Stormerne: Is it really necessary to complicate the rules? I think, we could ignore the situation, that the black player fails to note that the king can reach the edge with the next move. So what's the difference whether black resigns immediately or just plays another move?
I would always vote for rules as simple as possible ...
(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)
