In the game of poker, opens and raises are considered aggressive plays, while calls and checks are considered passive (though a check-raise would be considered a very aggressive play). It is said[ by whom? ] that "aggression has its own value", meaning that often aggressive plays can make money with weak hands because of bluff value. In general, opponents must respond to aggressive play by playing more loosely, which offers more opportunities to make mistakes.
While it is true that aggressive play is generally superior to passive play, using any play exclusively can lead to predictability. A player who is constantly aggressive and plays many inferior hands is called a "maniac", and skilled players will take advantage of him by calling him more often, using isolation plays, and by other means.
If a player is not aggressive with his weaker hands, the opponents can safely fold whenever the player does bet or raise. The appropriate amount of aggression can be computed using game theory, and depends on the game being played and the tendencies of the opponents.
Most theorists, like David Sklansky and Doyle Brunson, suggest aggression as an important tool. Aggressive play should not be confused with loose play. Loose players may play passively, resulting in a calling station, while tight players may play aggressively, referred to as a TAG. Aggression is called for in particular circumstances. Very strong starting hands should be played very aggressively most of the time. A very strong propositional hand – one that is more likely to win with a straight or a flush – is one of the hands that can be played for effect with an aggressive style. Such aggression is deceptive, as the low and unpaired ranks of the starting hand require much improvement to win. This is beneficial for two reasons:
The second reasoning is what is known as "advertising" in poker. It can be very profitable for a player to convince the other players at the table that he is willing to gamble with less than premium cards. The result is larger pots when the aggressive player has tremendously strong hands.
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.
Blinds are forced bets posted by players to the left of the dealer button in flop-style poker games. The number of blinds is usually two, but it can range from none to three. When there are two blinds they are called the small blind and the big blind.
A check-raise in poker is a common deceptive play in which a player checks early in a betting round, hoping someone else will open. The player who checked then raises in the same round.
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 poker, a steal is a type of a bluff, a raise during the first betting round made with an inferior hand and meant to make other players fold superior hands because of shown strength. A steal is normally either an "ante steal" or "blind steal".
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.
A tell in poker is a change in a player's behavior or demeanor that is claimed by some to give clues to that player's assessment of their hand. A player gains an advantage if they observe and understand the meaning of another player's tell, particularly if the tell is unconscious and reliable. Sometimes a player may fake a tell, hoping to induce their opponents to make poor judgments in response to the false tell. More often, people try to avoid giving out a tell, by maintaining a poker face regardless of how strong or weak their hand is.
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.
Tilt is a poker term for a state of mental or emotional confusion or frustration in which a player adopts a suboptimal strategy, usually resulting in the player becoming overly aggressive. Tilting is closely associated with another poker term, "steam".
Morton's theorem is a poker principle articulated by Andy Morton in a Usenet poker newsgroup. It states that in multi-way pots, a player's expectation may be maximized by an opponent making a correct decision.
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.
In the game of poker, a kill game is a game played using a variation of fixed limit betting rules. A kill game provides for the play of kill hands, which involve an extra blind bet and increased betting limits. Kill games are infrequent but not uncommon in home poker games; many casinos offering poker will introduce the kill to a table on request or during certain scheduled times. Kills are most often used in community card poker variants like Texas hold 'em, which normally use blinds as the primary forced bet, and this article assumes such a game is being played, but the concept can be made to work with almost any poker variant with only minor changes to suit the betting protocol of the game.
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.

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.
