I think that may be what happened to Eo.
I have an opponent who doesn't want to move or resign :(

There's no rule against being a douche...
If there was, a significant fraction of the world's population would be under arrest.

The game is lost for black. For that not to happen white would need to make 2 or 3 really bad blunders. But that's very unlikely. Now, the guy has a rating close to 2000; obviously, he can see that the game is lost. Why won't he resign? Why won't he move?
He sounds like a time squatter they say "enjoy the wait" and let the clock run out in hopes their opponent will get discouraged and disconnect.
My advice is to wait out the time squatter but don't play him again!!

There's no rule against being a douche, and chess is full of such "characters", with myself included. Get used to it or go play barbies like a lil sissy! XD
That is a bad attitude for the promotion of chess...personally, I think we need more chess players in the world.

USE CONDITIONAL MOVES. THAT WILL MOVE THE GAME ALONG MUCH MORE QUICKLY. IF IT'S A LOST GAME, THEN IT SHOULD BE EASY.
Sometimes people need time to think or just chill with a cup of tea till the time is gone.
