotion, but you are racing against White's pawns. Moving the king gives White the chance to catch up in the race. Moving the pawn wins the race. If White moves his king to attempt to stop the e-pawn, he has just lost a tempo, which Black can use to move his king. The threat to promote the e-pawn must be created immediately. p20554 w MaltaCross 1155 It's a race between pawns. Good point, Holy. p20554 w rudyard 1364 Learnt somehing with this one p20558 b chris2001 1747 g3 also completly winning -- not good p20558 b UriBlass 1852 problem 23036 to solve 2.5 seconds got it in the past p20558 b john2001plus 1562 Yes, I chose g3 also. p20558 b sarciness 1465 Kh3 is clearly the best choice. p20558 b justwar85 1473 can't play G3, king is in check p20558 b joakimvitriol 1661 8/8/4PQ2/6Pk/pp6/2q5/P5PK/8 b - - 0 1 p20558 b polgary 1530 1....

No problem, no matter how flawed, is ever removed. p20637 w Jason1083 1614 As noted several times before, Rf6 p20637 w MagicCat 1621 yes there are two solutions but one of them (d2) is much better than the other. It is mate or promotion that will lead to mate. p20637 w drad 1651 I agree with most people on this one, the difference between -4.4 and -12.8 is trivial. Both are crushing wins. p20637 w UriBlass 1852 Why the low rating of 1661.8 for this problem? This problem should get higher rating because many people play Rf6 Uri p20637 w drad 1651 played Rf6 again for the 12th time in a row.. I've tried to memorize this puzzle in the past, but my Rf6 instincts are unstoppable it seems.

After 1...Qc7+ this isn't a problem. p20640 w UriBlass 1852 13.2 seconds Qb8+ does not prevent Qg7 mate but I guess that most solvers do not think and guess Qc7 so it get relatively low rating. p20640 w tjumen 1598 I always think about the difference when there are more than one choice. It cost time though. Maybe I should guess more ) p20640 w MagicCat 1621 2.8 secs p20640 w MagicCat 1621 I guess, I don't think :) p20643 b MaltaCross 1155 A discovered attack tactic that is not easy to see. p20645 w Kobes 1005 In p20645 Black (the tactician) seems dead lost after 1. Bxg6 Ra1+ 2. Kg2 Ra2+ 3. Bf2. If so, the problem is just how to postpone the inevitable, which is unsatisfying. Am I missing something? -- Kobes p20645 w clueless 1482 I agree with Kobes' observation. No satisfaction. Black is lost and can only postpone the inevitable. p20645 w Holy 1098 No. Black wins the Q for the R. White's R cannot give checkmate on h8 after that (no protection from Q). White B cannot deliver mate from h7 as Black K escapes to h8 behind the White B. Black avoids checkmate and has large material advantage. p20656 b Charzard 1425 It might be a little to easy well its really between easy and mediem p20660 w Holy 1098 Great problem! The check gains a tempo AND protects the R, which would be exposed after taking the N. p20660 w chessidiot 1219 Agreed.

Qe7+ Kh6 transposes into the game. So it seems Black wins anyway. Yet White secures a draw by 3. Qc7+! (instead of 3. Qe7+) - from c7, the Queen still watches the f4 square so 3. ...

Beautiful puzzle! Though, in a puzzle there is no way to know if castling is still legal. p20962 b Markusgoth 2122 Gorgeous! I didn't even think castling is an option here! Applause! p20962 b 10001xx 1358 Actually i think castling is an illegal move here.... The web master should perhaps control it. p20962 b mostro 1358 castling is an illegal move p20962 b JamesBJames 1657 I'm pretty sure this is legal. Let's go over the rules for castling (Taken from Wikipedia): 1. The player must never have moved the king. (This can't be verified, but in this case, it's assumed) 2. The player must never have moved the rook involved in castling. (Same as before) 3. There must be no pieces between the king and the rook. (True) 4. The king may not currently be in check. (True) 5. The king cannot pass through squares that are under attack by enemy pieces. (True, and probably the one that's confusing most of you. The rook moves through a2, but the king does not move through an attacked square) 6. As with any move, castling is illegal if it would place the king in check. (True) 7. The king and the rook must be on the same rank.[1] (True) Since these seven rules hold true, castling is legal. Good puzzle. p20962 b JamesBJames 1657 Eh, it screwed up my spacing, but oh well. p20962 b Fromper 1338 Oddly, I spotted this one instantly. For a patzer like me, that's weird. :) p20962 b gbekker 1383 Nice one! PS: Yes, Castling IS legal in this position. International Arbiter Gary Bekker. p20962 b martynspeck 1289 That's just mean. p20962 b Nuart 1359 Splendid! p20962 b pincopal 1255 beautiful problem, also I thought like many others that castling was illegal but in fact it is not. p20962 b ajotatxe 1405 Castling here may be legal, since the tower (or any other black piece) does not cover any of the squares in the King's path. p20962 b charlie49 1407 Very good. A little bit of lateral thinking works wonders p20962 b kanon8 1243 you can't do O-O-O IT's ilegal move I play the other move. PLease change the problem p20962 b tjumen 1598 i see people like to discuss things, so here's my 2 cents. Castling is legal. p20962 b LowScore 1564 "Whenever you can castle with check, do it." - GM Yasser Seirawan p20962 b Jonathanzzz 1910 Since it is a problem, we always assume that the king and rook has never moved (in they are on their original squares), so castling is legal in this case. This problem is also quite popular, seen it before somewhere (that isn't cts). p20962 b jdmce2002 1255 pffff, most certainly illegal! glad I missed this one :) p20966 b UriBlass 1852 4.6 seconds not hard thought to play Qa6+ but saw Qb7 p20966 b UriBlass 1852 6.7 seconds p20968 w UriBlass 1852 1.5 seconds remember it from the past p20968 w UriBlass 1852 4.3 seconds p20968 w barz 1708 1rb1k2r/2qpbppp/p3pn2/2p5/N1PQP3/4B3/PP2BPPP/R4RK1 w k - 0 1 p20970 w wald 1565 what's this? according to crafty, black is still loosing p20970 w floreatdunum 1719 correct, but a bit silly really p20970 w UriBlass 1852 18.2 seconds did not believe that it can be so simple so used my time p20970 w UriBlass 1852 9.7 seconds was not sure that I remember it correctly p20970 w tjumen 1598 I agree with wald.

