But i am not looking for good positions for me.. ( i think this is the way normal nullmove works, i pass and then if my oppenent even playing two times in a row can't hurt me then my position is really good) but the opposite, my oppenent is the one who pass, he let me play tow times in a row, so if a can't hurt him, his position is really good.. in that sense i need to see it like: if score <= alpha ? right?... (not if score >= beta because my oppenent is playing nullmoves not me)..
