A game of Texas hold 'em in progress. "Hold 'em" is a popular form of poker.
Poker is a family of comparing card games in which playerswager over which hand is best according to that specific game's rules. It is played worldwide, but in some places the rules may vary. While the earliest known form of the game was played with just 20 cards, today it is usually played with a standard deck, although in countries where short packs are common, it may be played with 32, 40 or 48 cards.[1] Thus poker games vary in deck configuration, the number of cards in play, the number dealt face up or face down, and the number shared by all players, but all have rules that involve one or more rounds of betting.
In most modern poker games, the first round of betting begins with one or more of the players making some form of a forced bet (the blind or ante). In standard poker, each player bets according to the rank they believe their hand is worth as compared to the other players. The action then proceeds clockwise as each player in turn must either match (or "call") the maximum previous bet, or fold, losing the amount bet so far and all further involvement in the hand. A player who matches a bet may also "raise" (increase) the bet. The betting round ends when all players have either called the last bet or folded. If all but one player folds on any round, the remaining player collects the pot without being required to reveal their hand. If more than one player remains in contention after the final betting round, a showdown takes place where 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 a 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 increased in popularity since the beginning of the 21st century (2001) and has gone from being primarily a recreational activity confined to small groups of enthusiasts to a widely popular activity, both for participants and spectators, including online, with many professional players and multimillion-dollar tournament prizes.[2]
History
This article should include a better summary of History of poker. See Wikipedia:Summary style for information on how to properly incorporate it into this article's main text.(April 2018)
While poker's exact origin is the subject of debate, many game scholars point to the French game Poque and the Persian game As-Nas as possible early inspirations.[3] For example, in the 1937 edition of Foster's Complete Hoyle, R. F. Foster wrote that "the game of poker, as first played in the United States, five cards to each player from a twenty-card pack, is undoubtedly the Persian game of As-Nas." However, in the 1990s the notion that poker is a direct derivative of As-Nas began to be challenged by gaming historians including David Parlett. What is certain, however, is that poker was popularized in the American South in the early 19th century, as gambling riverboats in the Mississippi River and around New Orleans during the 1830s helped spread the game. One early description of poker was played on a steamboat in 1829 is recorded by the English actor, Joe Cowell. The game was played with twenty cards ranking from Ace (high) to Ten (low).[4]
In contrast to this version of poker, seven-card stud only appeared in the middle of the 19th century, and was largely spread by the US military.[5] It became a staple in many casinos following the second world war, and grew in popularity with the advent of the World Series of Poker in the 1970s.[6]
Texas hold 'em and other community card games began to dominate the gambling scenes over the next couple of decades. The televising of poker was a particularly strong influence increasing the popularity of the game during the turn of the millennium, resulting in the poker boom a few years later between 2003 and 2006. Today the game has grown to become an extremely popular pastime worldwide.
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, 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, distinguishing it from other vying games and from other games that use 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 available to them, only the best five-card combination counts. There are 10 different kinds of poker hands, such as straight flush and four of a kind.
Poker has many variations,[7][8] all following a similar pattern of play[9] and generally using the same hand ranking hierarchy. There are four main families of variants, largely grouped by the protocol of card-dealing and betting:
Straight
A complete hand is dealt to each player, and players bet in one round, with raising and re-raising allowed. This is the oldest poker family; the root of the game as now played was a game known as Primero, which evolved into the game three-card brag, a very popular gentleman's game around the time of the American Revolutionary War and still enjoyed in the U.K. today. Straight hands of five cards are sometimes used as a final showdown, but poker is almost always played in a more complex form to allow for additional strategy.
Cards are dealt in a prearranged combination of face-down and face-up rounds, or streets, with a round of betting following each. This is the next-oldest family; as poker progressed from three to five-card hands, they were often dealt one card at a time, either face-down or face-up, with a betting round between each. The most popular stud variant today, seven-card stud, deals two extra cards to each player (three face-down, four face-up) from which they must make the best possible 5-card hand.
Five-card draw: A complete hand is dealt to each player, face-down. Then each player must place an ante to the pot. They can then see their cards and bet accordingly. After betting, players can discard up to three cards and take new ones from the top of the deck. Then, another round of betting takes place. Finally, each player must show their cards and the player with the best hand wins.
Also known as "flop poker," community card poker is a variation of stud poker. Players are dealt an incomplete hand of face-down cards, and then a number of face-up community cards are dealt to the center of the table, each of which can be used by one or more of the players to make a 5-card hand. Texas hold 'em and Omaha are two well-known variants of the community card family.
