LJ's suggestion is to have a game time limit - which as I understand it, for each minute you do not make a move, it takes away a minute.

So if you are given lets say 50 hours to make all your moves in a game, I was just showing how someone could watch and easly take away 23 hours from someone else, which would cause them to lose the game. (which is why the suggestion of a 24 hour grace before the main game timer starts).

And your are exactly right - if the tournament is set up, you probable do not want the person who moves daily to time out - which is what I was pointing out could happen! :-)
