Poker a-zText Box: A
ace-to-five, ace-to-six 
Methods of evaluating low hands. See ace-to-five low, ace-to-six low. 
act 
To make a play (bet, call, raise, or fold) at the required time. It is Ted's turn to act. Compare to "in turn". 
action 
A player's turn to act. The action is on you. 
A willingness to gamble. I'll give you action or There's plenty of action in this game 
A bet, along with all the calls of that bet. For example, if one player makes a $5 bet and three other players call, he is said to have $5 "in action", and to have received $15 worth of action on his bet. Usually this term comes into play when figuring side pots when one or more players is all in. See table stakes. 
action button 
A marker similar to a kill button, on which a player places an extra forced bet. In a seven-card stud high-low game, the action button is awarded to the winner of a scoop pot above a certain size, signifying that in the next pot, that player will be required to post an amount representing a completion of the bring-in to a full bet. For example, in a stud game with $2 and $4 betting limits and a $1 bring-in, a player with the action button must post $2; after the cards are dealt, the player with the low card must still pay the $1 bring-in, then when the betting reaches the player who posted the $2, he is required to leave it in as a raise of the bring-in (and has the option to raise further). Players in between the bring-in and the action button can just call the bring-in, but they know ahead of time that they will be raised by the action button. 
action card 
In Texas hold 'em or other community card games, a card appearing on the board that causes significant betting action because it helps two or more players. For example, an ace on the flop when two players each hold an ace. 
action only 
In many cardrooms, with respect to an all-in bet, only a full (or half) bet can be reraised. Anything less than a full (or half) bet is considered to be action only, that is, other players can call the bet but not raise it. For example, Alice bets $100. Bob calls. Carol goes all in for $119. When the action returns to Alice and Bob, they may only call the extra $19; they cannot raise it. Carol's raise is called action only. Compare to "full bet rule", "half bet rule". 
active player 
A player still involved in the pot. If there are side pots, an all-in player may be active in some pots, but not in others. 
add-on 
In a live game, to buy more chips before you have busted. In tournament play, a single rebuy for which all players are eligible regardless of their stack size. This is usually allowed only once, at the end of the rebuy period. The add-on often offers more chips per dollar invested than the buyin and rebuys. Compare with "rebuy". 
advertising 
To make an obvious play or expose cards in such a way as to deliberately convey an impression to your opponents about your style of play. For example, to make a bad play or bluff to give the impression that you bluff frequently (hoping opponents will then call your legitimate bets) or to show only good hands to give the impression that you rarely bluff (hoping opponents will then fold when you do). 
aggressive, aggression 
See aggression (poker). Compare to "loose", "tight", "passive". 
air 
In a lowball game, "giving air" is letting an opponent who might otherwise fold know that you intend to draw one or more cards to induce him to call. 
all in 
Having bet all of your chips in the current hand. See all in. 
angle 
A technically legal, but borderline unethical, play. For example, deliberately miscalling one's own hand to induce a fold, or placing odd amounts of chips in the pot to confuse opponents about whether you mean to call or raise. A player employing such tactics is called an "angle shooter". 
ante 
A small amount of chips placed into the pot before each hand. This acts as a "tax" for playing hands and is usually used in Stud games, whereas Hold'em games usually have blinds
ante off 
In tournament play, to force an absent player to continue paying antes, blinds, bring-ins, or other forced bets so that the contest remains fair to the other players. Go ahead and take that phone call. We'll ante you off until you get back. Also "blind off". 

B
backdoor 
A draw requiring two or more rounds to fill. For example, catching two consecutive cards in two rounds of seven-card stud or Texas hold 'em to fill a straight or flush. 