There are several methods for defining the structure of betting during a hand of poker. The three most common structures are known as "fixed-limit," "pot-limit," and "no-limit." In fixed-limit poker, betting and raising must be done by standardized amounts. For instance, if the required bet is X, an initial bettor may only bet X; if a player wishes to raise a bet, they may only raise by X. In pot-limit poker, a player may bet or raise any amount up to the size of the pot. When calculating the maximum raise allowed, all previous bets and calls, including the intending raiser's call, are first added to the pot. The raiser may then raise the previous bet by the full amount of the pot. In no-limit poker, a player may wager their entire betting stack at any point that they are allowed to make a bet. In all games, if a player does not have enough betting chips to fully match a bet, they may go "all-in," allowing them to show down their hand for the number of chips they have remaining.
While typical poker games award the pot to the highest hand as per the standard ranking of poker hands, there are variations where the best hand, and thus the hand awarded the pot, is the lowest-ranked hand instead. In such games the best hand contains the lowest cards rather than the highest cards; some variations may be further complicated by whether or not hands such as flushes and straights are considered in the hand rankings. There are also games where the highest and lowest hands divide the pot between them, known as "high low split" games.
Other games that use poker hand rankings may likewise be referred to as poker. Video poker is a single-player video game that functions much like a slot machine; most video poker machines play draw poker, where the player bets, a hand is dealt, and the player can discard and replace cards. Payout is dependent on the hand resulting after the draw and the player's initial bet.
Strip poker is a traditional poker variation where players remove clothing when they lose bets. Since it depends only on the basic mechanic of betting in rounds, strip poker can be played with any form of poker; however, it is usually based on simple variants with few betting rounds, like five card draw.
Another game with the poker name, but with a vastly different mode of play, is called Acey-Deucey or Red Dog poker. This game is more similar to Blackjack in its layout and betting; each player bets against the house, and then is dealt two cards. For the player to win, the third card dealt (after an opportunity to raise the bet) must have a value in-between the first two. Payout is based on the odds that this is possible, based on the difference in values of the first two cards. Other poker-like games played at casinos against the house include three card poker and pai gow poker.
In a January 2015 article[10] published in Science, a group of researchers mostly from the University of Alberta announced that they "essentially weakly solved" heads-up limit Texas Hold 'em with their development of their Cepheus poker bot. The authors claimed that Cepheus would lose at most 0.001 big blinds per game on average against its worst-case opponent, and the strategy is thus so "close to optimal" that "it can't be beaten with statistical significance within a lifetime of human poker playing."[11]
Five-card draw is a poker variant that is considered the simplest variant of poker, and is the basis for video poker. As a result, it is often the first variant learned by new players. It is commonly played in home games but rarely played in casino and tournament play. The variant is also offered by some online venues, although it is not as popular as other variants such as seven-card stud and Texas hold 'em.
Twist is poker jargon for a round with specific rules which is sometimes used in the poker variant stud poker.
Red dog, also known as Yablon, is a game of chance played with cards, in which two cards are dealt and a player bets on whether the rank of a third card would fall between them. While found in some land casinos, its popularity has declined, although it is featured at many online casinos.
In the game of poker, the play largely centers on the act of betting, and as such, a protocol has been developed to speed up play, lessen confusion, and increase security while playing. Different games are played using different types of bets, and small variations in etiquette exist between cardrooms, but for the most part the following rules and protocol are observed by the majority of poker players.
Five-card stud is the earliest form of the card game stud poker, originating during the American Civil War, but is less commonly played today than many other more popular poker games. It is still a popular game in parts of the world, especially in Finland where a specific variant of five-card stud called Sökö is played. The word sökö is also used for checking in Finland.
Seven-card stud, also known as Seven-Toed Pete or Down-The-River, is a variant of stud poker. Before the 2000s surge of popularity of Texas hold 'em, seven-card stud was one of the most widely played poker variants in home games across the United States and in casinos in the eastern part of the country. Although seven-card stud is not as common in casinos today, it is still played online. The game is commonly played with two to eight players; however, eight may require special rules for the last cards dealt if no players fold. With experienced players who fold often, playing with nine players is possible.
