But isn't the "real" savings in not having to completely do the long search
again? If you do one move generation to ensure the position is the one you're
looking for, you're still saving many hundreds of thousands of move generations
and make/unmake's and evaluations. In the case that the pseudo-legal moves
aren't the same, you just saved yourself from a potentially incorrect score
being returned or incorrect move being played.

Maybe I'll play with the idea and see how much it slows things down.