A hand made other than the hand the player intended to make. I started with four hearts hoping for a flush, but I backdoored two more kings and my trips won. 
back in 
To enter a pot by checking and then calling someone else's open on the first betting round. Usually used in games like Jackpots, meaning to enter without openers. 
back into 
To win a pot with a hand that would have folded to any bet. For example, two players enter a pot of draw poker, both drawing to flushes. Both miss, and check after the draw. The player with the ace-high draw "backs into" winning the pot against the player with only a king-high draw. Also to make a backdoor draw, for example, a player who starts a hand with three of a kind, but makes a runner-runner flush, can be said to back into the flush. 
backraise 
A reraise from a player that previously limped in the same betting round. I decided to backraise with my pocket eights to isolate the all-in player. Also limp-reraise. 
bad beat 
A bad beat is a loss in which the losing player had the better odds on the winning player earlier in the hand. In general, the term is used when all the chips go in the pot when the losing player had odds. To take a bad beat means to be on the losing end of a bad beat; to lay a bad beat means to be on the winning end of a bad beat.
bank 
Also called the house, the person responsible for distributing chips, keeping track of the buy-ins, and paying winners at the end of the game. 
bankroll 
The amount of money that a player has to wager for the duration of his or her poker career. 
A very chip or money rich player. 
behind 
Not (currently) having the best hand. I'm pretty sure my pair of jacks was behind Lou's kings, but I had other outs, so I kept playing. 
Describing money in play but not visible as chips in front of a player. For example, a player may announce "I've got $100 behind" while handing money to a casino employee, meaning that he intends those chips to be in play as soon as they are brought to him. 
bet 
Any money wagered during the play of a hand. 
More specifically, the opening bet of a betting round. 
In a fixed limit game, the standard betting amount. There were six bets in the pot when I called. 
betting structure 
The complete set of rules regarding forced bets, limits, raise caps, and such for a particular game. See betting (poker). 
big bet 
The larger bet in a fixed-limit game. For example, in a $10-$20 game, the $10 bet is the small bet and the $20 bet is the big bet
big bet game 
A game played with a no limit or pot limit betting structure. 
big blind 
The larger of the two forced bets preflop. The person in second position posts the big blind, which is equivalent to a small bet. See also: Small Blind, Blinds.
blank 
A card, frequently a community card, of no apparent value. I suspected Margaret had a good draw, but the river card was a blank, so I bet again. Compare to "rag", "brick", "bomb". 
blaze 
A Non-standard poker hand of five face cards that outranks a flush. 
blind 
A type of forced bet. See blind (poker). 
In the "dark". 
Blinds
These are the forced bets that take the place of an ante. The person to the left of the dealer must pay the small blind and the person after him must pay the big blind.
blind stud 
A stud poker game in which all cards are dealt face down. Was popular in California before legal rulings made traditional stud legal there. 
blind off, blinded 
To "ante off". 
To have one's stack reduced by paying ever increasing blinds in tournaments. Ted had to make a move soon or he would be blinded away in three more rounds. 
blocker 
In community card poker, refers to holding one of the opponent's outs, typically when the board threatens a straight or straight draw. The board was A23 but with my pair of fives I held two blockers to the straight. Compare to "dry ace". 
bluff 
To bluff means to make a bet that you hope is not called by your opponents. The aim of a bluff is to win a pot because everyone else folds.
board 
The set of community cards in a community card game. If another spade hits the board, I'll have to fold. 
The set of face-up cards of a particular player in a stud game. Zack's board didn't look too scary, so I bet into him again. 
The set of all face-up cards in a stud game. I started with a flush draw, but there were already four other diamonds showing on the board, so I folded. 
both ways 
Both halves of a split pot, often declared by a player who thinks he or she will win both low and high. 
bottom end 
The lowest of several possible straights, especially in a community card game. For example, in Texas hold 'em with the cards 5-6-7 on the board, a player holding 3-4 has the bottom end straight, while a player holding 4-8 or 8-9 has a higher straight. Also "idiot end". 
bottom pair, bottom set 
In a community card game, a pair (or set) made by matching the lowest-ranking board card with one (or two) in one's private hand. Compare second pair, top pair. 
box 
The chip tray in front of a house dealer, and by extension, the house dealer's position at the table. You've been in the box for an hour now; don't you get a break? 
