Seven Card Stud
Seven-card stud is played with a starting hand of two downcards and one upcard dealt before the first betting round. There are then three more upcards and a final downcard, with a betting round after each, for a total of five betting rounds on a deal played to the showdown. The best five-card poker hand wins the pot. In all fixed-limit games, the smaller bet is wagered for the first two betting rounds, and the larger bet is wagered for the last three betting rounds (on the fifth, sixth, and seventh cards). If there is an open pair on the fourth card, any player has the option of making the smaller or larger bet. Deliberately changing the order of your upcards in a stud game is improper because it unfairly misleads the other players.
