2007-05-03 18:27:07Quietus1704Line should continue 
2007-09-14 20:05:30tomohawk1818Agreed with Quietus. Otherwise it is just guessing. 
2008-12-06 00:55:44Elroch1466Nice move, but... 
2008-12-13 19:20:21milos621916I guess the line does not continue since both 3.Bg6+ and 3.Rf1+ lead to mate. 
2010-02-16 03:55:49grom431821Intuition says it must be mate. Finding that before you sac the rook? Pretty tough.  
2010-07-15 11:03:32barz1628◄ Position ► 1n1r1k2/1rq1ppbQ/2n5/2B5/p3B1P1/1N6/PP5P /1KR2R2 b - - 0 1 
2010-09-24 20:26:2210101631After 3.Rf1+ Qf4 white has no immediate forced mate. 
2010-10-03 08:33:24joakimvitriol1724It is crazy how many mates are there: 1... axb3 2. Rxf7+ Kxf7 3. Bg6+ Ke6 (3... Kf8 4. Rf1+ Qf4 5. Rxf4+ Bf6 6. Rxf6# (6. Qh8#) (6. Qf7#)) 4. Bf5+ Ke5 (4... Kd5 5. Be6+ (5. Be4+ Ke6 (5... Ke5 6. Qf5#) 6. Qf5#) 5... Kxe6 (5... Ke5 6. Qf5#) 6. Qf5#) (4... Kf6 5. Qg6+ Ke5 6. Qe6+ Kf4 7. Qe3#) (4... Kf7 5. Be6+ Kf6 (5... Kf8 6. Qg8#) (5... Kxe6 6. Qf5#) (5... Ke8 6. Qg6+ (6. Qh5+ Kf8 7. Qf7#) (6. Qg8+ Bf8 7. Qf7# (7. Qg6#)) 6... Kf8 7. Qf7#) 6. Qf5#) 5. Qxg7+ Kd5 (5... Kf4 6. Rf1#) 6. Qf7+ Ke5 (6... e6 7. Qxe6#) 7. Qe6+ Kf4 8. Qe3# 1-0

2011-05-20 00:44:47edgy1632cannot be a one-mover. must not reward pure guesswork. 
2011-07-19 08:41:33Garryback1679Line must continue 
2011-12-07 19:28:57SirRick1703also did sac by intuition... would have continued with Bg6+ not being sure how would it end. joakim has done an awesome work! 
2017-08-11 22:27:34grom431821Only line I calculated today: 1...axb3 2.Rxf7+ Ke8 3.Qg8+ Kd7 4.Bf5#. Also, when I looked at position several times I see Black has a decent attack and there is not much time for White.