Texas hold 'em is one of the most popular variants of the card game of poker. Two cards, known as hole cards, are dealt face down to each player, and then five community cards are dealt face up in three stages. The stages consist of a series of three cards, later an additional single card, and a final card. Each player seeks the best five-card poker hand from any combination of the seven cards: the five community cards and their two hole cards. Players have betting options to check, call, raise, or fold. Rounds of betting take place before the flop is dealt and after each subsequent deal. The player who has the best hand and has not folded by the end of all betting rounds wins all of the money bet for the hand, known as the pot. In certain situations, a "split pot" or "tie" can occur when two players have hands of equivalent value. This is also called "chop the pot". Texas hold 'em is also the H game featured in HORSE and HOSE.
Brag is an 18th century British card game, and the British national representative of the vying or "bluffing" family of gambling games. It is a descendant of the Elizabethan game of Primero and one of the several ancestors to poker, the modern version just varying in betting style and hand rankings. It has been described as the "longest-standing British representative of the Poker family."
Razz is a form of stud poker that is normally played for ace-to-five low. It is one of the oldest forms of poker, and has been played since the start of the 20th century. It emerged around the time people started using the 52-card deck instead of 20 for poker.
Bouillotte is an 18th-century French gambling card game of the Revolution based on Brelan, very popular during the 19th century in France and again for some years from 1830. It was also popular in America. The game is regarded as one of the games that influenced the open-card stud variation in poker. The rules continue to be printed in French gaming compendia.
Badugi is a draw poker variant similar to triple draw, with hand-values similar to lowball. The betting structure and overall play of the game is identical to a standard poker game using blinds, but, unlike traditional poker which involves a minimum of five cards, players' hands contain only four cards at any one time. During each of three drawing rounds, players can trade zero to four cards from their hands for new ones from the deck, in an attempt to form the best badugi hand and win the pot. Badugi is often a gambling game, with the object being to win money in the form of pots. The winner of the pot is the person with the best badugi hand at the conclusion of play. Badugi is played in cardrooms around the world, as well as online, in rooms such as PokerStars. Although it hasn’t had its own tournament per se at the WSOP, it is featured in the Dealers Choice events as well as in the Triple Draw Mix. The 2023 WSOP event does have a Badugi tournament scheduled.
Teen patti is a gambling card game. Teen Patti originated in India and is popular throughout South Asia. It originated in the English game of three-card brag, with influences from poker. It is also called flush or flash in some areas.
Guts is a comparing card game, or family of card games, related to poker. Guts is a gambling game involving a series of deals of 2, 3, or 4 cards. Hand are ranked similarly to hands in poker. The betting during each deal is simple : all players decide whether they are "in" or "out", and announce this at the same time. Each deal has its own showdown, after which the losers match or increase the pot, which grows rapidly. A round of the game ends when only one person stays in and wins the pot.
The following is a glossary of poker terms used in the card game of poker. It supplements the glossary of card game terms. Besides the terms listed here, there are thousands of common and uncommon poker slang terms. This is not intended to be a formal dictionary; precise usage details and multiple closely related senses are omitted here in favor of concise treatment of the basics.
Baduci is a combination of Badugi poker and deuce to seven triple draw, and uses hand values similar to lowball. The pot in this game is split much like high-low split between the best Badugi hand and the best 2-7 triple draw hand. The betting structure and overall play of the game is nearly identical to a standard poker game using blinds. A players' hand contains five cards, where only four cards are used to determine the best Badugi hand and five cards are used to determine the triple draw hand. During each of three drawing rounds, players can trade zero to five cards from their hands for new ones from the deck.
Stud poker is any of a number of poker variants in which each player receives a mix of face-down and face-up cards dealt in multiple betting rounds. Stud games are also typically non-positional games, meaning that the player who bets first on each round may change from round to round. The cards dealt face down to each individual player are called hole cards, which gave rise to the common English expression ace in the hole for any hidden advantage.
Draw poker is any poker variant in which each player is dealt a complete hand before the first betting round, and then develops the hand for later rounds by replacing, or "drawing", cards.
Community card poker refers to any game of poker that uses community cards, which are cards dealt face up in the center of the table and shared by all players. In these games, each player is dealt an incomplete hand face down, which are then combined with the community cards to make a complete hand. The set of community cards is called the "board", and may be dealt in a simple line or arranged in a special pattern. Rules of each game determine how they may be combined with each player's private hand. The most popular community card game today is Texas hold 'em, originating sometime in the 1920s.
Wall Street Poker is a form of stud poker which also features community cards. It is named after the financial district of New York and the movie of the same name, because of a strategy of aggressive bidding involved.
