I wonder how much benefit there would be to doing a dynamic exchange evaluation on certain moves and just eliminating them from the search. Remove moves that seem to obviously lose material. We might allow sacrifices at the base of the tree and sacrifices that give check at any point. The benefit is that it would cut down on the size of the tree, and perhaps by a great deal. The cost is that the program would be blind to many tactical shots. It would probably miss that a piece is pinned and cannot recapture. If we could somehow keep track of pinned pieces then our dynamic exchange evaluator could be programmed to not eliminate moves when pinned pieces are involved. John
