Ukimix: I sense problems here because of the disadvantage condition. I can be kind of variable, e.g. one player has less pieces (ergo, the disadvantage), then manages to capture some opponent's pieces and turn the advantage to own side, etc.
It would be nice if some Thai players give us an enlightenment on this.
(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)
