Any other white move draws. Unfortunately, the opposition doesn't help you a bit if your opponent can "pass" (which is what the null-move allows). IE I play Kd5, which wins, but you pass, and now _you_ have the opposition and the game is a draw. Black is in zugzwang because as it sits after white plays Kd5, the game is a draw, but as soon as black moves its king, no matter where it moves to, the game is lost. But null-move allows it to not move and hold the draw, greatly confusing the search...
