I do not agree with this comments. The pawn sac for activity
seems not so bad. Look at the [typical computer] gsme. Between
moves 24-37 Crafty made no progress at all to strengthen its
position. And with 38.Bd3?! the program allowed Shredder 9 the
interesting but not fully justified knight sac on f2. But why
did Crafty the horrible move 32.Ke3?? Anyway, Shredder did not
win the game because it played superb but because Crafty played
a very poor game I think.
