Before each player makes one move the other can "abort" the game, meaning that there is no rating change or win/loss recorded.
Also, I think before 4 moves the other player can resign a game without a rating change but it is still recorded as a loss. Correct me if I'm wrong on this one.
I was involved in playing on line and my opponent "Aborted" the game. I can't find anything on this, can anyone be of assistance. Thank you.
