Hello! True or not true? More your chess game become knowledgeable about how to play the game, more it become unefficent. And this is not only because it start to be more complicated, not even because of the lowest ply - not at all! Reason is that now your game unstead of 30 nodes need to see only 3 or 7. And more you have the moves (in the sense of nodes) to see (in the same ply) more efficently it can be done. Usually, (in my game) before generating moves (nodes)for a given position all the data about two Kings is found. Data about one King is found for knowing the legality of each move. Data about opposit King is found in order of knowing what move will end by checking the adversary King. For more moves you use the same data, more efficently it is done. Leonid.
