; family pot
A deal in which every (or almost every) seated player called the first opening bet.

; fast
Aggressive. I was afraid of too many chasers, so I played my trips fast.

; feeder
In a casino setting, a second or third table playing the same game as a "main" table, and from which players move to the main game as players there leave.

; fence-hopper
See "hop the fence".

; fill, fill up
To successfully draw to a full house, typically starting with two pair or three of a kind. Jerry made his flush when I was betting my kings up, but I filled on seventh street to catch up.

; fire
To make the opening bet of a round, following the same analogy by which chips are called "ammo". I called Ken's bet on fourth with a draw, but I bricked, and when he fired again I had to fold. or I think Randy suspected my earlier bet was a bluff, but when I fired a second shot he let it go.

; fish
An unskilled player, or an otherwise skilled player playing carelessly.

; five of a kind
A hand possible only in games with wild cards, defeating all other hands, comprising five cards of equal rank. See five of a kind.

; fixed limit, flat limit
A betting structure in which a player never chooses the amount to bet, only whether to bet a fixed amount or not. See fixed limit.

; flat call
A call, in a situation where one might be expected to raise. Normally I raise with jacks, but with three limpers ahead of me I decided to flat call.

; floorman, floorperson
A casino employee whose duties include adjudicating player disputes, keeping games filled and balanced, and managing dealers and other personnel. Players may shout "floor!" to call for a floorperson to resolve a dispute, to ask for a table or seat change, or to ask for some other casino service.

; flop
In a community card game, the first set of community cards dealt, and the betting round that follows. In Texas hold 'em and Omaha hold'em in particular, this involves a set of three community cards dealt before the game's second betting round.

; flop game
Community card game.

; flush
A hand comprising five cards of the same suit. See flush.

; fold
To relinquish one's cards, forfeiting any further interest in the pot for this deal. See fold.

; forced bet
Money that a player is required to place into the pot by the rules of the game. The three common forms are antes, blinds, and bring-ins.

; forced-move
In a casino where more than one table is playing the same game with thesame betting structure, one of the tables may be designated the "main" table,and will be kept full by requiring a player to move from one of the feeder tables to fill any vacancies. Players will generally be informed that their table is a "forced-move" table to be used in this way before they agree to play there. Also "must-move".

; forward motion
A house rule of some casinos states that if a player in turn picks up chips from his stack and moves his hand toward the pot ("forward motion with chips in hand"), this constitutes a commitment to bet (or call), and the player may not withdraw his hand to check or fold. Such a player still has the choice of whether to call or raise.

; foul hand
A hand that is ruled unplayable because of an irregularity, such as being found with too many or two few cards, having been mixed with cards of other players or the muck, having fallen off the table, etc. Compare "dead hand".

; four-flush
Four cards of the same suit. A non-standard poker hand in some games, an incomplete drawing hand in most. See "bobtail", "four-straight".

; four of a kind, fours
A hand containing four cards of equal rank. See four of a kind.

; four-straight
Four cards in rank sequence; either an open-ender or one-ender. A non-standard poker hand in some games, an incomplete drawing hand in most. See "bobtail", "four-flush".

; free card
A card dealt to one's hand (or to the board of community cards) after a betting round in which no player opened. One is thereby being given a chance to improve one's hand without having to pay anything. I wasn't sure my hand was good, by I bet so I wouldn't give a free card to Bill's flush draw.

; freeroll
  1. A situation in which a player is guaranteed to at least break even and may possibly profit. Common in split-pot games. See freeroll.
  2. A tournament with no entry fee. Sometimes offered as a casino promotion, or as a reward for earlier play.

; freezeout
A winner-take-all tournament. That is, a game in which play continues until one player has all the chips.

; full, full boat, full hand, full house
A hand with three cards of one rank and two of a second rank. The term "full hand" seems to have been the original, but today "full house" is standard. See full house, "boat", "tight".

; full bet rule
In some casinos, the rule that a player must wager the full amount required in order for his action to constitute a raise. For example, in a game with a $4 fixed limit, a player facing an opening bet of $4 who wagers $7 is deemed to have flat called, because $8 is required to raise. The alternative is the "half bet rule".
