Subject: Null move idea

I see a way to remove a lot of null move zugzwang problems w/o verification
search.

If a move was searched previously and result was null move cut-off with
eval>=some_value, but when the position was reached by second time with
beta>some_value it caused fail low (eval<some_value) then it's possibly a
zugswang node and we must store thia info in TT. When reaching this position
again we must disable null move.

I'm experimenting with this idea and need your results to compare.
