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.
One's number of outs is often used to describe a drawing hand: "I had a two-outer" meaning you had a hand that only two cards in the deck could improve to a winner, for example. In draw poker, one also hears the terms "12-way" or "16-way" straight draw for hands such as 6♥ 7♥8♠ (Joker), in which any of sixteen cards (4 fours, 4 fives, 4 nines, 4 tens) can fill a straight.
The number of outs can be converted to the probability of making the hand on the next card by dividing the number of outs by the number of unseen cards. For example, say a Texas Holdem player holds two spades, and two more appear in the flop. He has seen five cards (regardless of the number of players, as there are no upcards in Holdem except the board), of which four are spades. He thus has 9 outs for a flush out of 47 cards yet to be drawn, giving him a 9/47 chance to fill his flush on the turn. If he fails on the turn, he then has a 9/46 chance to fill on the river. Calculating the combined odds of filling on either the turn or river is more complicated: it is (1 - ((38/47) * (37/46))), or about 35%. A common approximation used is to double the number of outs and add one for the percentage to hit on the next card, or to multiply outs by four for the either-of-two case. This approximation works out to within a 1% error margin for up to 14 outs. [1]
Note that the hidden cards of a player's opponents may affect the calculation of outs. For example, assume that a Texas hold 'em board looks like this after the third round: 5♠ K♦ 7♦ J♠, and that a player is holding A♦ 10♦. The player's current hand is just a high ace, which is not likely to win unimproved, so the player has a drawing hand. He has a minimum of nine outs for certain, called nut outs, because they will make his hand the best possible: those are the 2♦, 3♦, 4♦, 6♦, 8♦, 9♦, and Q♦ (which will give him an ace-high flush with no possible better hand on the board) and the Q♣ and Q♥, which will give him an ace-high straight with no higher hand possible. The 5♦ and J♦ will also make him an ace-high flush, so those are possible outs since they give him a hand that is likely to win, but they also make it possible for an opponent to have a full house (if the opponent has something like K♠ K♣, for example). Likewise, the Q♠ will fill his ace-high straight, but will also make it possible for an opponent to have a spade flush. It is possible that an opponent could have as little as something like 7♣ 9♣ (making a pair of sevens); in this case even catching any of the three remaining aces or tens will give the player a pair to beat the opponent's, so those are even more potential outs. In sum, the player has 9 guaranteed outs, and possibly as many as 18, depending on what cards he expects his opponents to have.
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.
A poker player is drawing if they have a hand that is incomplete and needs further cards to become valuable. The hand itself is called a draw or drawing hand. For example, in seven-card stud, if four of a player's first five cards are all spades, but the hand is otherwise weak, they are drawing to a flush. In contrast, a made hand already has value and does not necessarily need to draw to win. A made starting hand with no help can lose to an inferior starting hand with a favorable draw. If an opponent has a made hand that will beat the player's draw, then the player is drawing dead; even if they make their desired hand, they will lose. Not only draws benefit from additional cards; many made hands can be improved by catching an out — and may have to in order to win.
In poker, pot odds are the ratio of the current size of the pot to the cost of a contemplated call. Pot odds are often compared to the probability of winning a hand with a future card in order to estimate the call's expected value.
In poker, a freeroll tournament is a tournament with no entry fee, and a freeroll hand is where a player is guaranteed to at least split the pot with his opponent, with a chance they can win the whole pot if certain final cards are dealt.
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.
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. Until the recent increase in popularity of Texas hold 'em, seven-card stud was the most widely played poker variant in home games across the United States, and in casinos in the eastern part of the country. Two to eight players is common, though eight may require special rules for the last cards dealt if no players fold. With experienced players who fold often, even 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 a "chop-pot".
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.
Suited connectors is a poker term referring to pocket cards that are suited and consecutive, for example Q♥ J♥. These hands are considered stronger than average because they have the highest potential to form straights and flushes when combined with the community cards.
In poker, bad beat is a subjective term for a hand in which a player with what appear to be strong cards nevertheless loses. It most often occurs where one player bets the clearly stronger hand and their opponent makes a mathematically poor call that wins with any subsequent dealing to complete the hand.
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.

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.
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.
Texas Shootout is a casino poker game based on Texas hold 'em developed by Galaxy Gaming. It is available in Las Vegas, and a number of smaller casinos in the U.S.
Six-plus hold 'em is a community card poker game variant of Texas hold 'em, where the 2 through 5 cards are removed from the deck. Each player is dealt two cards face down and seeks to make the best five card poker hand from any combination of the seven cards.
