; aces and spaces

; action
  1. A player's turn to act. The action is on you.
  2. A willingness to gamble. I'll give you action or There's plenty of action in this game
  3. 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 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. 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.
