Seven-card stud

Seven-card stud, also known as Seven-Toed Pete or Down-The-River is a variant of stud poker. Until the recent increase in popularity of Texas hold 'em, seven-card stud was the most widely played poker variant in home games across the United States, and in casinos in the eastern part of the country. Two to eight players is common, though eight may require special rules for the last cards dealt if no players fold. With experienced players who fold often, even playing with nine players is possible.

In casino play, it is common to use a small ante and bring-in. In home games, it is typical to use an ante only.

Seven-card stud is the "S" game in HORSE and similar mixed game formats.

The game begins with each player being dealt two cards face down and one card face up. The player with the lowest-ranking upcard pays the bring-in, and betting proceeds after that in normal clockwise order. The bring-in is considered an open, so the next player in turn may not check. If two players have equally ranked low cards, suit may be used to break the tie and assign the bring-in (see high card by suit). If there is no bring-in, then the first betting round begins with the player showing the highest-ranking upcard, who may check. In this case, suit is not used to break ties. If two players have the same high upcard, the one first in clockwise rotation from the dealer acts first.

After the first betting round, another upcard is dealt to each player (after a burn card, and starting at the dealer's left as will all subsequent rounds), followed by a second betting round beginning with the player whose upcards make the best poker hand. Since fewer than five cards are face up, this means no straights, flushes, or full houses will count for this purpose. On this and all subsequent betting rounds, the player whose face-up cards make the best poker hand will act first, and may check or bet up to the game's limit.

The second round is followed by a third upcard and betting round, a fourth upcard and betting round, and finally a downcard, a fifth betting round, and showdown if necessary. Seven-card stud can be summarized therefore as "two down, four up, one down". Upon showdown, each player makes the best five-card poker hand he can out of the seven cards he was dealt.
