Nothingness:
You previously said:
"That would be reasonable since that is the way it pretty much goes in chess. So 50moves without a capture of a piece..."
That isn't the site forcing a draw situation.
That is a player failing to make a capture to prevent a draw. "Enforce" is not the same as "force." Hence, the rules drive the strategy/tactics.
From my perspective, a player failing to make a capture in 50 moves is stalling. A 150 move game sounds exceptionally boring to me no less a 400 move game.
