I believe that the OP was the cause of all this trouble. Your opponent has the right not to resign. You are only a 1200 and I've seen many 1200s stalemate with a rook, a knight and 4 pawns. So I don't think you are excluded from the list.
I don't know why are you even making such a fuss about this. Please be more mature. Thanks.
Actually I was ranked a 1333 at the time, and never have I stalemated with a rook & king v. a king.
Still, he doesn't know that. I can't really understand why you made this thread either. My only reasonable solution is that you are complaining because this person wasted your time. You could have saved your time by checkmating him quicker. It's your fault.
It's known as being a "Sore loser." people like that can't accept defeat, and feel that the only way they can get revenge is to run the clock down and possibly annoy their opponent. I like to get revenge if I lose a game, however, I resign when it's hopeless and offer a REMATCH. It's immature to run the clock down for no reason, and those people should be kicked out of chess.com
