However unlikely this may be, I imagine it would be terribly embarresing if Crafty missed mate in one in some big important computer chess tournament (if there is such a thing). This is a begginers idea, but perhaps it has some merit (if only to make fun of): I can understand that Crafty would want to avoid positions like these, so you put something in the eval to make it realize these are drawn and to avoid positions like these if possible when searching for a move, but once a postion like this has been reached, would it be possible to have it search for mate before declaring a draw? Crafty would still avoid positions where there is a likely draw, but if for some reason it is unavoidable and the position like this is reached, it would play them properly. Just a fishes idea, Jeff Jeff
