Another attempt at evaluation shortcut In this case we try a rather drastic approach: we simply don't futility prune in qsearch when arriving from a null move. So we save evaluating and also save to mess with eval margins at all because margin is used only in futility. Also accuracy should not be affected, actually it improves because we don't prune anything anymore. bench: 5404066
