This works find for positions with 1 >zugzwang, but in this position black gets hit with about 10 of them :) Double null move correctly implemented should not have any problem in principle, with as many Zugzwangs as you want. Of course, the Zugwangs will "eat" a lot of depth, and search time/depth might not be enough practically soon. Theoretically (with infinite) time, it should be able to solve any problem. Normal null move pruning won't, of course. Regards, Dieter
