You do not need to exclude the first move from futility pruning, that might kill some speed too. If there are no captures or checks you should just be able to quit - return the evaluation score so it's treated as a bound and make sure there is code to make sure you don't return a stalemate (because there were no "legal" moves.)

Thanks Don this is interesting I will try this.
