Pokerlings

The history of poker is a matter of debate. It closely resembles the Persian game of as nas, and may have been taught to settlers in New Orleans by Persian sailors. The name of the game likely descended from the Irish Poca (Pron. Pokah) ('Pocket') or even the French poque , which descended from the German pochen ('to brag as a bluff' lit. 'to knock'). Yet it is not clear whether the origins of poker itself lie with the games bearing those names. It is commonly regarded as sharing ancestry with the Renaissance game of primero and the French brelan. The English game brag (earlier bragg) clearly descended from brelan and incorporated bluffing (though the concept was known in other games by that time). It is quite possible that all of these earlier games influenced the development of poker as it exists now.

English actor Joseph Crowell reported that the game was played in New Orleans in 1829, with a deck of 20 cards and four players betting on which player's hand was the most valuable. Jonathan H. Green's book, An Exposure of the Arts and Miseries of Gambling (G. B. Zieber, Philadelphia, 1843), described the spread of the game from there to the rest of the country by Mississippi riverboats, on which gambling was a common pastime. As it spread up the Mississippi and West during the gold rush, it is thought to have become a part of the frontier pioneer ethos.

Soon after this spread, the full 52-card English deck was used, and the flush was introduced. During the American Civil War, many additions were made, including draw poker, stud poker (the five-card variant), and the straight. Further American developments followed, such as the wild card (around 1875), lowball and split-pot poker (around 1900), and community card poker games (around 1925). The spread of the game to other countries, particularly in Asia, is often attributed to the U.S. military.

The game and jargon of poker have become important parts of American culture and English culture. Such phrases and clichés as ace in the hole, ace up one's sleeve, beats me, blue chip, call one's bluff, cash in, high roller, pass the buck, poker face, stack up, up the ante, when the chips are down, wild card, and others are used in everyday conversation, even by those unaware of their origins at the poker table.

Beginning in 1970 a series of developments lead to poker becoming far more popular than it was previously:

Poker's popularity experienced an unprecedented spike at the beginning of the 21st century, largely because of the introduction of online poker and the invention of the hole-card camera, which turned the game into a spectator sport. Viewers could now follow the action and drama of the game, and broadcasts of poker tournaments such as the World Series of Poker and the World Poker Tour brought in huge audiences for cable and satellite TV distributors. Because of the increasing coverage of poker events, poker pros became more like celebrities, with poker fans all over the world entering into expensive tournaments for the chance to play with them. This increased camera exposure also brings a new dimension to the poker professional's game—the realization that their actions may be aired later on TV.

Major poker tournament fields have grown dramatically because of the growing popularity of online satellite-qualifier tournaments where the prize is an entry into a major tournament. The 2003 and 2004 WSOP champions, Chris Moneymaker and Greg Raymer, respectively, won their seats to the main event by winning online satellites.

In casual play, the right to deal a hand typically rotates among the players and is marked by a token called a 'dealer' button (or "buck"). In a casino, a house dealer handles the cards for each hand, but the button (typically a white plastic disk) is rotated clockwise among the players to indicate a nominal dealer to determine the order of betting.

One or more players are required to make forced bets to create an initial stake for which the players will contest. The dealer shuffles the cards, cuts, and deals the appropriate number of cards to the players one at a time. Cards may be dealt either face-up or face-down, depending on the variant of poker being played. After the initial deal, the first of what may be several betting rounds begins. Between rounds, the players' hands develop in some way, often by being dealt additional cards or replacing cards previously dealt. At the end of each round, all bets are gathered into the central pot.

At any time during a betting round, if a player makes a bet, opponents are required to fold, call or raise. If one player bets and no opponents choose to call (match) the bet, the hand ends immediately, the bettor is awarded the pot, no cards are required to be shown, and the next hand begins. Players may choose to check, this is where no one makes a bet and the next card is dealt. This possibility of winning a pot without showing a hand makes bluffing possible. Bluffing is a primary feature of poker, one that distinguishes it from other vying games and from other games that make use of poker hand rankings.

At the end of the last betting round, if more than one player remains, there is a showdown, in which the players reveal their previously hidden cards and evaluate their hands. The player with the best hand according to the poker variant being played wins the pot.
