2006-06-09 09:02:26Markusgoth2122Incredibly great! 
2006-08-28 17:42:14vhgilesf1332vaya, excelente problema. 
2007-09-10 11:28:27Markusgoth2122In fact this is a very deep problem that worth playing. 
2007-09-10 11:29:53Markusgoth2122The 3rd move is so tactful that it ensures the victory. Nice problem indeed. 
2008-07-31 00:40:51Blackstorm1264the 3rd move require some hard thinking, while the 1st is quite easy, althought not simple to see. 
2009-12-26 22:38:42mykingislonely1781Takes a lot of time to see how many of the moves don't work. Quite a nice trick by black. 
2010-02-17 10:13:46Garryback1679very instructive is also to play the best black 1...move 
2010-04-14 18:59:28Piter2271620It's incridible :) 
2010-11-11 15:41:13Garryback1679only can repeat : one of the best black could also play the trap 3...c2!
