Poker is a card game played between two or more players and involving betting. It is a fast-paced game and betting continues until one player has all the chips or everyone else folds. Players place their bets into a central pot called the “pot.” The highest hand wins the pot. Players may also bluff, which means that they make bets with a weak hand and hope to fool the other players into thinking they have a strong hand.
The game is traditionally played with a standard 52-card pack, sometimes supplemented by one or two jokers. In many clubs and among the best players, two packs of contrasting colors are used in order to speed up dealing. The dealer of the current deal assembles all of his cards from the pack he dealt, shuffles them and offers them to his opponent to his right for a cut. If the opponent declines, any other player may cut.
Each player must ante something into the pot (amount varies by game; our games are typically a nickel) in order to get their cards dealt. After this, each player places his bet into the pot. In some games, a player may check, meaning that they do not raise their bet during this interval; however, in most games, raising is allowed.
A player’s bet can be raised by either matching or increasing the amount staked by the previous active player. A player who raises the bet by exactly the amount of the last player is said to call. A player who raises the bet higher than that of the previous bettor is said to raise.
Several types of hands can be made, the most common being a straight and a pair. A pair is two identical cards and a straight is three or more consecutive cards in the same suit. The rank of a hand is determined by its odds, with the highest being five of a kind, beating fours of a kind and threes of a kind. In cases where the ranks of the cards are equal, ties are broken by the highest unmatched card or secondary pairs (in a full house).
In some games the high and low cards have different rank values. For example, an Ace high straight beats a seven low straight and an eight high flush beats a six low flush. In some games, there are wild cards, which can be placed in any position to change the ranking of a hand.
Poker has been derived from a wide variety of earlier vying games. The earliest examples of this are the games Belle, Flux and Trente-un (16th and 17th centuries), Post & Pair (17th – 18th centuries), Brelan (18th century to present) and Bouillotte (19th century). The history of poker is closely related to that of other card games. A large amount of research has been conducted into the origins and varieties of poker, and a set of rules has emerged based on probability, psychology and game theory.
