Good question. Reasons can be many. One example: If a processor so now and then makes an error in the evaluation function of a chess program the evaluation is wrong. If the node (with the wrong score) is an unimportant one you will notice nothing. If the node is an important one (such as a forced move) while the score is wrong this will influence its main-line. If such errors are happening enough times this will lead to an inferior move. But mostly it will not come that far. If a processor makes mistakes it is more likely the running software is going to crash. Ed Schroder >Thanks, >Jeff
