The following position is from a game between Rebel 9.0 28 MB HT and Fritz 5.03 64MB HT on a PC with a AMD K6-200. WKh3, Rh6, Pg3,g2 BKc5, Rb6, Ph7 White to move Rebel 9.0 as white was unable to find the winning exchange Rxb6 in 5 minutes. He played Rxh7 and after some moves the game became a draw. I have tested the same position with Shredder 2.0 64MB and Genius 5.0 32 MB. Both programs didn´t see the winning exchange in 10 minutes and played the same move as Rebel (Rxh7). I´m not sure if the game could be a win for white after Rxh7, but after Rxb6 the win should be clear. Does any chessprogram play the move Rxb6 and see the win ? The evaluation should be at least 4 pawn, if the program has understood the position. Why is this position so difficult for programs ? Best regards Kai EMail : kai.skibbe@provi.de
