I have just discovered a small bug which occurs when both a jump (capture) and a knight's charge (halma-like jumps followed by a capture) can be made with the same piece. It means that if BrainKing refuses to submit your move, please don't report it to the Bug Tracker and be patient. I am aware of it.
(hide) If you want to find an opponent with similar playing skills to your own look in the Ratings page of the type of game you want and find a player with a similar BKR. (pauloaguia) (show all tips)
