Plug ( poker )

1) A chip, a stack of chips, or a token of some sort (sometimes labeled "hold") set down by the house at any empty position to indicate that no one may sit there. The house may place a plug because a player has asked to hold his seat while he goes to get more cash, or because it wants to keep the seating arrangements balanced. For example, two draw tables have seven players each. The house may place a plug at each empty position so no one can move to the other game and leave one table with only six seats while the other is full. The floor man who puts a plug at an empty spot may not tell the players at the table that those chips do not represent a real player, leading some to wrongly think that the seat has been sold and someone will soon come to play those chips.
2) To place a plug; often followed by the seat designation. A floor man may say to the house dealer, "Plug the No. 2 seat, dealer."
