Rules and history of poker

 Poker is a family of card games involving betting and individual play, whereby the winner is determined by the ranks and combinations of their cards, some of which remain hidden until the end of the game. Poker games vary in the number of cards dealt, the number of shared or "community" cards and the number of cards that remain hidden. The betting procedures vary among different poker games in such ways as betting limits and splitting the pot between a high hand and a low hand.

In most modern poker games, the first round of betting begins with one of the players making some form of a forced bet (the blind and/or ante). In standard poker, each player bets according to the rank he believes his hand is worth as compared to the other players. The action then proceeds clockwise as each player in turn must either match the maximum previous bet or fold, losing the amount bet so far and all further interest in the hand. A player who matches a bet may also "raise," or increase the bet. The betting round ends when all players have either matched the last bet or folded. If all but one player folds on any round, the remaining player collects the pot and may choose to show or conceal his hand. If more than one player remains in contention after the final betting round, the hands are revealed and the player with the winning hand takes the pot. With the exception of initial forced bets, money is only placed into the pot voluntarily by a player who either believes the bet has positive expected value or who is trying to bluff other players for various strategic reasons. Thus, while the outcome of any particular hand significantly involves chance, the long-run expectations of the players are determined by their actions chosen on the basis of probability, psychology and game theory.
Poker has gained in popularity since the beginning of the twentieth century, and has gone from being primarily a recreational activity confined to small groups of enthusiasts, to a widely popular spectator activity with international audiences and multi-million dollar tournament prizes.

History

English actor Joseph Cowell reported in his memoirs that the game was played in New Orleans, Louisiana 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 north along the Mississippi River and to the 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. The draw was added prior to 1850 (when it was first mentioned in print in a handbook of games). During the American Civil War, Pildid / - pokker 1many additions were made including stud poker (specifically five-card stud), 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).
Modern tournament play became popular in American casinos after the World Series of Poker (WSOP) began, in 1970. Notable champions from these early WSOP tournaments include Johnny Moss, Amarillo Slim, Bobby Baldwin, Doyle Brunson, and Puggy Pearson. Later in the 1970s, the first serious poker strategy books appeared, notably Super/System by Doyle Brunson and Caro's Book of Poker Tells by Mike Caro, followed later by The Theory of Poker by David Sklansky. By the 1980s, poker was being depicted in popular culture as a commonplace recreational activity. For example, it was featured in at least 10 episodes of Star Trek: The Next Generation as a weekly event of the senior staff of the fictional ship's crew. In the 1990s, poker and casino gambling spread across the United States, most notably to Atlantic City, New Jersey.
Poker's popularity experienced an unprecedented spike at the beginning of the 21st century, largely because of the introduction of online poker and hole-card cameras, which turned the game into a spectator sport. Not only could viewers now follow the action and drama of the game on television, they could also play the game in the comfort of their own home.
Following the surge in popularity, new poker tours soon emerged, notably the World Poker Tour and European Poker Tour, both televised and the latter sponsored by online poker company PokerStars. Subsequent tours have since been created by PokerStars, such as Latin American Poker Tour and Asia Pacific Poker Tour, as well as other national tours.
In 2009 the International Federation of Poker was founded in Lausanne, Switzerland, becoming the official governing body for poker and promoting the game as a mind sport. In 2011 it announced plans for two new events: The Nations Cup, a duplicate poker team event, to be staged on the London Eye on the banks of the River Thames and “The Table”, the invitation only IFP World Championship, featuring roughly 130 of the world’s best poker players, in an event to find the 2011 official "World Champion".

Gameplay

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. The cards are dealt clockwise around the poker table, one at a time.
One or more players are usually required to make forced bets, usually either an ante or a blind bet (sometimes both). The dealer shuffles the cards, the player on the chair to their right cuts, and the dealer deals the appropriate number of cards to the players one at a time, beginning with the player to their left. 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 one player bets and no opponents choose to call (match) the bet and all opponents instead fold, the hand ends immediately, the bettor is awarded the pot, no cards are required to be shown, and the next hand begins. This is what 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. A poker hand comprises five cards; in variants where a player has more than five cards, the best five cards play.

List of poker hands

In poker, players construct hands of five cards according to predetermined rules, which vary according to which variant of poker is being played. These hands are compared using a hand ranking system that is standard across all variants of poker, the player with the highest-ranking hand winning that particular deal in most variants of poker. In some variants, the lowest-ranking hand can win or tie.
These hand rankings are also used in some other card games, and in poker dice.
The ranking of a particular hand is increased by including multiple cards of the same card rank, by all five cards being from the same suit, or by the five cards forming a consecutive series. The relative ranking of the various hand categories is based on the probability of being randomly dealt such a hand from a well-shuffled deck.
