Float
To float in poker means to make a call in order to stop a person from placing bluff bets. When a player is placing suspect continuation bets i.e. when an opponent assumes that a bettor may not have good cards despite placing a continuation bet after the flop, then to simply stop her/his progress and maybe even reveal her/his bluff, a player may make a call to her/his bet.
This takes away the pot from the aggressive player but that is something that will only happen if the bettor has been bluffing. For e.g. if a player with an A-K hand bets right out at the onset, after the blinds and continues to do so even after the flop, then that could mean one of two things. Either that player’s hand has improved after the reveal of the flop, or that the person is simply bluffing. To find out what the situation is, a player can risk calling the second bluff and that gives everybody on the table an opportunity to find out whether the player is actually bluffing or whether the flop has really made a difference to the cards that s/he has.
The idea is to float over the opponent’s flop bet to take control over the pot and put the continuation bettor on the back foot.