Next white move is forced (Kd5) and then the piece that black was trying to win can be captured by Rxf7...that was the plan of Qf5+ so I don't see the need for actually having to play out the capture. p20980 w cheetah7 1492 I wouldnt get it. p20980 w mburch1974 1481 if you know anything about double checks its not too hard to see. p20980 w palindrome 1658 one of the only one Iowaplayer has missed.

My Shredder rates it as second line with a value of +6.9 at 19 ply. 2.Rf3 is the first line with +22.0 ay 13 ply. In reality there is no difference between +6.9 and +22.0. Both evaluations have identical meaning, which is: "black wins". p21242 w smotherhubbard 1838 Oooh, a subproblem! 1...Qb6 (my move) 2.Qe8+ Nf8 3.Rh8+ Bxh8 4.Rxh8+ Kxh8 5.Qxf8+ Kh7 6.Ng5 mate. p21245 w DocB 1237 took 10 minutes on this because it said my right answer was wrong.

Kxe3 is not White's best move, but it is the only one that demonstrates the point of Black's move clearly. p21370 w JoshBrack 1626 damn that shit racked my brain and it's only 1370. i must be high. :( p21378 b UriBlass 1852 15.1 seconds p21378 b Arkenshaw 1733 1.

And does it really make a difference if Qxd5+ rather thsn Qxg5+? Can't be bothered to analyse it. What I do know is that half the people guess the right check, half the people guess the wrong check. No one actually sees it the whole way through. Look at the variation given by Crafty below: 12 moves, for Pete's sake! GET RID. p21417 b UriBlass 1852 I disagree. No need to see the whole way through. You only need to see that after Qxd5+ Kh8 there are no checks for white to decide that Qxd5+ is not good. p21417 b joakimvitriol 1661 4r1k1/p6p/b7/2ppq1p1/2p5/2P5/PP1QN1PP/3R2K1 b - - 0 1 p21417 b joakimvitriol 1661 yes, one check leads to perpetual and another doesn't p21418 b theKnife 1671 The "Blackburne mate". p21418 b joakimvitriol 1661 forgot about this BBN pattern p21418 b rathkeltair 1694 An example of Blackburne's mate p21419 b UriBlass 1852 4.6 seconds fork 2 bishops and escape with the knight p21419 b UriBlass 1852 2.9 seconds p21421 b MaltaCross 1155 tricky removal of the guard problem p21425 b hardcorepawn 1418 so, don't take the knight and lose the queen? rubbish p21425 b Sidorsky 1502 I have to agree with hardcorepawn, but I also have to admit that I missed the fact that my queen was en prise. My only consolation is that I must not be alone, insofar as the problem is rated 1413 p21425 b Leucky 1538 Very easy task. The knight forks king and queen and there is nothing else (e. g. mate) to concider, so Rxe2 is forced. p21443 w UriBlass 1852 2.1 seconds the first moves that I thought about so I am surprised by the 1941.4 rating points p21443 w Jonathanzzz 1910 I'm surprised about how high the rating is too. p21448 w UriBlass 1852 13.0 seconds nned to see Rxa2 Qxe5 and the fact that white threats Qg7 mate p21450 b JoshBrack 1626 double checks for the win! p21450 b Baully 1328 neat problem! p21450 b Suizo 1631 Sf6? p21454 b d4d5c4 1559 Die Dame dringt in die geschwächte Königsstellung ein und lässt den König nicht mehr entkommen. p21456 w tomohawk 1833 Nice.

Might work in blitz play, though. p21477 w wald 1565 only legal move is the solution, so unless you make a mouse click, you cannot fail to solve this one! p21477 w Leucky 1538 Its okay. The problem is here to check the facts fast. Its seems that many players don't solve this kind of problem fast. Otherwise this problem would't have this rating. p21478 b UriBlass 1852 7.5 seconds p21480 b suddenlysomeon 1276 Holy shit, there was a queen in there! p21486 b notyetagm 1467 MAKE A BIGGER THREAT: 2 c7-c8=Q! ignores threatened ...

Rh7? can't see it, but haven't started Fritz... p21529 b grom43 1654 I took 1 Rh7+ because it wins, but already in back of my mind thought 1 Qh2 would work. 1 Qh2 is far superior move, so if you are quick... p21529 b LowScore 1564 While it's true that both 2.Rh7+ and 2.a4 are winning moves, the problem is about the mate in 3 after 2.Qh2! I think it's quite okay to count inferior winning moves as wrong answers for a "mate in three" problem. p21530 b Hyperbeam 1761 nice one p21530 b kendal 1531 Did that feel like tic tac toe to anybody else? p21532 w underated 1374 bonus points for that one. p21532 w Fromper 1338 This puzzle should definitely be played out for another couple of moves. p21532 w IaGueTe 1486 More moves please! p21532 w guidovanhout 1242 more moves p21534 w EngrStudent 1315 This is not challenging.

What else would you play? Take on h2 with the knight? Don't be a numpty. GET RID of this cloacal emanation. p21670 b benmgood 1751 The point is not to choose between Nxh2 and Kh1, it is to choose between Kf1 and Kh1. Kf1 allows black to escape with both bishops, Kh1 does not. p21670 b ealster2004 1632 Well Nxh2 is not quite as bad as it looks, although still worse than Kf1 and Kh1 because Nxd5 and some might think that you can get 3 pieces and initiative for queen. p21670 b UriBlass 1852 14.1 seconds should be longer and Bd6 Nxd5 should be included p21670 b drad 1651 What happens after 2.Kh1 Bxf3 3.Qxf3 Be6?

