2006-01-31 01:05:31jmw1281571What's wrong with this line? 2. Qxc8 Qxc8 3. Ne7+ Kg7 4. Nxc8 Rxc8. 5. Rac1(pinning Bishop to rook) Bd3 6.Rxc8 Bxf1. Kxg1 
2006-06-14 02:35:02Drahacik1439Qxc8 is just as good, and should not be counted as a failure. This problem is flawed. 
2007-01-04 10:29:59dond00101572I had the same thought. Qxc8 is just as good. 
2007-08-21 16:37:37nune1570Qxc8 is not nearly as good. In the main line white will pick up the e and f pawns too. If "2. Qxc8 Qxc8 3. Ne7+ Kg7 4. Nxc8 Rxc8. 5. Rac1" the bishop can escape to f5 where it protects the rook and escapes the pin. 
2007-10-26 08:56:35LaskoVortex1359This problem should be rated much higher. 
2007-12-17 00:32:59Marvol1466Qxc8 is only better after 8 ply or so; this problem should be rated higher than 1500. 
2010-01-07 17:00:17Pinsu17802.Qxc8 it's a correct move. 
2010-03-14 14:36:21bingobilly1540Problem should be rated higher or played out more moves. 
2010-07-10 02:23:40john2001plus1615Ne7+ is better because white picks up two pawns afterwards, but this is a subtlety that is really hard to spot. So it is either a great problem or bad problem depending upon your perspective. I am not sure that I could ever get that in a few seconds. 
2011-11-05 08:51:40Garryback1679r2q1rk1/7p/p7/1pQNp3/5p1P/8/PPb3P1/R4RK1 b - - 0 1 
2012-01-27 22:42:19chessisajedrez17582.Qxc8 Qxc8 3.Ne7+ Kf7 4.Nxc8 Rxc8 5.Rac1 pinning lead to a R vs B ending. Like Fischer said, simplify to a technical win everytime. IMO - No need for leaving the Queens on the board. Can't argue with Crafty, but 4. Qxe5 is complicated (I will always take with the Queen anyway). 
2013-10-31 17:24:44grom431861@chessisajedrez: but it seems far from a technical win (count pawns). After 4.Qxe5 it seems to me White has a great attack (and the pawns j01+). 
2013-12-17 21:03:08ididntdoit1725QxR wins easily too and is simpler. 
2014-02-07 05:57:40axc11507I went with QxR also. It's easier to spot for me. 
2014-03-23 10:29:55Bisonratte1501unfair problem imo. i like @chessisajedrez practical explanations very much, but i understand @groms objections as well. i think, the sideline is worth to study deeply, cause it teaches very much about rook vs bishop endgames. 
2017-03-14 19:21:43chessisajedrez1758In the B v R endgame. It's not the number of pawns but the quality of the pieces. His pawns are up for grabbing; 2 weakness endgame principle) and I have pawns in both ends. I have an uncontested active R. 
2017-03-14 19:23:37chessisajedrez1758The presence of at least two of my pawns erases his drawing chances. All I have to do is place two pawns in black squares. One will Q for sure.
