7 Card Stud will seat a maximum of eight players to a table. All eight players will put in an ante, before they receive their cards. The antes vary from site to site, and a sites ante structure is very important, as it can change the way you play a game. For example, you would play a lot looser in Party Poker's $0.5/$1 ante structure as opposed to Paradise Poker's ante structure, where you could play incredibly tight.
All players must first ante up, and then they are dealt three cards, two down, one face up for everyone to see. The player with the lowest up-card will be the bring-in, who is forced to initiate the action with a bet. If two players or more have the same lowest card, it is ranked by suits, in the order of Spades, Hearts, Diamonds and Clubs. So if everyone were showing a deuce, the two of clubs would be the bring-in.
This betting round is known as third street. There will be five betting rounds in total in Stud. Every subsequent street, the highest hand will initiate the betting. If both people have the same hand(for example two are showing a pair of aces), then the player to the left of the dealer is first to act.
As per standard poker rules, you can either call the bring-in, raise the bring-in to a full bet, or fold. Each bet and raise on third street and fourth street is known as a small bet, for example in $1/$2 it would be a $1 raise.
On 4th street, if a player pairs their upcard, known as their door card, on most sites they have the option of betting double, betting single, or just checking. On 5th to 7th street, the betting is set at the highest end of the limit structure.
Depending on the site, there may or may not be a cap to betting heads-up. Numerous sites, including InterPoker and Fortune Poker have no cap.
The question that is most commonly asked about Stud is this: What if all 8 players stay in until the river? It's a good question; with 52 cards in the deck and 8 players receiving 7 cards each, there would have to be 56 cards. So if 8 players are still in it at 7th street, a community card is dealt in the middle of the table, and all players can use that card. Here is a screenshot of this happening:
7 Card Stud is generally a limit game, however it is currently available in a pot limit variant on the Prima Poker Network. We recommend Golden Tiger Poker and Royal Vegas Poker on that network.
7 Card Stud also has a hi-lo variant which is very popular. Usually an 8 qualifier, as per Stud rules, the player uses 5 of his 7 cards to make the best hand. However in Stud Hi/Lo, if there is a Low qualifier, the High & Low will split the pot. For example if someone has a pair of aces, and their opponent has 23467, then it will split. However the low hand can also scoop the pot, by winning both high and low, with for example 23456, or the more popular steel wheel, which is a straight flush A-5.
