Heads-up poker is a form of poker that is played between only two players. It might be played during a larger cash game session, where the game is breaking up and only two players remain on the table, or where two players are trying to start a game and playing heads-up while waiting for other opponents. It is also a necessary phase in most sit-and-go (SNG) poker tournaments; the single remaining tournament winner will at some point have to face only a single opponent. Alternatively, heads-up poker may be played on purpose, either in a cash game format, or as a SNG, where two players play a winner-take-all tournament for a fixed, previously agreed upon amount of money. On larger online poker rooms and during certain tournament series, one may stumble upon larger heads-up tournaments, usually in the shoot-out format. Usually, in order to ensure the fairness of the game, all players finishing at the same level of the tournament bracket will be paid out the same amount of money, no matter what their finishing place is.
The rules of heads-up poker are the same as in a game with three or more players, except in community card poker, the blinds are usually reversed in order to decrease the positional advantage in matches between two players of similar skill. Nevertheless, the strategy employed tends to be vastly different from a multi-handed poker game. Since only two players take part in the hand, the chance of having the best hand is much higher than in a multi-handed game, which causes the game to become more aggressive than normal. Bluffs for example become easier to pull off in a heads-up game since it is only necessary to bluff a single opponent in order to win the pot, whereas in a multi-handed game there is a greater risk of someone having a big hand that cannot be bluffed.
The heads-up limit Texas hold'em variation has been claimed to be "essentially weakly solved" in January 2015 by the Cepheus poker-playing bot. [1] [2]
In poker tournaments heads-up poker is played as individual events and there are also heads-up championships. Heads-up poker tournaments are typically played as knock-out tournaments. An example of a heads-up tournament is the National Heads-Up Poker Championship.
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 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.
A poker tournament is a tournament where players compete by playing poker. It can feature as few as two players playing on a single table, and as many as tens of thousands of players playing on thousands of tables. The winner of the tournament is usually the person who wins every poker chip in the game and the others are awarded places based on the time of their elimination. To facilitate this, in most tournaments, blinds rise over the duration of the tournament. Unlike in a ring game, a player's chips in a tournament cannot be cashed out for money and serve only to determine the player's placing.
A computer poker player is a computer program designed to play the game of poker, against human opponents or other computer opponents. It is commonly referred to as pokerbot or just simply bot. As of 2019, computers can beat any human player in poker.