I still don't like the problem--in a real game obvious moves should be double-checked, but here it costs rating points. p21670 b grom43 1654 2 Nxh2 is as bad as it looks (you only get 2 pieces for the queen). 2 Kf1 is OK. 2 Kh1 wins a piece (keeps double on h2 while threat Nd5 waits). Not so simple as to be called pure crap, though. p21670 b JoshBrack 1626 that really sucks that they didn't bother to analyze Nxh2 with crafty. :( I looked at it for a long time and decided it was winning and now I gotta either look again or throw it on chessmaster or just try to memorize the solution or just keep missing it. p21673 b floreatdunum 1719 Comical! p21673 b DanielD 1783 why is this problem rated so low?? p21673 b UriBlass 1852 12.5 seconds I agree with DanielD and the problem should get higher rating p21673 b pinguino 1600 It´s not so easy! p21673 b grom43 1654 excellent p21676 b PeterYpma 1665 This is not wat I expect by 1638... p21676 b floreatdunum 1719 whaaa??? p21676 b UriBlass 1852 3.7 seconds rating is now 1640.3 I think it could be also 1240.3 without changing people probably expect something hard at 1640.3 so they think and they do not expect something hard at 1240.3 so they do not think. p21676 b drad 1651 no there's really only 2 possible things that people would try.. and Qf3 fails to the knight fork which low rated people miss at high speed so it's good p21676 b drad 1651 sorry make that Qf4 p21676 b mykingislonely 1861 I feel like i'm at the wrong site.

[2] If White replies 2.e7, Black can reply with 2...Bxe7, leading to 3.Qxe7, and winning the Black Bishop. Else Black can reply with 2...Bxe5 (capturing the Queen), leading to 3.e7 exd8 = Q, which will also win the Black Bishop. [3] White may opt to move his Queen to safety rather than sacrifice her. However all the squares that the White Queen can potentially move to (excepting the d5, e3 and e2 squares), are directly controlled by Black's forces,. [4] Moreover, 2.Qd5 or 2.Qe2 invites 2...Nf4, forking White's Queen and advanced pawn. This will oblige the White Queen to move again to evade capture, and thenceforth relinquish her support of the e6 advanced pawn. Then after 3...Re8, White's advanced pawn is lost. So 2.Qe3 is the only remaining viable option. [4] However, with 2.Qe3, White does not win a piece, and so the 2.e7 line with the QUEEN SACRIFICE remains the better alternative. p21784 w biike 1777 genius p21786 b Leucky 1538 an usual queen fork. p21787 b dwnshi 1559 wHAt thE HeCK......................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................??????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! p21790 b gabe487 1084 Is this what they call the X-Ray tactic? p21790 b snakehead 1475 It looks like an x-ray, but it's actually a remove-the-defender. p21790 b snakehead 1475 See the end of 34412 for an x-ray. p21796 w JSorel 1664 the other side... p21800 w Sparfy 1253 awesome p21800 w UriBlass 1852 problem 23240 to solve 3.4 seconds p21801 b deacon 1115 Nice, I hate it when I don't see that I'm in check. p21801 b MaltaCross 1155 Adding a fourth move would make this problem trickier, since only 4.Qg7 would deny Black from drawing the game. p21806 b UriBlass 1852 21.4 seconds p21806 b joakimvitriol 1661 rank attack p21809 b kwanpin 1752 Re8+ Qxe8 Qxf6 Kg8 , not mate p21809 b grom43 1654 Right, because of the Rb7. p21824 w JSorel 1664 You've solved problem p21824 in 0.7 seconds.

