POKER JARGON

The large and growing jargon of poker includes many terms. This page contains brief definitions of the most common terms you may encounter in text or at play. If possible, a link to a more complete article on the topic is given. Though space is not an issue here, the list has been trimmed to primarily those poker-specific terms one might find in poker texts or in common use in casinos.

Various poker hands have been given many names, and these are listed in List of slang names for poker hands. Finally, this is not meant to be a formal dictionary; precise usage details and multiple closely related senses are omitted here in favor of concise treatment of the basics.

Action button
A marker similar to a kill button, on which a player places an extra forced bet. Typically in a stud game, a player is 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.

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.

Buy-in
The minimum required amount of chips 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 to play. 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.

Drawing dead
Playing a drawing hand that will lose even if successful (a state of affairs usually only discovered after the fact or in a tounament when two or more players are "all in" and they show their cards). I caught the jack to make my straight, but Rob had a full house all along, so I was drawing dead.

Expected value, EV
In probability theory, the overall expected payoff of a particular event, calculated by multiplying the probability of each possible outcome by the payoff from each. For example, if there are two possible outcomes from an event (say, flipping a coin), one of which pays $2 and the other of which pays nothing, your EV for the event is $1 (in the long run, if this event happened many times, you would average $1 per event). In poker, one generally associates an EV with a particular action. One's EV from calling a bet, for example, is the sum of all possible outcomes from calling the bet multiplied by the probability of each. Note that since a bet costs money to make, the payoff of some outcomes--and therefore the EV itself--may be negative.
