Shredder blundered Here is example for one of shredder's mistakes but it was probably too late to win the game at that point. It seems that fruit has evaluation of open files when shredder does not have it.

Another test position when Fruit also fails is the following position [D]2r4r/4kp1p/3bp3/1p1p2p1/p1pP1P2/P1P1P1P1/RP1B3P/R5K1 b - - 0 1 I think that g4 is a blunder. Uri
