Usually the most revealing poker tells are based on the way a player habitually bets during particular situations. For example, maybe the player always checks when he has made the nuts, or a player may regularly fold after being re-raised.
U
| action | 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. | U |

| third man walking | A player who gets up from his seat in a cash game, after two other players are already away from the table, is referred to as the "third man walking".
