But the question is, what do you want to know from the null-move search. For a fail high, all you can discover is "if I do nothing, the score comes back >= beta" which is enough to convince me that I can simply return beta here, as playing _any_ move should raise the score even higher (non-zug of course). Does it matter _how_ good the score is? Or just that it is >= beta?
