I think this is not the point of null move. Null move is "if pass is good enough to an alpha cut, then will be a _better_ move". It is not important if pass is the worse move, is important that there is a better (>=) move than pass (not zugzwang). Then you bet searching not so deep. But null nove is not a trick in Go, because pass is always a legal move. There isn't zugzwang in Go. Andrés Sorry my bad english