boxed card 
A card encountered face-up in the assembled deck during the deal, as opposed to one overturned in the act of dealing. Most house rules treat a boxed card as if it didn't exist; that is, it is placed aside and not used. Different rules cover cards exposed during the deal. 
break 
In a draw poker game, to discard cards that make a made hand in the hope of making a much better one. For example, a player with J-J-10-9-8 may wish to break his pair of jacks to draw for the straight, and a lowball player may break his 9-high 9-5-4-2-A to draw for the wheel. In a Jacks-or-better draw game, a player breaking a high pair must keep the discarded card aside, to prove he had openers. 
To end a session of play. The game broke at about 3:00. 
During a tournament, an interval where play ceases and the players are free to refresh or relieve themselves. 
brick 
A "blank", though more often used in the derogatory sense of a card that is undesirable rather than merely inconsequential, such as a card of high rank or one that makes a pair in a low-hand game. Also known as a bomb. Compare to "rags". 
brick & mortar 
A brick & mortar or B&M casino is a term referring to a "real" casino based in a building, as opposed to an online casino. This term is used to refer to many real world locations vs. their Internet counterparts. It is not just a poker term. 
bridge order 
Poker is neutral about suits. A spade flush and a club flush with all ranks matching is a tie. But in determining the dealer at the start of a game, or in determining the bringin bettor in a stud game, bridge rank rules: Spades beat hearts beat diamonds beat clubs. It's convenient that this works out to alphabetical order. 
bring in 
To open a betting round. Alice brought it in for $4, and Bob raised to $10. 
A forced bet in stud games. In the first betting round, the holder of the worst (lowest or highest, depending) upcard must post a bring in bet. The bring in bet is typically a quarter to a third of a small bet. The bring in bettor may look at his cards, and place a full bet if he deems it wise. 
brush 
A casino employee whose job it is to greet players entering the poker room, maintain the list of persons waiting to play, announce open seats, and various other duties (including brushing off tables to prepare them for new games, hence the name). 
To recruit players into a game. Dave is brushing up some players for tonight's game. 
bubble 
The last finishing position in a poker tournament before entering the payout structure. He was very frustrated after getting eliminated on the bubble. Also can be applied to other situations like if six players will make a televised final table the player finishing seventh will go out on the "TV bubble". Also used to describe any situation close to the payout structure. 
buck 
See button (poker). 
bug 
See bug (poker). Compare to wild card (poker). 
burn, burn card 
See burn card. 
busted 
Not complete, such as four cards to a straight that never gets the fifth card to complete it. 
Out of chips. To "bust out" is to lose all of one's chips. 
button 
Also "buck" or "hat". 
At most casinos, the players themselves do not deal the cards. Therefore, a button is used to indicate who is in the dealer's seat. Except in the preflop round, the player who is on the button acts last in a round of betting.
buy-in 
The minimum required amount of chips that must be "bought" to become involved in a game (or tournament). For example, a $4-$8 fixed limit game might require a player to buy at least $40 worth of chips. This is typically far less than an average player would expect to play with for any amount of time, but large enough that the player can play a number of hands without buying more, so the game isn't slowed down by constant chip-buying. 
buy short 
To buy into a game for an amount smaller than the normal buy-in. Some casinos allow this under certain circumstances, such as after having lost a full buy-in, or if all players agree to allow it. 
buy the button 
A rule originating in northern California casinos in games played with blinds, in which a new player sitting down with the button to his right (who would normally be required to sit out a hand as the button passed him, then post to come in) may choose to pay the amount of both blinds for this one hand (the amount of the large blind playing as a live blind, and the amount of the small blind as dead money), play this hand, and then receive the button on the next hand as if he had been playing all along. See public cardroom rules (poker). 
A tactic most often used by late-position players: a raise to encourage the later and button players to fold, thus giving the raiser last position in subsequent betting rounds. 
buy the pot 
Making a bet when no one else is betting so as to force the other players to fold in order to win the pot uncontested.
