If you're going to play someone online, at least have the decency to finish your game. Something comes up you can at least tell your opponent. The last two games I have had the other player has quit without a word. Tacky!
I would even accept them to tell me that I'm kicking their ass and its pointless. I would tell them its a learning experience and to try to stick with it.
Another thing, before you come online, figure out how to get a name in there instead of player.
