Add a new Dynastic rule, entitled “Cheating”, as follows:

Any player may once during a hand, replace one of eir cards with an Ace of Spades.  This player shall be referred to as the ‘Cheater’.  If the Cheater exposes their cards and wins that hand, then any player may make a post to the main blog accusing the Cheater of Cheating.  These two players shall then engage in a Shootout, according to the normal rules.  If the Cheater loses, then in addition to becoming Wounded, they shall run away and their Courage status shall be changed to Yellow, and the player with the next highest hand shall automatically win the pot.  If the Shootout is a draw, then the Cheater shall run away and their Courage status shall be changed to Yellow, and the player with the next highest hand shall automatically win the pot.  If the Cheater wins, then they shall win the pot as normal.  Only the first player to accuse the Cheater of Cheating shall engage in a Shootout. 

If a player accuses another player of Cheating, but that player claims innocence, then the dealer shall resolve such a dispute.  If the player claiming innocence was naturally dealt an Ace of Spades, then the accusing player shall have their Courage status changed to Yellow.  If, however, the player claiming innocence was indeed a Cheater, then the player with the next highest hand shall automatically win the pot, the rest of the Cheater’s money shall be taken by Uncle Sam, their Courage status shall be changed to Yellow, and Uncle Sam shall engage in a Shootout with the Cheater, which Uncle Sam shall automatically win, causing the Cheater to be Wounded.
