A card that would almost certainly make your hand best. If you are drawing at a straight, but there is a flush draw possible, then the cards that make your straight but also the flush are not clean outs.
To call more than one bet in a single action. For instance, suppose the first player to act after the big blind raises. Now any player acting after that must call two bets "cold." This is different from calling a single bet and then calling a subsequent raise.
A drawing hand (from the craps term).
A hand that is defined by all five cards -- a straight, flush, full house, four of a kind, or straight flush.
A hold'em starting hand in which the two cards are one apart in rank. Examples: KQs, 76.
A virtually unavoidable situation where two big hands get a lot of money in against each other.
To make your hand less valuable because of board cards that duplicate it. Example: you have 87 and the flop comes 9-T-J, so you have a straight. Now an 8 comes on the turn. This has counterfeited your hand and made it almost worthless.
To beat a hand -- typically a big hand. You hear this most often applied to pocket aces: "Third time tonight I've had pocket aces cracked."
As in "to cripple the deck." Meaning that you have most or all of the cards that somebody would want to have with the current board. If you have pocket kings, and the other two kings flop, you have crippled the deck.
A call that you make expecting to lose, but feel that you must make anyway because of the pot odds.
The position (or player) who acts one before the button.
(1) Money contributed to a pot by a player no longer in the pot. (2) A player in a tournament who has no realistic chance of winning.
Shortened form of "underdog."
A hand that will almost always lose to a better hand that people usually play. For instance, K3 is "dominated" by KQ. With the exception of strange flops (e.g., 3-3-X, K-3-X), it will always lose to KQ.
Getting unlucky in poker. The feeling that you can't win a hand. (Note: no actual "doomswitch" exists at any of the poker sites)
To play a hand that is not yet good, but could become so if the right cards come. Example: "I'm not there yet -- I'm drawing." Also used as a noun. Example: "I have to call because I have a good draw."
Trying to make a hand that, even if made, will not win the pot. If you're drawing to make a flush, and your opponent already has a full house, you are "drawing dead." Of course, this is a bad condition to be in.
Your "rightful" share of a pot. If the pot contains $80, and you have a 50% chance of winning it, you have $40 equity in the pot. This term is somewhat fanciful since you will either win $80 or $0, but it gives you an idea of how much you can "expect" to win.
(1) The amount you expect to gain on average if you make a certain play. For instance, suppose you put $10 into a $50 pot to draw at a hand that you will make 25% of the time, and it will win every time you make it. Three out of four times, you do not make your draw, and lose $10 each time for a total of $30. The fourth time, you will make your draw, winning $50. Your total gain over those four average hands is $50-$30 = $20, an average of $5 per hand. Thus calling the $10 has a positive expectation of $5. (2) The amount you expect to make at the poker table in a specific time period. Suppose in 100 hours of play, you win $527. Then your expectation is $5.27/hr. Of course, you won't make that exact amount each hour (and some hours you will lose), but it's one measure of your anticipated earnings.
A blind put in by a player just entering the game, returning to the game, or otherwise changing his position at the table. See also "blind" and "post."
A pot in which all (or almost all) of the players call before the flop.
To play a hand aggressively, betting and raising as much as possible. Example: "When you flop a set but there's a flush draw possible, you have to play it fast."
A poor player -- one who gives his money away. It's a well-known (though not well-followed) rule among good players to not upset the bad players, because they'll stop having fun and perhaps leave. Thus the phrase, "Don't tap on the aquarium."
The first three community cards, put out face up, all together.
The extra value you get from a hand when you force an opponent to fold. That is, if you don't have to see a showdown, your hand has more value than if you do.
A hand that may not be played for one reason or another. A player with a foul hand may not make any claim on any portion of the pot. Example: "He ended up with three cards after the flop, so the dealer declared his hand foul."
A turn or river card on which you don't have to call a bet because of play earlier in the hand (or because of your reputation with your opponents). For instance, if you are on the button and raise when you flop a flush draw, your opponents may check to you on the turn. If you make your flush on the turn, you can bet. If you don't get it on the turn, you can check as well, seeing the river card for "free."
One player has a shot at winning an entire pot when he is currently tied with another player. For instance, suppose you have Ac-Qc and your opponent has Ad-Qh. The flop is Qs-5c-Tc. You are tied with your opponent right now, but are free rolling, because you can win the whole pot and your opponent can't. If no club comes, you split the pot with him; if it does come, you win the whole thing.
A poker game that goes until one player amasses all the chips (or money) in play. Most big tournaments are played in "freezeout" fashion.
A starting hand with cards more than one rank apart. For instance, T9 is a one-gap hand. 86 is a two-gap hand.
