What it measures
Fold to c-bet measures the receiving end of the c-bet. A player called a raise before the flop, the raiser bet the flop, and now the player has to answer: fold, call or raise. FCB is how often they fold.
It covers players on both sides of the raiser. If the big blind checks, the raiser bets and the big blind folds, that’s a fold to c-bet. If a button caller folds to the cutoff’s c-bet, that counts too. The turn and river versions ask the same question one street later, against the double and triple barrel.
Don’t confuse it with these neighbors:
- Fold vs bet counts the first bet a player faces on a street from anyone, at any size. FCB only counts the raiser’s c-bet.
- Check-fold counts any check followed by a fold to anyone’s bet. FCB needs the bet to be a c-bet, and also counts players who never checked because they sat behind the raiser.
- Fold to stab is the reverse spot: the raiser checks, someone bets, and the raiser folds.
The other two answers are call c-bet and raise c-bet. All three share the same chances, so together they come to roughly 100%.
How it’s calculated
The rule, per street:
- Chance: the player’s first action after the c-bet, facing exactly the c-bet. If someone raised in between, it isn’t a chance, because the question changed.
- Event: they folded. Calls count toward call c-bet, raises toward raise c-bet.
- Streets: on the flop, the preflop raiser’s c-bet; on the turn, the double barrel; on the river, the triple barrel.
- Excluded: streets where fewer than two players could still bet, limped pots (no c-bet exists), and streets where someone donk-bet before the raiser acted (the raiser’s bet is then not a c-bet).
Formula: folds ÷ c-bets faced with no raise in front.
In multiway pots, a player who faces the c-bet after someone else called still counts, since they face the same single bet. Each street is kept in narrower versions: in or out of position against the c-bettor, by pot type (single-raised, 3-bet, 4-bet or more) and heads-up or multiway. Position here is measured against the c-bettor alone, unlike the c-bet stat, which uses last to act among everyone.
Example: Rosa faced 30 flop c-bets with no raise in front. She folded 18, called 10 and raised 2. Her fold to c-bet is 18 / 30 = 60%, call c-bet 10 / 30 = 33% and raise c-bet 2 / 30 = 7%. After her 10 calls, the raiser bet the turn 7 times and she folded 2: fold to double barrel 2 / 7 = 29%, shown faded at 7 chances.
Why it matters
Fold to c-bet sets how much your c-bet bluffs earn. Compare their number with what your size needs to break even as a pure bluff:
| C-bet size | Bluff needs folds |
|---|---|
| 20% pot | 16.7% |
| 33% pot | 24.8% |
| 66% pot | 39.8% |
| 100% pot | 50% |
| 133% pot | 57.1% |
Against a player who folds 60%, every size up to 133% pot shows a profit, if their fold rate holds at that size. That “if” matters: FCB averages every size they faced, and most players fold more to bigger bets. Check the size-specific stats such as fold vs small bets before you choose.
Multiway, fold equity shrinks fast. If two players each fold 55%, both fold only 0.55 × 0.55 = 30% of the time; with three it’s 17%. A 33% c-bet needs 24.8%, so it still works against two such players but not three. That’s why the HUD keeps a separate multiway version.
The number changes your value bets too. A player who rarely folds is paying you off with weak pairs and draws, so bet thinner and bigger when you have it.
Too low, about right, too high
The flop, turn and river versions share the same typical range, 38–60%.
Too low: under 38%
What it says
The player keeps going with most hands: any pair, any draw, often overcards or a backdoor draw. Check whether it’s calls or raises. A low FCB with a high call c-bet is a calling station; Station, Fish and Whale types often look like this on PokerNow. A low FCB with a high raise c-bet is an aggressive player who fights for pots, which is a different problem.
Either way, your c-bet bluffs aren’t getting through.
How to exploit it
Value-bet and cut bluffs.
- Stop c-betting air on the flop, especially hands with no pair and no draw. Check them and take the free card or give up.
- Bet your value thinner: top pair with a weak kicker and good second pairs can c-bet for value, and plan to bet the turn as well.
- Size up with strong hands, to 66–75% pot, as long as their fold rate stays low at the bigger sizes.
- Bluff only with real equity (flush draws, open-enders), so you still win when called.
- If their non-folds are mostly raises, see raise c-bet instead: c-bet a stronger range and call their raises lighter.
About right: 38–60%
What it says
The player defends a reasonable share of flops. Most decent players sit here, and it says less than it seems, because it blends in and out of position, heads-up and multiway, and every bet size. Solid players fold more out of position and multiway, and less in 3-bet pots, where their range is stronger and the pot is already big compared with the stacks.
How to exploit it
Find the leak in the details.
- Check the version on the badge. A player at 50% overall may fold 65% out of position and 35% in position.
- Look at the fold rates under each size button on the panel. Many fold about as often to 33% as to 66%, which makes the small bet the better bluff.
- Compare flop and turn. A 45% flop number with a 62% turn number means they call the flop light and fold the turn: double barrel more.
- Pair it with check-raise. A middling FCB with a high check-raise means many of their non-folds are raises, so c-bet hands that can stand one.
Too high: over 60%
What it says
The player folds whenever they miss, which on most flops is most of the time. That’s fit-or-fold: they continue with top pair, sets and strong draws and let everything else go. Tight players (Nit and Rock types) and cautious players out of position land here. In home games it’s often someone who calls preflop hoping to hit big, then gives up when they don’t.
When they do continue, they usually have something.
How to exploit it
C-bet more, and size down.
- Heads-up, c-bet close to your whole range at 25–33% pot. At 33% a bluff needs folds only 24.8% of the time, far below what they give.
