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?"
