Move ordering improved to speed me up 10%. Washed out to no advantage, _until_ I added the stuff about tossing out captures that can't bring the score back to within the alpha/beta window. That made me about 2x faster overall, which is a _big_ gain. Stuart isn't getting all the advantages of SEE yet, and, in fact, It isn't necessary to use SEE on _every_ capture. IE for PxQ there is no need to see if that is +9 or +8. Either is good enough and there MVV/LVA is faster.
