Subject: nullmoving - an idea...

I don't know if this has been done, probobly has, but here goes anyway. Lets say
the computer gets to this position somewhere in it's search.

[D]2k2q2/pp4pp/2p5/2p1p3/5n2/1NP4P/PP3PP1/2Q3K1 w - -

white to move is ok, but when the search nullmoves, black wins with Ne2+!!. Ok,
my idea (and probobly loads of other peoples), is to store this move, Ne2+,
since for alot of whites possible moves, Ne2+ still wins the queen. I'm not
quite sure how the code would work, or how effective this would be. Maybe you
wouldn't want to store it if it were a capture? as they are checked early
anyway. You could possibly store it as a killer move? I don't know. If it has
already been done, can people tell me how effective it is? if at all.

I have heard of mate threat extensions...does that use null move to?
