It's worth a try but moving stuff out of the leaf eval into to the move routine can often be a loser, overall. You have to undo the computation as you back up the tree. And you are paying a cost for info you may not need : e.g. if you can cut off using material scoring only, then all your incremental positional eval is wasted. It's still maybe worth a try but I wouldn't be surprised if it didn't help. --Jon