Garryback p22346 w tpollet 1651 L'idée du sacrifice, mis à part la mise à nu du roi, est aussi de faire jouer toutes les pièces. p22346 w Chessdoom 1586 great one, i don't understand what the francheman says :-) p22346 w Hyperbeam 1761 nice effect...very pleasing the way the pieces join the fight. p22346 w UriBlass 1852 2.2 seconds p22346 w grom43 1654 The idea of the sacrifice, in addition to denuding the king, is also to play all the pieces. p22346 w LowScore 1564 Die Idee hinter dem Opfer ist neben der Freilegung des Königs auch das Mitspielen sämtlicher Figuren. p22348 w joakimvitriol 1661 zwischenzug p22353 b UriBlass 1852 25.7 seconds more moves are needed p22353 b smotherhubbard 1838 Black queen is trapped--only move is Qd5, which allows Ne7+ p22354 b UriBlass 1852 played a6 that may be also winning and I will analyze it later. p22354 b UriBlass 1852 a6 is not good enough black reply Qf4 and white cannot promote the pawn because of perpetual check threat so the problem is ok. p22354 b UriBlass 1852 45.7 seconds p22354 b milos62 1916 UriBlass, look at Crafty's analysis below. 2.a6 is also very good (but Rh3 wins at once) p22354 b UriBlass 1852 milos62 I do not need to look at Crafty's analysis There are better engines than Crafty Rybka3 suggests after 2.a6 the move 2...Qf4 with score of only +0.99 for white at depth 14. It means that 2.a5 is clearly not a winning move It is not a perpetual check but 2...Qf4 threats perpetual check so white cannot play 3.a7 to win. p22364 b UriBlass 1852 9.1 seconds p22364 b JoshBrack 1626 13.1 p22365 b john2001plus 1562 For some reason hard for me to see. Problem is that I was focussed on the opponent's king. p22365 b bumbly 1561 not 1635 problem at all p22365 b dwnshi 1559 HELLO THAT WAS EASY> p22368 w UriBlass 1852 18.5 seconds p22373 w KlausE 1204 This is one of the problems where the rating of the problem is the biggest problem. Would it have a rating below 1200 I'd capture the queen before even starting to think. But as it goes with a 1450 rating you start thinking that there should be some elaborate move and so wasting your time :-( p22373 w QuickFire 1582 Play the board not the rating -- I waste time in real games too. p22375 w pinkerton 1434 Overrated. Please revise. p22375 w Hyperbeam 1761 Missed it... its a nice one. p22375 w UriBlass 1852 I do not see why people say overrated about sacrifices non sacrifices are more easy to find and the natural moves to think about are moves like Nh4 p22375 w UriBlass 1852 thinking about it again it is easy to see that Nh4 lose to Qxd4+ so after seeing that black has no good move it is probably not hard to solve it but I missed Qxd4+ when I tried to give a fast solution. p22375 w UriBlass 1852 2.7 seconds p22375 w MagicCat 1621 New rating record: 1769 p22375 w MagicCat 1621 2.9 secs and yes it is overrated and sacrifices are easier to see than non sacrifices p22375 w drad 1651 the reason it's high rated is because Qh4 also looks like a kickass move (and is slightly winning). That's where I went wrong p22375 w grom43 1654 But, but, it's mate. Not a mate in four, either. Not even three unless you count interposing uselessly. p22379 w UriBlass 1852 316.0 seconds p22379 w nm32 1653 Very easy. Is this really 1900? p22381 b spacecowboy 1394 This problem has a high rating for a mate-in-one. Don't you think? p22381 b wald 1565 a mate in one! I wonder why this is so hard to see that its rating is >1500 p22381 b Chessdoom 1586 I think its excellentXD p22381 b Leucky 1538 omfg, missed it. p22381 b Leucky 1538 now i got it right in 9 secounds! :-) p22381 b UriBlass 1852 There are mate in 1 with higher rating p22381 b Elroch 1453 Should be easier than it is p22381 b Elroch 1453 But any mating net deserves stars! p22381 b OldPatzer 1054 Checkmate: Ne8 mates trapped K(f6). p22381 b themagician 1543 You've solved problem p22381 in 2.9 seconds. ( Result 1.00 : 0.00 ) Your new rating is 1688.32 (+6.38) p22381 b tdemedts 1728 unbelievable, i missed this! :-s p22381 b joakimvitriol 1661 first checkmates lol p22381 b marcotheknight 1532 tricky p22385 b eragon21 1754 what the heck, this cannot possibly be 1700 p22385 b UriBlass 1852 easy but missed the possibility Nxc3 and failed in this one by playing Qxc3. p22385 b UriBlass 1852 45.2 seconds p22385 b rathkeltair 1694 1735??? p22397 w Elroch 1453 Nice drawing combo. I am bemused by Crafty's assessment - white should clearly move the R back and forth from b1 to d1 which is, of course, equal. p22399 b stoyan 1167 nice trap p22401 w theKnife 1671 Nice. p22401 w pablobento 1546 it's easy ng6+ i'm solved in 5.23 seg p22401 w deusdeusdeus 1459 very cool p22401 w deusdeusdeus 1459 very cool p22402 w Hyperbeam 1761 Now this is tactics...! p22402 w Hyperbeam 1761 nice p22402 w atel2000 1586 Very nice problem p22402 w rathkeltair 1694 nice - should have been obvious but it took me ages! p22402 w JSorel 1664 took me ages too... p22404 w eragon21 1754 easy p22417 b UriBlass 1852 failed. did not try to attack the indirect attacker and played 1.Nf7+ p22425 w Elroch 1453 Surprisingly difficult to find the second move p22425 w grom43 1654 Seems all forced, not a "problem" so much. p22428 b underated 1374 get it right but 14 seconds to think about...come on. I stil lost points p22432 w Elroch 1453 Nice mid-board net p22432 w OldPatzer 1054 Checkmate with B, R, N, and P. p22432 w JacobTomlinson 1263 That's the second sneaky checkmate I've had in a row! p22434 b Boriskudelin 1754 кто-то еще комментирует задачи? p22434 b Boriskudelin 1754 кто-то еще комментирует задачи? p22443 b JoshBrack 1626 8.8. i always liked this problem. :) p22447 w Chessdoom 1586 a realygood 1, played it also in a real match ;-) p22447 w Fromper 1338 I kind of disagree with this one. Why does it matter what move black uses to get out of check? White should notice that he's about to be mated and avoid it, so this isn't a forced sequence. p22447 w wald 1565 I disagree with Fromper. It does matter that the move is forcing. For instance after 1...Kf8 2 e3 White is still alive, but not after 1...Qxc7 2 e3. p22447 w mbingham 1437 It seems wald has missed the point. Fromper was indicating that WHITE didn't have to do dxc7, and that, therefore, it wasn't a forcing sequence. Of course, that doesn't make it a bad tactical exercise by any means. p22447 w wald 1565 rubbish, mbingham! Qxc7 is the ONLY winning move, it therefore is very forcing. Albeit it doesn't force a mate, it forces the win! p22447 w jirka 1360 very nice p22447 w underated 1374 great puzzle and excellent comments from all. p22447 w NK123 1263 i agree with wald p22447 w grom43 1654 wald got it right. The easy way to understand 1...Qxc7 is: you GO UP A PIECE. :-) You're also going to win the d-pawn. I mated my grandfather like this once, the last time he played me in fact. He gave me a book by Capa and that mate was in it. Who could know a chess problem on CTS would bring back 40 year old memories? p22448 w UriBlass 1852 16.0 seconds p22448 w UriBlass 1852 8.3 seconds p22467 w underated 1374 lovely sequence. p22467 w Holy 1098 Very difficult for the rating. p22467 w detroitman 1469 easy p22468 w UriBlass 1852 16.1 seconds not hard fork but hesitated if to play it. earned rating inspite of it. p22468 w UriBlass 1852 19.8 seconds p22468 w UriBlass 1852 6.2 seconds p22473 w Schumi 1523 Wow. How is this rated 1526? Avoiding a mate in one. p22473 w grom43 1654 Wow. p22473 w Leucky 1538 I assume that some people just defend against one of the two checks. p22473 w barz 1708 r1b1k2r/pp3ppp/2p5/q7/1b1pNP2/8/PPPBQ1PP/R3K2R w KQkq - 0 1 p22486 w spacecowboy 1394 I know 1...Qh4 forces mate in three more moves. But what about 1...g2+ 2.Kxg2 Qg5+ 3.Kh1 Nf4 4.Rf2 Bxf2 5.u Qg2#; this forces mate almost as quickly as the solution, 1...Qh4 does. This problem is a dual. I hate duals. Throw this problem out. p22486 w JamesBJames 1657 Not quite, spacecowboy. g2+ is actually good for white! . 1. g2? Kxg2 2. Qg5+ Kh1 3. Nf4 Ne3! and the mating attack is stopped. . If Bxe3 afterwards, white has Rg1! (if bishop takes, rook takes and starts his own mating attack.) p22486 w theKnife 1671 2r2rk1/1pp2pp1/p2B1qn1/3Pp3/P2bP3/1Q3Pp1/1P2B2P/2RN1R1K w - - 0 1 p22487 b floreatdunum 1719 Crap.

