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*.
