Annoying way to win!
I would only do it if I must leave the game, rather than resign. Or if my opponent has berated me such as you have.
If not, your taking a risk. What if YOUR time runs out?
But I know an even sneaker way to win! Checkmate you before you can act like a spilt child's

Why are you assuming threefold repetition draw does not work?
Your opponent is probably simply not claiming it

i highly doubt someone would do that at the beginning of a game.
But still a rather sour technique.

How do you claim?
Same button: it changes from an "Offer Draw" to a "Claim Draw" if a three fold repetition applies. Or if the 50 move rule applies. People often assume it's automatic, when it's not.
It's not an automatic draw OTB either.

3-fold still works regardless of whether you've rejected a draw in the past. It just has to be claimed.

yes you should do it. this server has some wankers who try to force repetition which makes their opponent forfeit 4 points. This is a great hack to protect you from those wankers pullin' that crap anymore.

Yes... that's how it works. Every time a game ends in repetition, both sides lose 4 points.
