Mississippi Gonorrhea Rules

In Mississippi Gonorrhea, each player holds just two cards, one face down and one face up, and has three chances to exchange them, called breakfast, lunch and dinner, with a round of betting after the deal and after each exchange. The pot is split between the best high hand and the best low hand, but a pair of sevens wins the whole pot. Contributed by Robert Dier, as published on pagat.com.

Article 1Players, deck and objective

1.1

Mississippi Gonorrhea was contributed by Robert Dier and published on pagat.com. It is a two-card, high-low split draw game played with a standard 52-card deck and no wild cards.

1.2

The source sets no player limit. A player who exchanges both cards at every opportunity uses eight cards in all, so with more than six players the stock may run short. The dealer shall announce before the deal how discards are reused if that happens.

1.3

The object is to hold the best two-card high hand or the best two-card low hand at showdown, each of which wins half the pot, or to hold a pair of sevens, which wins it all.

Article 2Antes, the deal and the exchanges

2.1

Each player antes. The dealer deals each player two cards: one face down and one face up.

2.2

A round of betting follows the deal.

2.3

There are then three rounds of exchanges, called breakfast, lunch and dinner. At each one, every active player chooses one of these options:

2.3(a) exchange the face-down card for a new face-down card;

2.3(b) exchange the face-up card for a new face-up card; or

2.3(c) go to the library: exchange both cards for a new face-down card and a new face-up card (a full book).

2.4

The source does not say whether a player may keep both cards and make no exchange. The dealer shall announce before the deal whether standing pat is allowed.

2.5

A round of betting follows each exchange.

StageWhat happens
DealOne card down and one card up to each player, then betting
BreakfastFirst exchange, then betting
LunchSecond exchange, then betting
DinnerThird exchange, then betting
ShowdownBest high and best low split the pot; a pair of sevens takes it all

Article 3Showdown and splitting the pot

3.1

The pot is split equally between the best high hand and the best low hand. Players do not declare high or low.

3.2

Aces are always high, both for high and for low. The best high hand is a pair of aces (A-A). The best low hand is 3-2.

3.3

For high, any pair beats any two unpaired cards, and higher pairs beat lower pairs. Unpaired hands are compared by the higher card, then the lower.

3.4

For low, unpaired hands are compared by the higher card first, then the lower; the lower hand wins. Since 3-2 is the best low, a pair is not a good low hand.

3.5

Sevens hog. A pair of sevens wins the whole pot against any other hand, including a pair of aces. Taking the whole pot is called a hog.

3.6

The source does not say how the pot is shared if two players hold a pair of sevens, or if hands tie for high or low. The usual practice is to split the relevant share equally.

Example

A normal split

Player A: K♦K♠, a pair of kings.

Player B: 4♣2♥, four-two.

Player C: A♠Q♦, ace-queen.

Player A has the best high hand. For low, Player B's 4-2 beats Player C's A-Q, because aces are high. Players A and B each take half the pot.

Example

A pair of sevens takes everything

Player A: A♥A♦, a pair of aces. Player B: 3♠2♦, the best possible low. Player C: 7♣7♥.

Player C's pair of sevens wins the whole pot, beating both the best possible high and the best possible low.

Article 4Strategy notes

Half of each player's hand is on show, so opponents can see what each player is exchanging for. A player who keeps a face-up seven while exchanging the face-down card may be drawing to the pair of sevens.

Because aces are always high, an ace helps only a high hand. Low cards such as deuces and treys are mainly useful for low.

Going to the library gives the most new cards but throws away both current cards.

Article 5Frequently asked questions

What is the best hand in Mississippi Gonorrhea?

A pair of sevens. It wins the whole pot against any other hand, even a pair of aces. Otherwise the best high hand is A-A and the best low hand is 3-2.

What does 'going to the library' mean in Mississippi Gonorrhea?

Exchanging both of your cards at once, for a new face-down card and a new face-up card. The other options are to exchange only the face-down card or only the face-up card.

Are aces high or low in Mississippi Gonorrhea?

Always high. An ace is the best card for a high hand and the worst for a low hand.
