One can move into a position in which the only allowed move for a particular piece on the following turn is an illegal one (moving back to the square it had vacated the previous turn). If that piece must be moved due to attrition, I would think it fair to agree that any player who moves into such a position and is subsequently forced to make an illegal move should resign even if it results from attrition caused by the opponent that turn. Naturally, our tactics would be affected to avoid getting into such a position. Unfortunately, however, such a position may otherwise be advantageous if the bug didn't allow illegal moves. Perhaps we should have a list of players who agree to resign a game in which they make an illegal move whether intentionally or inadvertantly.
