2007-08-11 15:58:26tomohawk1818Should include ...Nf8 Qxc2 and Rxa8 
2008-06-16 03:20:10notyetagm1467@tomahawk: Agreed. This problem is the PINNING VERSION of the FORK-OVERLOAD TRICK. 
2008-10-17 00:35:49UriBlass2010Nf8 Qxc2 and Rxa8 costed me some time so I earned less rating points then people who did not calculate this line.

2009-02-04 11:40:32UriBlass2010blundered by Qxc2 that I had from memory after seeing no logical alternative but did not remembner that I need to play Re8+ first. 
2010-11-11 15:16:00Garryback1679standard - but tomo is right (as always)

2011-10-13 20:08:11chessisajedrez1758I respect the statistical model used for rating these problems, but this one baffles me because its type belongs in the 1300-range problems. Actually, the 1600 rating may confuse someone into believing the solution is more complex and spend more time on it. I did it in 3.8 by guts instinct. See (UriBlass) comments. A very good player and much better than me ... (UriBlass) 3.8 secs! :-} 
2014-11-15 03:43:50floreatdunum1729Agree with tomohawk
