My point remains: you haven't accomplished anything with your change. 
Maybe you meant to say that "you have lost the game" should be changed 
to "your king has been captured"? The idea being that this rule combined 
with the fact that players must not let their king get captured would 
cause some difference in the legality of moves.

Well I just described the interpretation I used. My move generator only 
generates orthodox-legal moves and I didn't want to muck with it.
