Essentials
There are 1326 distinct possible combinations of two hole cards from a standard 52-card deck in hold 'em, but since suits have no absolute value in this poker variant, many of these hands are identical in value before the flop. For example, A♥ J♥ and A♠ J♠ are identical in value, because each is a hand consisting of an ace and a jack of the same suit.
Therefore, there are 169 non-equivalent starting hands in hold 'em, which is the total count of 13 pocket pairs, 13 × 12 x 1 / 2 = 78 suited hands and likewise 78 unsuited hands (13 + 78 + 78 = 169).
These 169 hands are not equally likely. Hold 'em hands are sometimes classified as having one of three "shapes":
- Pairs, (or "pocket pairs"), which consist of two cards of the same rank (e.g. 9♠ 9♣). One hand in 17 will be a pair, P(pair) = 1/17.
- Alternative means of making this calculation
- First Step
- As confirmed above.
- There are 1326 possible combinations of opening hand.
- Second Step
- There are 6 different combos of each pair. 9h9c, 9h9s, 9h9d, 9c9s, 9c9d, 9d9s. Therefore, there are 78 possible combinations of pocket pairs (6 multiplied by 13 i.e. 22-AA)
- To calculate the odds of being dealt a pair
- 78 (the number of any particular pair being dealt. As above) divided by 1326 (possible opening hands)
- 78/1326 ≈ 0.0588 or 5.88%
- Suited hands, which contain two cards of the same suit (e.g. A♣ 6♣).
Probability of first card is 1.0 (any of the 52 cards) Probability of second hand suit matching the first: There are 13 cards per suit, and one is in your hand leaving 12 remaining of the 51 cards remaining in the deck. 12/51 ≈ 0.2353 or 23.53%
- Offsuit hands, which contain two cards of a different suit and rank (e.g. K♠ J♥). 70.59% of all hands are offsuit non-paired hands
Offsuit pairs = 78
Other offsuit hands = 936
It is typical to abbreviate suited hands in hold 'em by affixing an "s" to the hand, as well as to abbreviate non-suited hands with an "o" (for offsuit). That is,
- QQ represents any pair of queens,
- KQ represents any king and queen,
- AKo represents any ace and king of different suits, and
- JTs represents any jack and ten of the same suit.
In poker, the nut hand is the strongest possible hand in a given situation. The second-nut hand or third-nut hand may refer to the second and third best possible hands. The term applies mostly to community card poker games where the individual holding the strongest possible hand, with the given board of community cards, is capable of knowing that they have the nut hand.
In a poker game with more than one betting round, an out is any unseen card that, if drawn, will improve a player's hand to one that is likely to win. Knowing the number of outs a player has is an important part of poker strategy. For example, in draw poker, a hand with four diamonds has nine outs to make a flush: there are 13 diamonds in the deck, and four of them have been seen. If a player has two small pairs, and he believes that it will be necessary for him to make a full house to win, then he has four outs: the two remaining cards of each rank that he holds.
Omaha hold 'em is a community card poker game similar to Texas hold 'em, where each player is dealt four cards and must make their best hand using exactly two of them, plus exactly three of the five community cards. The exact origin of the game is unknown, but casino executive Robert Turner first brought Omaha into a casino setting when he introduced the game to Bill Boyd, who offered it as a game at the Las Vegas Golden Nugget Casino. Omaha uses a 52-card French deck. Omaha hold 'em 8-or-better is the "O" game featured in H.O.R.S.E.
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.
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.
In poker, the probability of each type of 5-card hand can be computed by calculating the proportion of hands of that type among all possible hands.
Big two is a card game of Cantonese origin. It is similar to the games of Zheng Shangyou, daifugō, president, crazy eights, cheat, and other shedding games. The game is very popular in East Asia and in Southeast Asia, especially throughout mainland China, Hong Kong, Vietnam, Macau, Taiwan, Indonesia, the Philippines, Malaysia and Singapore. It is played both casually and as a gambling game. It is usually played with two to four players, the entire deck being dealt out in either case. The objective of the game is to be the first to play off all of one's cards.
Non-standard poker hands are hands which are not recognized by official poker rules but are made by house rules. Non-standard hands usually appear in games using wild cards or bugs. Other terms for nonstandard hands are special hands or freak hands. Because the hands are defined by house rules, the composition and ranking of these hands is subject to variation. Any player participating in a game with non-standard hands should be sure to determine the exact rules of the game before play begins.
Tiến lên is a shedding-type card game originating in southern China and Vietnam. It may be considered Vietnam's national card game, and is also played in the United States, sometimes under the names Viet Cong, VC, Thirteen, or Killer.
Pusoy dos, a variation of big two, is a popular type of "shedding" card game that originates on the islands of the Philippines in Calauag, Quezon Province. The object of the game is to be the first to discard one's hand by playing them to the table. If one cannot be first to play all cards, then the aim is to have as few cards as possible. Cards can be played separately or in certain combinations using poker hand rankings. Games of Pusoy Dos can be played by three or four people.
In community card poker, a player or hand is said to be counterfeited when a community card does not change the value of their hand, but makes it more likely that an opponent will beat it. This occurs primarily in Omaha hold 'em Hi-Lo split and sometimes in Texas hold 'em. Counterfeiting also occurs in the Badugi variant of draw poker.
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.
Poker hand A is said to dominate poker hand B if poker hand B has three or fewer outs that would improve it enough to win. Informally, domination is sometimes used to refer to any situation where one hand is highly likely to beat another. The term drawing dead is used to denote a domination situation with zero outs.
In contract bridge, an overcall is a bid made after an opening bid has been made by an opponent; the term refers only to the first such bid. A direct overcall is such a bid made by the player seated immediately to the left of the opener, i.e. next in the bidding rotation; an overcall in the 'last seat', i.e. by the player to the right of opener, which is made after two intervening passes, is referred to as a balancing or protective overcall.