- Use the smallest size that still folds them out. If their fold rate under the 20% or 33% button is close to their rate at 66%, take the cheap price.
- Respect their calls. When they call a small c-bet, slow down with air on the turn unless their fold to double barrel is high too.
- Check their check-raise first. High FCB with a low check-raise is the easy case. High FCB with a high check-raise means they fold their misses but fight back with draws and sets, so keep checking some medium hands that hate a raise.
On the flop, turn and river
Flop: fold to c-bet
On the flop the caller still holds their whole preflop calling range, and most of it misses, so this is where fold equity is largest. What moves the number:
- Position. Big blind defenders face c-bets out of position with a wide range and usually fold more than in-position callers, who can float and realize their equity.
- Pot type. In 3-bet pots the caller’s range is stronger and the pot is big compared with the stacks, so folds drop.
- Players. Multiway, each player folds more, since someone else often has it.
- Board. Ace-high and king-high boards draw more folds than low connected ones, where the caller’s suited connectors and small pairs connect.
Flop exploit: the big blind is often the table’s biggest overfolder, because it defends the widest. If a player’s out-of-position version is over 60%, c-bet them small with every hand heads-up and give up when called unless you improve.
Turn: fold to double barrel
Fold to double barrel (FCB-T) answers a different question: they called the flop, so what did they call with? Their range is now pairs, draws and floats. Players who float the flop with ace-high or backdoor draws give up a lot here; players who only call flops with pairs fold less.
The range is the same 38–60%, but the pattern across streets tells you more than either number. A low flop FCB with a high turn FCB is the classic “call once, fold later” player: barrel the turn, especially on cards that don’t complete draws. A high flop FCB with a low turn FCB means their flop calls are strong; once they call, give up your bluffs and bet the turn only for value.
The pot is bigger now, so each turn bluff risks more. After a called 66% flop bet, the pot is 2.32 times as big, and a 66% turn bet costs 2.32 times what your flop bet did.
River: fold to triple barrel
Fold to triple barrel (FCB-R) is a bluff-catching stat. The caller has called two bets, so their range is mostly one pair plus draws that missed. The missed draws fold no matter what, so what this number really shows is how often they let go of a pair.
Compare it with the math for your size. A pot-size river bluff needs folds 50% of the time, and a 75% bet needs 42.9%. A player folding over 60% to triple barrels gives your missed draws an easy bluff. A player under 38% calls down with most pairs: don’t bluff them on the river, and bet your top pairs for value. Check went to showdown to confirm the picture.
Be careful with the sample. Few hands reach a third c-bet, so FCB-R stays faded for a long time, and 60% over 10 chances is ±15 points: it could easily be 45% or 75%. Lean on the turn number until the river one fills in.
When it’s your own number
On your own badge, the reads show what others can do with your number. Fold too much and they’ll c-bet you more, and smaller. Fold too little and they’ll value-bet you and cut their bluffs.
To check yours, use the minimum defense frequency as a rough guide. Against a 33% c-bet, MDF is 75.2%: fold more than about a quarter of your range heads-up and any pure bluff profits. Against a 66% bet it’s 60.2%. If you fold 65% to small c-bets, keep more backdoor draws, overcards in position and weak pairs. If you fold under 38% across the board, especially multiway or against big bets, let go of bottom pairs and gutshots on wet boards. Then check the turn version: many players defend the flop and fold too much on the turn.
Using it on the HUD
The badge shows fold to c-bet for players in and out of position to the player with the lead, both before the c-bet (so you can plan yours) and after it. On your turn, when your bet would be a c-bet, the panel shows each player’s fold to c-bet alongside the fold rates under your size buttons.
Gold means over 60%, blue under 38%. When the exact spot has fewer than 12 chances, the HUD steps back to a broader version, dropping heads-up or multiway first, then pot type, then position; the tooltip names the version, and a number still under 12 chances is faded. A read like “Overfolds to c-bets: c-bet more, size down.” appears only with 12 or more chances and at least one standard error outside the range.
Sample size: over 30 chances a 50% number is ±9 points, and over 100 it’s ±5. The typical range is 22 points wide, so 30 chances will show you an extreme player and 100 will place a normal one. Read it with check-raise and raise c-bet.
Questions
What is a good fold to c-bet percentage?
Between 38% and 60% is normal. Lower is right in position and in 3-bet pots; higher is reasonable out of position and in multiway pots. Over 60% heads-up usually means overfolding: against a 33% c-bet, the minimum defense frequency is 75.2%, so folding more than about a quarter of your range lets any bluff profit.
What does fold to c-bet mean in poker?
Fold to c-bet is how often a player folds when the preflop raiser bets into them on the flop, with nobody raising first. It counts players who checked and then folded as well as players who folded in position behind the raiser. The HUD keeps turn and river versions for the second and third barrels.
How do you exploit a high fold to c-bet?
C-bet more often and smaller. Against a player folding over 60%, a 33% bet only needs to work 24.8% of the time, so betting your whole range heads-up shows a profit if their fold rate holds at that size. Slow down when they call, and check their check-raise first: some high folders fight back hard with the hands they keep.
Fold to c-bet vs fold vs bet: what’s the difference?
Fold to c-bet only counts bets from the preflop raiser, or on later streets from the player who kept c-betting. Fold vs bet counts the first bet a player faces on a street from anyone, at any size. A player can fold to c-bets often but call donk bets and stabs, so use the stat that matches the spot.
Why don’t fold, call and raise c-bet add up to exactly 100%?
They share the same chances, but raise c-bet only counts the times the player had chips left to raise. When a c-bet puts them all-in, the chance counts for fold and call but not raise, which nudges the total slightly above 100%.
