i abort matches because:
1) i'm tired of waiting for white to make the first move
2) i accidently clicked on a match against an opponent i don't want to play against
3) i suddenly have to leave
(i don't give a crap about live ratings - that's where i play to fool around and try out new things)
EDIT: at 972 you are probably learning in every game you play. once you get rated higher, playing against someone lower than 1200 really doesn't teach you anything (except maybe patience).
I get a lot of aborted matches in live chess, especially when I accept a game with a player rated much higher than me (>1200). I am currently 972. Do people really abort matches with lower rated players to protect their rating. I don't know that I would care one way or another. I just enjoy playing. Regardless of my opponents rating, I find I always learn something. Maybe I will feel differently if I ever get up in the 1200's. Any thoughts?
