Tweak statScore condition The first change (ss->statScore >= 0) does nothing. The second change ((ss-1)->statScore >= 0 ) has a massive change. (ss-1)->statScore is not set until (ss-1) begins to apply LMR to moves. So we now increase the reduction for bad quiets when our opponent is running through the first captures and the hash move.
