If it has a zugzwang, you will _never_ see it if you don't check for it
(verification search, double nullmove), or use another trick like force
nullmoves away from the root (that is what Crafty does).

You can always play the 'nullmove' no matter what depth, so you'll
never realize the nullmove is no good.

i.e. you make an illegal move that is not possible in the real game, and
increasing search depth won't change this.
