How to size your bets when an overcard hits the turn

The reflex is correct. When an overcard lands on the turn after you've c-bet the flop and gotten called, you should generally be betting. Steffen polled the room and the room said "be aggressive" - and that's not wrong. But "be aggressive" leaves out almost everything that matters.

Overcards don't strengthen your range. They reshuffle villain's.

The central idea in this session is that an overcard doesn't just strengthen your range - it reshuffles villain's. After a flop check-call, their range holds a mix of top-pair hands, mid-strength pairs, draws, and weak backdoor holdings. When the overcard arrives, some of those hands jump to the top. Others - the 6x, the 7x, the gutshots that were marginal before - collapse toward air.

Steffen's framework asks one question before you size: where does your range advantage actually live right now?

Dry boards bet big. Wet boards bet small.

A dry overcard on a low rainbow board tends to push the advantage into your top-pair region. That calls for a sizing that builds toward a three-street structure, including overbets at the upper end. A wet overcard - same rank, but now completing a flush draw or bringing straight possibilities - shifts the dynamic. Villain's check-raise frequency climbs. Your necessity to build the pot yourself drops.

Small bets aren't timid - they're a different attack

On a wet overcard, small sizings stop being a fallback and become the primary tool. The flush completion does your pot-building for you through villain's check-raises, so you don't need 175% overbets in the mix anymore.

Five boards, five different answers

Steffen walks through five specific boards with solver data: a J75 rainbow that turns a Q, a J85 with a flush draw that turns the same Q, a T72 rainbow that turns an ace, a T85 two-tone that turns a flush-completing Q, and a 552 board that turns an ace.

That last one is the trap. After a correct flop check-raise from the big blind, villain's calling range on 552 is almost entirely ace-x offsuit - exactly the hands that love the ace on the turn. The solver bets only 22%.

The overcard itself is not always good.

What happens to your river strategy after a small turn bet opens up an uncapped villain range. And the heuristic Steffen uses to pick which slice of villain's redistributed range to attack on every overcard turn.
