snigfarp: As for draws by repetition, I would be happy enough if a draw was mutually agreed by the players, rather than enforced by the rules. If an unsportsmanlike Swede attempts to win by attrition, making repetitive attacks while refusing the offer of a draw, it's simple enough on this site not to play against him (or her) in future.

But what if the person making the repetitive attack (assumed forced repetive attacks, other moves leading to a loss) does make a draw offer, and the offer gets refused? You'd either have to give up the game, or play forever, hoping the other side will time out at some point. It could hold up a tournament for quite a long time.

I think that especially on a game site like this, the rules should specific (draw, win, loss, ...) what happens if the game repeats itself.
