The c-bet in poker: when to bet the flop, and how much
The continuation bet is the most frequent postflop decision. The real question isn't "did I hit?" but "whose board is this?": textures, sizings, frequencies and common mistakes.
The c-bet (continuation bet) is a flop bet made by the player who raised preflop. It's the postflop decision you'll make more often than any other — and most players make it with the wrong question in mind. The right question isn't "did I hit this flop?" but "whose flop is this?". On boards that favor your range, you can bet small and very often, almost regardless of your cards. On boards that favor your opponent, you check more and bet bigger, with a selected range. Here's how to decide.
What is a c-bet?
You open on the button, the big blind calls, the flop comes, they check: betting here is a c-bet — you "continue" the aggression started preflop. That initiative has real value: you're the one telling a coherent story ("I had a good hand preflop, I still have it"), and your opponent is the one who has to defend.
Why the c-bet prints money
Three engines make it profitable:
Fold equity. An unpaired hand hits a pair or better only about one time in three on the flop. Two-thirds of the time, your opponent has nothing — and a large share of those nothings can't continue against a bet. That fold equity is the c-bet's first source of profit.
Value. With your good hands, the c-bet builds the pot while your opponent still holds hands willing to pay you.
Equity denial. Making two overcards fold when they had 25% to outdraw you shows up on no graph, but it's very real EV.
The real question: whose board is this?
Compare the flop to the two preflop ranges, not to your two cards.
Dry, high board — A♠7♦2♣ after your BTN open against the BB. Your range contains every AK, AQ, AA, 77; theirs would have 3-bet its best aces and almost never arrives strong here. That's perfect range advantage: solvers c-bet this kind of flop at very high frequency, with a small sizing, with nearly the entire range.
Low, connected board — 7♥6♥5♠ in the same spot. This flop smashes the BB's calling range (connectors, small pairs) far more than yours. Your advantage melts; c-betting "out of habit" here is burning chips. You check a lot, and you pick your bets carefully.
The advantage also lives at the top of the ranges: if you alone can hold the board's strongest hands (the nut advantage), you can bet very big — that's overbet territory.
Sizing: two families, not one number
Small and frequent (25-33% of the pot). On dry boards that favor your range. The bet costs little, folds out what should fold, and puts your whole range under protection. Against this sizing, your opponent should defend ~75% of their range per MDF — almost nobody does.
Big and polarized (66-150% of the pot). On dynamic boards or when ranges run closer: you bet your strong hands and best draws, you check the rest. Each bet says more, so it has to win more.
The classic mistake is inverting them: big on dry boards (you only fold out what was already dead), small on wet boards (you gift draws a dream price).

In position or out of position
Position changes everything. In position, you can c-bet wider: if your opponent check-calls, you get to see a free card on the turn whenever you choose. Out of position (you opened UTG, the button called), checking becomes far more frequent — including with good hands, to protect your checking range and set check-raise traps. A player who c-bets 100% OOP and gives up to any raise is an ATM.
Special case: the multiway pot. With three or more players, the probability that someone connected explodes, and fold equity collapses. You bluff-c-bet much less, and your value must be real.
The turn: finish what you started
A called flop c-bet isn't a failure — it's the start of a plan. Good cards to bet again ("double barrel"): those that improve your range more than theirs (an ace or king rolling off after your open), and those that add equity to your hand (backdoor draws turning real). Bad ones: those that complete the obvious draws in their calling range. Barreling at random is expensive; always giving up is too — that's exactly what the BB exploits by floating your c-bets.
The most expensive mistakes
C-betting 100% of flops. Correct fifteen years ago, exploitable today: on bad textures, good opponents check-raise and float without mercy.
One sizing everywhere. Betting "always half pot" ignores the most important information in the hand: the texture. Match the size to the board family.
Ignoring who's across the table. Against a calling station, the bluff c-bet loses its purpose — bet bigger for value, bluff less. Against an over-folder, bluff more. GTO is the baseline; the adjustment is the profit.
Forgetting your own defense. When you're the one calling in the BB, remember the real price of a small c-bet: against 1/3 pot, folding more than 25% of your range makes you exploitable. We covered it in how to defend your big blind.

FAQ
How often should I c-bet? There's no single frequency: on A72 rainbow BTN vs BB, solvers bet almost the entire range small; on 765 two-tone, they mostly check. A good player's overall frequency often lands around 50-70%, but that's a consequence of textures, not a target.
What sizing for a c-bet? 25-33% of the pot on favorable dry boards (high frequency), 66-75% or more on dynamic boards (polarized range). The sizing follows from the texture and the range advantage.
Should I always c-bet top pair? No. In position on a very favorable board, yes, almost always. Out of position or on textures that hit your opponent's range, part of your top pairs check — to call afterwards, protect your checking range and control the pot.
What about multiway? Cut your bluff c-bets drastically: with two or more callers, someone has almost always connected with the flop. Bet your value hands, let your airballs go without regret.
Conclusion
The c-bet isn't a reflex, it's a read: range against range, texture by texture. Small and frequent when the board belongs to you, big and selective when it's contested, patient out of position and disciplined multiway. And like every postflop decision, its quality depends on one thing upstream: knowing precisely which hands make up your preflop range — that's what decides which boards are yours.
