Interesting. I feel like there needs to be a rule which forces a stalemate at some point. Currently the only rule is 'when the players agree,'... but if one of them refuses to agree the game could never end until one player just resigns in frustration.<p>In FIDE chess, there is a rule something along the lines of 'if no pawn moves are made within fifty consecutive turns, the game is a stalemate.' This game should probably have a rule like, 'if no piece crosses the center line within fifty consecutive turns, the game ends.'<p>Edit... thinking about this more, I really can't think of a situation where the player refusing the stalemate could possibly benefit.
