There should be some way for tournaments to be set up with a limit on the number of moves played. This would be a *small* change in the rules of chess, but it should be an improvement from the point of view of the person(s) running the tournament. It would be kind of like a 50 move rule, except that you would require the games to end after a preset number of moves. If no mate, then call it a draw.
