But when both repeat to perform a Grandmaster draw they're kind of destroying the value to spectators, as in any other sport the fans would revolt if both teams were so willing to not put up a struggle.
Some tournaments have had restrictions and incentives against this at least e.g. you won't get invited back if you have too many GM draws, or the game has to have a reasonable length and the arbiter won't allow such a draw, or they reset the pieces and make you start over if you draw too soon...
