Still by the virtue of the fact that you use Internal Iterative Deepening is it not the case that you virtually force a hash hit - ie when you do not find a hash move Crafty searches Depth-2 after which, assuming that it finds a move score of > Alpha, it will store the position in the hash table and this will be used as the effective hash move. Hence for most positions there will be a hash hit. Am I still wide of the mark? You help is appreciated! Steve Maughan
