Poker is a family of comparing card games in which players wager 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. 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 the game of poker, a betting round is said to be closed if no player will have the right to raise in the round. Normally this occurs when a player calls, and the next player whose turn it is to act is the one who made the last raise, so he cannot raise further. The round can also said to be closed before it has actually ended if there are still players remaining to act, but they will not be entitled to raise either because the last raise was a sub-minimum all-in raise or because the limit ("cap") on allowed raises has been reached.
In poker, pot odds are the ratio of the current size of the pot to the cost of a contemplated call. Pot odds are compared to the odds of winning a hand with a future card in order to estimate the call's expected value. The purpose of this is to statistically guide a player's decision between the options of call or fold. Raising is an alternative to place this decision on the opponent.
In the card game of poker, a bluff is a bet or raise made with a hand which is not thought to be the best hand. To bluff is to make such a bet. The objective of a bluff is to induce a fold by at least one opponent who holds a better hand. The size and frequency of a bluff determines its profitability to the bluffer. By extension, the phrase "calling somebody's bluff" is often used outside the context of poker to describe situations where one person demands that another proves a claim, or proves that they are not being deceptive.
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.
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.
Slow playing is a deceptive play in poker where a player bets weakly or passively with a strong holding. It is the opposite of fast playing. A flat call can be a form of slow playing. The objective of slow playing is to lure opponents into a pot who might fold to a raise, or to cause them to bet more strongly than they would if the player had played aggressively. Slow playing sacrifices protection against hands that may improve and risks losing the pot-building value of a bet if the opponent also checks.
Cheating in poker is any behavior outside the rules of poker that is intended to give an unfair advantage to one or more players.
The fundamental theorem of poker is a principle first articulated by David Sklansky that he believes expresses the essential nature of poker as a game of decision-making in the face of incomplete information.
Every time you play a hand differently from the way you would have played it if you could see all your opponents' cards, they gain; and every time you play your hand the same way you would have played it if you could see all their cards, they lose. Conversely, every time opponents play their hands differently from the way they would have if they could see all your cards, you gain; and every time they play their hands the same way they would have played if they could see all your cards, you lose.
The following outline is provided as an overview of and topical guide to poker:
A big bet (BB) is the larger of two fixed bet amounts in a fixed-limit poker game. A big bet is used in the final rounds of a game to increase the pot amount and thereby enable the possibility of a bluff. Big bets are generally double the wager of the initial or small bet. Any multi-round poker game can use big bets to standardize wagers while maintaining a sufficient risk-ratio to encourage bluffing. Casino poker tables use big bets to set a limit to the amount of money a patron can lose in each wager.
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 the Nepal, India, Bangladesh, Sri Lanka 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.
Cash games, also sometimes referred to as ring games or live action games, are poker games played with "real" chips and money at stake, often with no predetermined end time, with players able to enter and leave as they see fit. In contrast, a poker tournament is played with tournament chips worth nothing outside the tournament, with a definite end condition, and a specific roster of competitors.
Negative freeroll occurs in poker when a player places an all-in wager on a hand that can only either tie or lose. A negative freeroll is relatively common in low stakes amateur play, but in higher stakes play, it is considered a serious blunder to allow a negative freeroll on the final round of betting due to the amount of risk involved.
Advantage gambling, or advantage play, refers to legal methods used to gain an advantage while gambling, in contrast to cheating. The term usually refers to house-banked casino games, but can also refer to games played against other players, such as poker. Someone who practises advantage gambling is often referred to as an advantage player, or AP. Unlike cheating, which is by definition illegal, advantage play exploits innate characteristics of a particular game to give the player an advantage relative to the house or other players. While not illegal, advantage play is often discouraged and some advantage players may be banned by certain casinos.

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.
Poker is a popular card game that combines elements of chance and strategy. There are various styles of poker, all of which share an objective of presenting the least probable or highest-scoring hand. A poker hand is usually a configuration of five cards depending on the variant, either held entirely by a player or drawn partly from a number of shared, community cards. Players bet on their hands in a number of rounds as cards are drawn, employing various mathematical and intuitive strategies in an attempt to better opponents.
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.
