Currently, I use these pawn 1000 knight 3000 bishop 3000 rook 5000 queen 11000 king 12000 (but can be zero without affecting program) Mobility generally values bishops and knights appropriately based on the demands of the position (square control bonus.) I keep two rooks lower than a queen since the program got into trouble trading defending against a marauding enemy queen. Also, two minors are generally worth more than a rook and pawn also based on the demands of the position (also square control bonus.) I don't change piece values during the game (and wouldn't!) --Stuart
