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.
