Groucho: Sure, but if you're using it in as deliberate a manner as he seems to be doing then he will be checking in frequently to ensure that he always gets to make his move. He's relying on his opponents not being as on the bal about it as he is. In the relatively few matches that that's been the case, he's had an honest game on his hands.

It's the overwhelming number of matches that he's won by timeout that makes it looklike cheating. Any normal person would feel wrong winning so much that way and would stop using such a clock because it's so obviously unfair to others. Such wins are hollow victories to real people. You don't even need to check individual games as I did. Simply look at the finished games lists and see how many games are done with in a sprinkling of moves.
