To float is calling a flop or turn bet with the intention to bluff later.
Explanation. The term comes from acting passively and then “floating” into position for later leverage—calling early street bets to represent strength on later streets. You aim to take the pot away on turn or river if opponent shows weakness. For example, calling a flop bet on a dry board with plan to barrel the turn when aggressor checks. It’s an advanced strategy tool to balance bluff frequency and induce mistakes.
