I will look at the code later, but for now: You have to allow stand-pat at any point where it makes sense. Chess is not checkers. BxR NxB QxN NxQ is +2, because the third capture won't be made in reality. You'd call QxP PxQ a loser, but you might play the PxP PxP part of PxP PxP QxP PxQ, so if you are trying to identify swapping captures, you have to deal with that case, too. bruce
