at IYT:
"If a game of Sabotage has a certain number of moves in a row with no captures, then the game is a draw. The number of moves varies according to the type of Sabotage game:

* Sabotage: 50 moves per player
* Sabotage Rush: 50 moves per player
* Mini Sabotage: 35 moves per player


These rules apply to Sabotage games which were started after 5/8/01."

I recommend listing a date for which games that were started before are exempt from the draw rule or at least the count is reset on that date for them.