Very nice. p22499 w LaskoVortex 1327 Much more difficult than the rating suggests. p22500 w rafael6478 1517 This problem seems to be from a Ruy Lopez Marshall Attack p22500 w polgary 1530 Ehlvest-Geller 1987 , but without 19.Nf2?? p22508 b DocB 1237 your the reason joy sinned/your the reason joy sinned p22508 b DocB 1237 YOU'RE THE REASON JOY SINNED/YOU'RE THE REASON JOY SINNED p22510 b MagicCat 1621 Overrated p22510 b MagicCat 1621 Overrated p22510 b grom43 1654 nice problem, to give the Nf6 deflecting the Rh6 all the time Black has queen en prise). p22510 b JoshBrack 1626 i freaked out and took the queen. fear's a bitch! p22512 b Elroch 1453 Threaten mate, discovered threat on R.

I don't get it. p22537 b mbingham 1437 Another pathetic waste of space. Really, you guys should specify who submits these problems, because *one* of the guys who does is recently post-op lobotomy and should be restricted until after his therapy is completed. p22537 b macLeay 1639 Crazy. This is a losing position, almost resignable p22537 b kendal 1531 What is wrong with you people? This site is free! You can choose to play here or not. Learn a little appreciation. p22537 b polgary 1530 no star - p22537 b QuickFire 1582 Look... I'm also annoyed that I spent too long looking for something which wasn't there before simply playing pawn takes rook. But the fault is in me, not the problem. So 2 stars for ARGHHH! factor. p22541 b underated 1374 excellent sequence. A real surprise. p22541 b suddenlysomeon 1276 A relatively common mate, useful to know. p22548 w UriBlass 1852 problem 23176 to solve 5.9 seconds relatively easy p22548 w UriBlass 1852 8.2 seocnds p22548 w barz 1708 â—„ Position â–º 3k4/3P4/p1pKP3/2P5/3R4/6pp/P3r3/8 w - - 0 1 p22558 b KingKarrl 1163 Should've known those stacked pawns were serving a purpose. p22559 w spinningrooks 1128 A mate that isn't so clear at first. p22568 b ankka 1302 Pretty nice! :-) p22570 b Prufrock 1509 Very good! A lot of good ideas in there p22570 b iwinyoulose 1858 FU Nc7 also wins p22570 b QuickFire 1582 It's an OK problem. Nc7+ isn't the easiest win -- especially compared to the 3.Bxc6+ line. p22570 b QuickFire 1582 With the help of Knight, on the message board, I no longer think that 2.Nc7+ is winning. I played 2.Nc7+ because I didn't see the removal of the guard in the 2.b3 variation. I only thought the position might be winning when I looked at the analysis at the end of the problem, which states: ({10:+1.99} 2. Nc7+ Ke7 3. Nxa8 Bd7 4. Nc7 Rc8 5. Nb5 Qxc4 6. Na3 Qc5 7. O-O $18) Implying that white can save the knight which takes the rook. But I don't see how. After ...Kd8 there is no way back from the corner. I've tried to find the solution with Fritz. 1.Nc7+ Kd8 2.b3 Qb4 3.Nxa8 Qxd2+ 4.Kxd2 e5 (Fritz assessment still +1, white winning) 5.Rad1 Be6 Fritz assessment of the position drops to equal, then a little lower. Computers do that kind of thing, sometimes. p22570 b theKnife 1671 p32538 is exactly the same ! p22570 b kwanpin 1752 very nice puzzle !!!! p22570 b blackk 1535 You can equally win the queen with 2.Bxc6 , this problem has really two solutions. p22570 b tomohawk 1833 Good catch, theKnife. p22578 b ankka 1302 A great endgame problem! p22578 b lancer2000 1410 Not buying the analysis. p22591 b limbo696 1359 While Nxe6 is the best move for white, it is still not winning in this position. Crafty's analysis is off too and would be different if given more time to analyze the position. Fritz 8 rates the position at -2.22 after black moves Bxc5. p22591 b Quietus 1704 This should not be 1500 problem... should be much higher. p22591 b LaskoVortex 1327 White is beat up and has no way to stop the pawn storm AND the heavy artillery on the open c file. Best is to play for a draw, which is what he can do after the N sacrifice. The take is forced as after the exchage with the rook, white gains 3pts in material. Once the white Q and black K are in a duel, white can force the draw, which is what crafty is getting at here. p22591 b levkipos 1386 forcing a draw is also important sometimes p22591 b jsobo 1427 agree this should be higher... or my rating should be lower... I still have a hard time seeing it... even after looking at the solution... p22591 b ajotatxe 1405 What?? This is not tactics, but strategy. p22592 w UriBlass 1852 4.3 seconds p22592 w JSorel 1664 missed p22593 w misterchew 1012 how many people are on here because their dad made them?? p22593 w LowScore 1564 maybe 0.1% (about 30 people) p22594 b antielectron 1223 A nice opening problem p22598 b Holy 1098 Show the next move. p22599 w tjumen 1598 probably wouldn't find this move during a rapid game p22603 b Hyperbeam 1761 Argh...! p22603 b sleiman 1406 I'm hitting myself! p22603 b sejo1 1600 mate in 1 p22613 b wcahleter 1332 I Think solucion is 2.Qh1 too, next mate, and Crafy only show 2.f3 p22622 w UriBlass 1852 problem 23050 to solve 6.4 seconds and still lost rating. took me time to see that Qb4+ threats h4 p22622 w joakimvitriol 1661 fork p22625 b jimmy 1529 i m the best p22625 b dfan 1616 That's not a problem. p22625 b spacecowboy 1394 Judging by the comment that dfan made, he didn't understand something when he made that comment. Those who don't understand should go to the message board and read the posts by JoeLag and SveJoe on August 24, 2005. p22625 b floreatdunum 1719 Rank piss. p22625 b floreatdunum 1719 Again. Why has this ordure not been swept away? p22625 b priamos 1472 Ranking schould be 500! p22625 b priamos 1472 Ranking = Rating! It's not a problem. The high rating makes it to a problem, because you think there must be a deep kombination. p22625 b smotherhubbard 1838 I don't really care what comments JoeLag and SveJoe made, there's no point in having a problem with a response this obvious. p22625 b texas 1392 gxf3 was so obvious I thought it must be Bxf6 and got it wrong. p22625 b soberjudge 1531 1638?? This problem is the equivalent to a speed bump, doing nothing but penalizing quickness p22625 b Svenja 1588 Rubberbullshit and a waste of time p22625 b tomohawk 1833 It penalizes people who have gotten into the very bad habit of playing the first forcing move they see without thinking about it first. Good problem. p22625 b Vandebent 1701 Please get rid of it. p22625 b Svenja 1588 Rubberbullshit p22625 b kendal 1531 Can I point out that the rating is based on people's responses, and that thus people have found this to be relatively difficult? p22625 b rathkeltair 1694 correct but pointless p22625 b Leucky 1538 I love this kind of problem! I also looked at some tactical possibilities with Bxf6 or Nd5, but nothing worked. So the task is to find out that there is no tactic. CTS is not about finding a winning combination everywhere. And the rating is given by all users who try this problem. So i lost some points because i thougt long and helped the problem to hold a high rating. p22625 b LowScore 1564 Hello Leucky! :-) p22625 b JohnSmith 1502 Bullshit. I hate these kind of "problems".

