Undoubtedly, it shows us in good part how strong is at the moment a chess program in the some end games. Topalov that fights hopelessly until the end in search for a draw, carries out the movement of the black pawn to f2 and arrives to this interesting position after 56 movements : [D]8/8/8/1k6/4p1B1/8/P2K1p2/8 w [D] - - 0 56 wKd2,Bg4,Pa2/bKb5,Pe4,f2 (White Move) In this position, there are only two moves that give to white a won game. And the Great Master Anand, executes the winning movement without hesitations, playing the only one that gives to the target a winning game. He plays Be2!! (the other one that wins is Bh3!) But here there is a problem with many chess programs and I am really surprised. Almost all the strong chess programs, (Shredder9, Fritz, Junior, Chess Tiger etc, etc) think mistakenly that the best play is King e2?? Shredder 9 or Junior 9 that are able to arrive and to surpass the 30 plies of depth are not available to understand that with the move of the white King to e2, the game is completely draw. It is truly incredible Crafty and Ruffian 2.1.0 can see the wining move quickly, just in a few seconds of “Thinking”. Crafty and Ruffian can see, that after the bad King e2, black have : e3, and if Ad7+ King b4 a4, and the black king stays in the square a5 and b4 until the eternity. The white king cannot kill the pawn on e3 because black win inmediatly with the simple f1=Queen. Why the strongest programs in day cannot see that? After 56.Be2+ Kb4, 57.Kc2! Ka3 and 58. Kb1, black pieces don't have any hope and Topalov have resigned. A nice endgame, but at the same time, a hard test for some strong chess programs. Best Regards! Tanya Deborah.
