Hi, I would like to know how do you detect if a move is a mate_killer and/or an historic_mate_killer. In your page on chess programming you say that if a killer_move has a mate score the it is promoted to a mate_killer_move. But I guess a mate score can be a winning score or a loosing score. With this in mind I don't think the following code would do it: if (abs(score)>MATE-200) then this is a mate_killer move. This code would detect both positive and negative mate scores, so it wouldn't work (I think). So how do you do it? How do I know if a mate score is a winning score or loosing one? Best regards, Alvaro Cardoso