Those who don't understand should go to the message board and read the posts by JoeLag and SveJoe on August 24, 2005. p22771 w edgy 1645 you are a pompous windbag, as well as being wrong. p22771 w floreatdunum 1719 A total piece of crap. Get rid. I spent loads of time looking for the trick. There isn't one, hust the move you first thought off. GET RID. p22771 w tomohawk 1833 Good problem. Sometimes tactical positions do NOT have a solution. One skill is to learn when there is a tactic and when there isn't. p22771 w Elroch 1453 I totally agree with edgy. The only reason this is not very low rated is that people look for a genuine problem that is not there. p22771 w jokim 2000 Good in CTS's setting p22771 w Vandebent 1701 Completely nonsensical.

After 1.Ra6? the 2.Bc1? destroyes whites advantage decisively. p22776 w Garryback 1581 addendum: without any doubt 1...Nc4 was the best p22779 w underated 1374 great little push and pull. p22779 w memo 1570 2. Kxd2 blunder ruins the problem p22779 w MaltaCross 1155 [1] Even if 2.Ke2 (note Crafty's line hereunder) rather than 2.Kxd2, White is a piece ahead anyway. [2] After 2.Kxd2, the remaining White Bishop is pinned (to its King), and so cannot capture the forking Knight after 2.Nc4+! p22779 w MaltaCross 1155 or rather, after 2...Nc4+! p22782 b phmilet 1553 4.8 secs! The move 2. Rxb3! is principled: Two pawns on the sixth should win against a lone rook. 4. e7! is a last finesse: Black must be forced to move the rook, not the king (4. d7? Kc7). Great problem! p22785 b pdubs 1146 so simple, but I missed it... p22787 w television 1655 but h5! must be in the problem. p22793 b UriBlass 1852 25.8 seconds hesitated too much because searched for mate or something better p22793 b tjumen 1598 DEFENSE p22797 b notyetagm 1467 An opening trap from the Torre Attack. 2 Qh4! is a DOUBLE ATTACK against the LOOSE Black e7-bishop and the LOOSE h7-mating focal point, threatening both 3 Qxh7# and 3 Bg5xBe7 followed by 4 Be7xRf8 . p22797 b theKnife 1671 See http://www.youtube.com/watch?v=UAXpqvYjDOI p22797 b UriBlass 1852 1.9 seconds p22797 b grom43 1654 That's just excellent. p22798 w smotherhubbard 1838 winning queen with qxb5 is good enough p22798 w mykingislonely 1861 I agree. p22799 w UriBlass 1852 tempted by Qh3 that played too fast and of course Rxh2+ mate in 2 is better missed the fact that c6 threat the rook and thought white has no defence p22799 w UriBlass 1852 again Qh3(one more second and could see the mate in 2) p22805 w UriBlass 1852 45.1 seconds p22805 w television 1655 11,2. p22806 w UriBlass 1852 problem 23499 to solve 2.5 seconds easy. trade queens to capture the bishop later p22806 w UriBlass 1852 2.6 seconds p22806 w joakimvitriol 1661 anihilating pinner p22808 b MaltaCross 1155 The rook is doomed!

