When you call Evaluate() it looks in this hash table to see if it has previously evaluated this position, and if so, it just returns the value. Otherwise it does it's normal evaluation, saves it in the evaluation hash table, and then returns the value. Depending on your evaluation function, this may or may not provide a speedup. Cheers, Tim.
