Why should a two-game match be forced?? If you think that's the only fair way to play, then refuse to play any single games and only play two-game matches. If someone wants to play a single game, why should you try and stop them?
(sakla) 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) (Bütün ipuçlarını göster)
