Euchre game variations their possession. Taking all five tricks here results in four points. Each player keeps their own score. A common variation played in southwestern England competitive pub leagues uses the standard Euchre deck with an extra card, usually a Joker or 2 of spades, called the "Benny" (often called the "Bird" in Australia). This card is the highest trump no matter what suit is called. When the Benny is turned over by the dealer, the dealer must choose a suit to call as trumps before looking at his or her hand. Bidding then proceeds normally. The Duchy of Cornwall lays claim
Revenue equivalence with the highest bid simply pays its bid, if all players bid using a bidding function formula_28, this is a Nash equilibrium. In other words, if each player bids such that they bid the expected value of second highest bid, assuming that theirs was the highest, then no player has any incentive to deviate. If this were true, then it is easy to see that the expected revenue from this auction is also formula_26 if formula_3 wins the auction. To prove this, suppose that a player 1 bids formula_31, effectively bluffing that its value is formula_32 rather than formula_9. We
