Without an extra ply or full iteration you can't be certain >that the new move really is better. You cannot be certain with a full iteration that the new move is better but in most of the cases it is better. It is possible that a program chooses a worse move after another iteration because it "believes" that the move is better but the move is worse. In some cases the new move might be a lot >worse than the old one and I don't think it's unusual. If we agree to define a better move as a move with a better evaluation then the new move is always better than the old move and it is not important if the program did a full iteration. Uri
