Do any other of you guys or commecial >programmers not use null move? I know that Rebel does not use null move(the reason for not using null move is that Rebel is using other prunning ideas and using also null moves will be too much). I read that chessmaster6000 uses null move but I think that it does not use it in the same way that other programs use it and depth 3/12 probably means that it does not use null move in the first 3 plies.
