2005-10-02 06:18:45edgy1632Ne5 is just as good. Bad problem, remove it. 
2005-11-07 19:19:03edgy1632ne5 is STILL also crushing; this is a very bad problem 
2005-12-11 04:40:21lummox1662as others note, ne5 also wins 
2005-12-12 22:41:26edgy1632Once again, this prblem has been utterly broken for months. Remove. 
2006-05-30 10:02:12Markusgoth2122... but the point is, nb8 also wins. 
2006-09-24 00:27:18edgy1632No, the POINT is that Nb8 is not th eONLY winning move, so this is a BAD PROBLEM. 
2007-10-04 16:04:32rollingstone1852Very bad problem!! I completely agree!!Ne5 
2008-02-23 03:44:49eragon211830Terrible. A winning variation cannot be better than another winning variation. 
2008-05-28 03:52:30tomohawk1818Agreed with the posters above. 1.Ne5 is winning; that 1.Nb8 is a better move is not really relevant as playing moves that crafty finds +4 is going to be enough to win the vast majority of times. ;-) 
2008-09-25 19:04:26kwanpin1752i played Ne5.. and wrong??? 
2008-10-16 22:00:17jokim2000The difference between 1. Ne5 and 1. Nb8 is winning a Rook for a Knight and winning a full Rook for nothing. 
2008-10-16 22:00:31jokim2000Forgot to add the stars. Important problem! 
2008-12-06 11:31:37kwanpin1752Nb8! 
2009-12-30 16:37:53mykingislonely1781More than one solution. 
2010-08-07 09:29:03UriBlass2002easy to see that both Mb8 and Ne5 win material and in this case the solver need to calculate the better move. 
2012-04-17 16:02:08Garryback1679dual 
2017-10-11 21:38:19Bisonratte1501concerning the rules of the site its no dual. jokim is right.
