It's not a research project, it's a chess variant. White gets a pawn on e2, a pawn on d2, and a king on e1. Black gets the full army. White gets to make two moves in a row each time, and the white king may move into check with the first move, but must leave check with the second move. I can usually beat someone with white a few times before they figure it out. It's pretty hard to mate white, it takes a lot of heavy material. But this doesn't have anything to do with null-move forward pruning. All that does is allow the program to say, "Am I still winning even if I pass my move?" If the answer to that question is "yes", then there is probably no reason to make a move, since the resulting position is almost always even *better*. bruce
