Float
Calling a bet planning to take the pot away later
Definition
Floating means calling a bet — typically a flop c-bet, usually in position — with a hand of little immediate value, planning to take the pot on a later street as soon as the aggressor slows down. It's not a hopeful call: it's a two-step plan. The right conditions: being in position; holding a minimum of equity (overcards, backdoors, a gutshot) rather than pure air; facing an opponent who c-bets wide but rarely double barrels; on a board where their range often gives up on the turn. The float attacks precisely that "frequent c-bet, frequent give-up" imbalance — one of the most widespread leaks. An out-of-position version exists (check-call the flop, then take the initiative on the turn once they check back — which meets the probe bet), but it's trickier: without position, you won't see their surrender before having to act.
CO opens, you call on the BTN with A♠4♠. Flop J♦8♦2♠, he c-bets a third of the pot: you call — overcard, backdoor flush, backdoor wheel. Turn 3♥, he checks: his range is full of give-ups, and the turn even gave you a gutshot. Your two-thirds bet picks up the pot a large share of the time — and when it doesn't, you still have ways to win.
