Seat ( poker )

1) A chair at a poker table, or, more particularly, the player in that chair, or the seating position of that player. A house dealer might say to an approaching cocktail waitress, "Seat 1 wants a drink."
2) An opening in a poker game, particularly as it just becomes available for a new player. A dealer may announce to the floorman, "Seat open on 3." Someone who has not yet sat down to play may ask the board man, "Do you have a seat in 10-20 hold 'em?"
