Kuhn poker is a simplifed form of poker developed by Dr. Harold W. Kuhn, it is a zero sum two player game. The deck includes only three Playing cards, for example a King, Queen, and Jack. One card is dealt to each player, then the first player must bet or pass then the second player may bet or pass. If any player chooses to bet the opposing player must bet as well (call) in order to stay in the round. After both players pass or a bet the player with the highest card wins the pot. Kuhn demonstrated that there are many game theoretic optimal strategies for this game. For more information see "Simplified Two-Person Poker", by H. W. Kuhn.
