Yeah ... BuiderQ seems right. Until we have a mathematical prove of the second player advantages we should keep it the way it is now. Anyway ... I'll keep on accepting invitations for double games (or maybe games where I'm not the first one to move :)))).
(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)
