Poker, also called golden or five-card stud, is any of many card games where players bet over which hand has the best probability of winning, in accordance with those specific rules of the game. In most variations of poker, such as Texas Holdem and Omaha, each player contributes a hand or part of their hand to the table, so that all players are playing for the same hand. In five-card stud, each player contributes a hand or parts of their hand to the table. A “hand” in poker is an unbroken sequence of cards, consisting of two hands, both of which are played in order, followed by the same hand in the same manner.
Most variations of poker are played with a standard deck of 52 cards, with one card per deck, called the King, Queen, Jack and Deuce. Most variations also allow for the hand ranking, so that the highest ranking card in a deck (the King), is placed at the top of the deck, and follows thereafter, in order, the rest of the cards in the deck, in descending order of rank. Some variations of holdem allow the player to raise all his/her hand, if they think they have the chance to do so; for example, the Texas Holdem High Stakes variation allows the players to raise all their money, in case the cards are raised and after the Raise, all remaining players are forced to fold. The highest ranked player, at the end of the hand, wins.
Before the turn, betting is usually prohibited, except for the flop, where players may place bets before, during and after the turn. After the turn, betting may be allowed once each round, with the exception of the last round. In multi-round tournaments, players may place bets in any round, but the pot only increases by one for each round that passes without a bet being raised. When the last round is reached, then the pot is reduced to its current value, and the player with the most cards after everyone else has folded is the winner of the tournament.