The discovered threat is surely too obvious for anything about 1400? p22815 b notquitekarpov 1381 Agreed. The pin is a pretty obvious motif, at least for this rating. p22815 b benu 1193 While the pin is an obvious MOTIF, with the sequence of moves leading to a pin on the QUEEN (as opposed to the king), it may not be as obvious at the 1400 level. p22815 b joakimvitriol 1661 pin p22827 w floreatdunum 1719 solution needs more moves p22827 w UriBlass 1852 problem 23352 to solve 4.6 seconds trade and after it double threat of rook and fork against the queen. p22827 w UriBlass 1852 4.4 seconds this time p22827 w UriBlass 1852 1.0 seconds p22827 w tjumen 1598 not easy. agree, it needs more moves p22830 b Herman 1765 Qxc4 is winning as well p22830 b armeno 1859 I guess Mate in 3 is a little bit beter;) p22830 b UriBlass 1852 also failed for Qxc4+ that wins a rook forgot to look at the problem rating. p22830 b UriBlass 1852 again failed too fast should look at the rating of the problem first. p22830 b LowestRd 1946 I just don't like problems with more than one solution p22831 b Holy 1098 Sure, it seems that you're just taking a hanging piece. But, you have to be sure that the queen won't get trapped. And, there are other lines on the board that might distract the player into looking for other tactics. p22831 b mathaias 1434 I agree, this is is a little more than simply grabbing a loose Rook. p22835 b barz 1708 2r4k/6p1/4P2p/3Q4/1P1P3P/4qpP1/4bN2/1R4K1 b - - 0 1 p22838 w joakimvitriol 1661 pin & attacking defender p22840 w UriBlass 1852 1.0 seconds p22851 w notyetagm 1467 White thinks that he wins the exchange with 1 BxR? pxB.

Check Crafty below after 2 Bd6 Ra8 3 Bf1 Ra4.

First White plays Qe4xNd5?, trying to exploit the DISCOVERED PIN down the e-file. That is, without the White queen on e4 BLOCKING the White e1-rook, the Black e6-pawn would be PINNED to the Black e8-rook/mating square. So 1 Qe4xNd5? attempts to exploit this DISCOVERED PIN. But there is a slight problem. The White e1-rook is now a PINNING DEFENDER of the White d5-queen and is the -only- White piece preventing ... e6xQd5. This OBLIGATION RESTRICTS the MOBILITY of the White e1-rook to the e-file. Hence the White e1-rook cannot also DEFEND the White a1-rook and 1 ... Qc3xRa1! exploits the OVERWORKED nature of the White e1-rook. After 2 Re1xQa1 the White e1-rook would no longer be maintaining its PIN along the e-file, allowing 2 ... e6xQd5, and Black is an exchange ahead. MAINTAINING A PIN IS A FULL-TIME JOB: YOU (White e1-rook) CANNOT MAINTAIN A PIN (along e-file) AND DEFEND A SQUARE (White a1-rook) AT THE SAME TIME. p23178 w floreatdunum 1719 It's not that special notyetagam/notquiteapatzer! But your analysis is sound, if a trifle breathless... p23184 w UriBlass 1852 14.0 seconds not easy espacially when white has a check against Qh6 deserves higher rating. p23184 w tomohawk 1833 Since. 1...Kg7 is winning as well, this isn't a good problem, imo. p23187 b Quietus 1704 For the life of God I fail to see why Qe8+ followed by Rxd5 is not equivalent? p23187 b Raeburn 1704 Hi Quietus, Qe8+ Qf8 Qxf8 Kxf8 Rxd5 Rxd5 and now Be6 is not check so it doesn't work.

