Are you saying that there are no positions where the best move is only a draw? I know you know better. For instance there are positions where a kqkp are a draw. If a computer has this knowledge it can trade into this position instead of playing into a loss. The bishop pawn comes to mind. To my way of thinking this is knowledge that will help save a draw instead of losing. Do you not believe this? Jim
