I would not believe, that most chess >programs update the killer move, when a best move is found. At least not in >general, when the best move is a fail low move (and this will happen very >often). perhaps I do not understand something but my chess program has no best move in case of fail low because it does not claulcate exact score for moves that fail low. Many chess programs won't store a move in hashtables, when the best move >failed low (UPPER_BOUND), either. I am not going to store a move when I have no idea about the best move. Uri