After looking at it a second time I realized none of the options worked so i should look at what I was avoiding, forcing moves with the queen! I instantly found it then. This so reminds me to examine forcing moves, real beauty. p23351 w mworld 1454 such a pretty queen sac. p23354 b hypersoninc12 1381 WHAT?? what if black playes rxh5 after Qxh5, how can that be the solution, the position is lost p23354 b Socrate 1410 Rxh5 is an illegal move. p23354 b MagicCat 1621 LOL p23356 b UriBlass 1852 I solved it correctly but 3.Ng3+ also wins after 4.Ne2+ and 5.Kf2 so it is not a good problem p23356 b drad 1651 love it :) p23356 b rockym 1626 I just saw the draw, not the win ! p23356 b mykingislonely 1861 Agree with UriBlass. If you repeat the position, it is still the same winning position. (In fact you should get more points by using less time per move) p23356 b grom43 1654 Disagree with Uri that a problem is bad because you can repeat two moves before finishing it. Seems silly to say, pardon me. p23356 b JoshBrack 1626 you're never going to get to see a problem like this on the cts unless you can repeat the position. i think there are many more that allow repeating positions too. p23360 w DocB 1237 mudder game, has anyone heard of the mudder game where a tactic never seen before, a corkscrew that led to a windmill p23361 b Pinsu 1601 2.Bxe6 also wins p23362 w UriBlass 1852 problem 23445 to solve failure too fast played h5 and missed the fact that white has Qc7+ p23362 w UriBlass 1852 2.4 seconds p23364 w barz 1708 â—„ Position â–º r3kb1r/1p1b1pp1/p1np1n1p/5N2/4PpP1/P1N4P/1qPK1B2/R2Q1B1R w kq - 0 1 p23367 w Subrosian 1658 Seems...overrated... p23367 w UriBlass 1852 overrated? not to me I blundered by 2...Ke7 not seeing that after Qh7+ Kd8 white wins p23367 w UriBlass 1852 17.9 seconds this time still lost rating points p23367 w ChessPlayer56 1801 No not overrated. But I played 1...Rxc6 illegal move !! p23378 w UriBlass 1852 4.0 seconds p23378 w UriBlass 1852 blundered by Bf8 missing the simple Qxh6+ p23378 w UriBlass 1852 now blundered again saw Qxh6 mate but saw all checks except Qxg3+ and guessed a wrong check after seeing nothing. p23384 w UriBlass 1852 9.3 seconds p23386 b jokim 2000 On the left side is Qb3 such a tempting try, while your eyes should be aimed at the right side of the board. p23386 b UriBlass 1852 played Qb3 and missed Qb6+ when Be3 is not possible p23396 b MaltaCross 1155 [1] Black chose 1...Be6 to ward off the rook's check. [2] After 2.Rxe6 fxe6 3.Qxg7, the White Queen is making TWO SIMULTANEOUS THREATS: (a) the capture of the h8 rook, and (b) mate in 1 with 4.Qe7++. Thus Black must sacrifice his rook to avoid checkmate. [3] Rather than 2...fxe6, Black may opt for 2...Kf8 instead. This saves his rook, but remember that White has just captured the Black bishop for free. p23399 w Dougy 1654 The problem with 1...Nxe4 first is that White can reply with 2.Rxe4! removing the tactic. With the line 1...Bxf3, the in-between move Nxf6+ does nothing to prevent White's problems. p23399 w jokim 2000 Good CTS problem p23399 w rathkeltair 1694 accurate calculation needed to find best move order p23409 b sejo1 1600 vaag p23435 b notyetagm 1467 Loose pieces are the basis of combinations -- Reinfeld/Chernev Here the UNDEFENDED Black h6-queen lined up with the White d2-queen along the c1-h6 diagonal is the tactical factor which makes this combination possible. p23435 b mjb1974 1468 easy to spot if you are looking to sac for the win p23435 b JoshBrack 1626 i think maybe it's cause the rd's so low on this one that it's rated so low. if everyone only got this once every 10,000 tries i don't think many folks would get it. p23439 b zant 1768 2.Nd5 also wins p23439 b tomohawk 1833 zant, couldn't Black play ...Qc6+ there? p23439 b UriBlass 1852 played 3.f5 and missed 3...Qg5 p23443 b UriBlass 1852 3.2 seconds p23443 b rathkeltair 1694 needs more moves p23450 b staham 1366 If the king takes, Qh1+ mates next move. If the bishop takes, Qh1 followed by Qh7+ and Qh8 mate. p23450 b joakimvitriol 1661 NQ in action p23453 w UriBlass 1852 blundered by RxR+ thinking wrongly I have later mate p23454 b ajotatxe 1405 I'd include some more movements p23454 b MaltaCross 1155 A check forces the Black king from the edge of the board and into a pin, that costs him his remaining Queen. p23463 b OldPatzer 1054 Q fork: 2.Qd3+ forks K(h7) and R(c4). p23463 b MaltaCross 1155 Note that the e3 knight is "pinned", since it has to guard the mating square g2! Therefore 2.Nxc4 can result in 2...Qg2++ (mate). p23473 b sleiman 1406 be careful! p23477 w spacecowboy 1394 I hate this problem because it is a dual and it should be removed from the server. There are at least three solutions that I can see. Either 1...Ng3+ or 1...Nxf3 or 1...Bxh6. The next time somebody says CTS is so good, remember that duals are one of the faults. p23477 w JoshBrack 1626 Bxh6 also looks interesting to me. possible better. i'm no grand master but this could be a dual solution, possibly the text inferior? maybe? p23477 w underated 1374 I'd prefer a queen trap with Bxh6 also...dont remove from server, good point of discussion! p23479 b UriBlass 1852 8.2 seconds p23479 b joakimvitriol 1661 RR & minor piece for Q & minor piece p23481 b SourKraut 1260 why not d8Q+?? The Queen can be taken anyway in the next move and we have another Queen p23481 b LowScore 1564 after 3.d8Q+ there is 3...Bxd8 and White loses. p23481 b Igor07 1381 nicht komplizirt, aber abgenehm p23484 b UriBlass 1852 6.6 seconds p23496 b slacker00 1521 2 legal moves. One of them allows mate in 2. Tough choice. p23496 b LowScore 1564 3 legal moves...one which wins, one which allows mate in 2, and one which looks like a cool queen sac but loses. Of course, if you're too weak to see the queen sac, it's an easy problem. :P p23496 b barz 1708 â—„ Position â–º 5k1r/p3pp2/6pp/8/QP5P/2q3P1/4KPB1/2rR3R b - - 0 1 p23497 b sarciness 1465 Plyed Be4, missed it! p23512 w ngnblcn 1851 nice p23513 w stevelco 1412 This one is relatively subtle.

I found it fast because I didn't look at the high rating ! And ClownPrince, What do you mean by irrelevant comments? Arthurrocks was asking a question and UriBlass was giving the time which is fine also. I think you are like Garryback. p23525 b Jonathanzzz 1910 Just out of curiousity, why do people give the time they solved it in? I see many people doing it. p23525 b UriBlass 1852 The reason is that I want to compare with future time to see if I improve my memory for problema but I stopped doing it after people complained. p23537 b UriBlass 1852 7.8 seconds too short should include Qxd5 Bxh7+ p23546 b smotherhubbard 1838 ???? Simple recapture p23546 b tomohawk 1833 And yet many will try moves like Qxh6 or Rxg7+ because those are the sorts of moves that are often solutions here. Problems like this keep the guessers honest, in my opinion. p23546 b JSorel 1664 I agree with tomohawk, as usual p23549 b UriBlass 1852 2.4 seconds p23551 w UriBlass 1852 problem 23224 to solve 7.3 seconds Nxe2 with the idea to capture the knight does not work because of Rxe4 so first we need to escape with the bishop with a threat. p23551 w UriBlass 1852 14.8 seconds p23552 b beydagh 2020 Strong move! p23552 b JeremyW 1597 so the idea is to counter attack-- on Bc6 f3 Qg3, w/ the devastating Qxe6+ forcing the Q away and grabbing the Bh2.

It's only high-rated because people can't believe it's so dumb. p23811 b spacecowboy 1394 Yep, this is 'one of those problems'. What edgy is basically saying is this is one of those ordinary positions that catches people looking for a sensational lightning bolt they expect to come down from the sky. In my own experience, by the time I realized the lightning bolt was never going to come, I had exceeded the time limit. But I still think the problem deserves its high rating. Problems like this 'keep us honest'. p23811 b Quietus 1704 Problems like this gets on my nerves If that is the case the 1.Rc8 was also ok. p23811 b tomohawk 1833 I agree with spacecowboy. One of the things that people have to learn is how to determine when there is NOTHING available. Many promising looking positions have no combination. So there should be a few promising-looking positions tossed in to foul up players who randomly choose the first forcing move they see. Not every position should have a forcing solution. p23811 b tjumen 1598 QC7 is the best move much better than alternatives. I was also looking for some unexpected move though. p23811 b grom43 1654 I finally chose 2 Qc7 expecting to be wrong because there is nothing else there.
