Nothingness: if you resign after bearing off at least one, it will be 3-0... otherwise it will be 5-0 (or 7-0 if you're pieces are still in opponents area).
So get one piece off first, then resign if you can't mathematically win.
(hide) If you want to play a game with an opponent of a similar level, you can define a required BKR range for a new game invitation. Then nobody with a BKR outside this range will be able to see/accept it. (Katechka) (show all tips)
