It's a strategic play where a player calls a bet on one street (usually the flop) with a relatively weak hand, intending to take control of the pot on a later street (such as the turn or river) through aggression. The purpose of floating is to exploit an opponent's perceived weakness, as the initial caller does not yet have a strong hand but believes they can win the pot by bluffing or semi-bluffing later in the hand. Floating requires a good read on opponents and an understanding of their betting patterns. It's a nuanced play that involves calculated risk-taking and strategic thinking.
