playBunny: I don't think colors are randomly assigned. It looks to me like the challenger always makes the first move.
But random color assignment would be a decent system. Even if a game is tilted heavily in favor of one color (Maharajah chess, anyone?), the combined procedure of first randomly assigning colors to the players and then playing the game is fair.
