ROFL.
Have you checked the FIDE rule book?
Absolutely. Make sure you also shoot your gun indoors, that's more or less convention.
It's more than fair. Some might even go so far as to say that if your opponent dies in the middle of a game that you get the win.
I would hardly want to win that way...but then,,,a win is a win.
Oh by the way I resent the remark about the hypothetical gun. Shame on you, aussie
