I am playing someone who had his vacation flag up when he challenged me, and continues to keep it up while playing. He has over 300 games in progress, and he uses the vacation flag to keep from timing out. He only moves after time is out, and I can't claim the timeout win because of his vacation flag. I think this is an abuse of the vacation flag, and I wish RHP would change the rules to keep this from happening. He is in a deep hole in my game, and it's only a matter of time before he loses anyway, but boy, it's a pain to have to wait until he moves at leisure.
