Common Bluff Spots

Patterns that come up over and over at the table

Pre-flop steal (BTN vs blinds)

Strong bluff

You're in position post-flop, only 2 opponents who often fold pre-flop, and you can c-bet most flops. Wide BTN steal range works.

Flop c-bet on Ace-high board (heads-up, in position)

Strong bluff

Pre-flop raiser's range hits Ace-high boards much harder than the caller's. Small c-bet gets folds from most of caller's range.

Turn barrel after flop c-bet (opp checks twice)

Good bluff

Two checks usually mean a weak hand or pure draw. Sizing up to 75% pot puts maximum pressure.

River triple-barrel with blockers

Good bluff (situational)

Holding the Ace of the suit when a flush completes blocks their nuts — they call less often. Pick spots where your story is consistent.

3-bet bluff vs late-position open (suited blockers)

Standard

A5s, A4s have ace blockers that reduce villain's 4-bet range and play well post-flop in single-raised pots when called.

River bet vs calling station

Don't bluff

Stations call with any pair, any draw, often any unpaired ace. Value-bet thin for 60-75% pot with marginal made hands instead.

C-bet into 3 opponents

Don't bluff

Each additional opponent multiplies the chance someone has a hand. Multi-way c-bets need real equity, not pure bluffs.

River bluff with no blockers and inconsistent action

Don't bluff

You're unblocking the value hands you want them to fold, your story doesn't make sense, and you have no fold equity to extract.

The Math Behind Bluffing

Whether a bluff is profitable depends on a simple equation: your bluff needs your opponent to fold more often than the “break-even fold percentage” demands.

The break-even fold % for a bluff is bet ÷ (bet + pot). If you bet $50 into a $100 pot, you need them to fold 50/(50+100) = 33% of the time for the bluff to break even. Any fold percentage above 33% is profit.

This is why smaller bluffs are easier to justify: they require less fold equity. A 33% pot bet only needs ~25% folds to break even. A pot-sized bet needs 50%. A 2× pot overbet needs 67% folds — basically only justifiable when your hand cannot win at showdown and the story is very strong.

The 7 Factors Explained

1. Position

In position you have one more street of information than your opponent. If they check to you, that’s a signal. Bluffs from position succeed because you’re betting after seeing what they do. Out of position bluffs work less often because you’re betting blind to their response.

2. Opponents Left in the Hand

Each additional opponent multiplies the chance someone has a hand worth calling with. A bluff that works 50% against one opponent works ~25% against two and ~12% against three. Bluffs in multi-way pots are almost always -EV.

3. Board Texture and Range Advantage

On an Ace-high flop the pre-flop raiser (you) has many more Aces in their range than the caller does — your perceived range is much stronger than theirs on that board. Conversely, on a 7-5-2 rainbow flop, the caller’s pre-flop calling range includes more middling pairs and connectors than your raise range. Bluff boards that hit your range, not theirs.

4. Your Perceived Range (“Does the Story Make Sense?”)

A consistent story sells. If you raised pre-flop, c-bet flop, barreled turn, and bombed river, the natural interpretation is “they have a strong hand.” If you limped pre-flop, called the flop, checked turn, and now bet huge on the river — your story is “I had nothing and decided to bluff,” which any thinking opponent will see through.

5. Opponent Type

The single biggest factor. Calling stations call no matter what. Bluffing a station is lighting money on fire — value-bet thin for 60-75% pot instead with hands like top pair weak kicker or middle pair. Bluffs work against opponents capable of folding: TAGs, nits, players who recently lost a big pot and may tighten up.

6. Blockers

A blocker is a card in your hand that reduces the combinations of strong hands your opponent can have. Holding the A♠ on a 3-spades board blocks their nut flush, so they call your bluff less often. Bluffing without blockers (or worse, with un-blockers — cards that make their value hands more likely) is dramatically less effective.

7. Stack-to-Pot Ratio (SPR)

If your bet doesn’t threaten further action, it’s a weak bluff. When SPR is low and they call with any pair, you have no leverage. Deep stacks let you size up and threaten future barrels, which gives opponents pause when calling.

Frequency Theory in Two Sentences

GTO theory says your bluffs and value bets should be balanced in proportion to the pot odds you’re offering. Bet half pot → opponent gets 3:1 → your range should be 75% value, 25% bluff so calling vs folding is indifferent for them.

In practice, against exploitable opponents you ignore the GTO balance and play the population read: pure value vs stations, more bluffs vs tight folders. The Bluff Score above hard-codes the most common exploit factors so you don’t have to do all the math at the table.

FAQ

Should I ever bluff a fish?
Almost never. The defining feature of a fish (calling station) is they call too often. If they're going to call with any pair, your bluff has near-zero fold equity — every dollar bet is lost. Save bluffs for opponents capable of folding. Against fish, value-bet thinly and let them pay you off with weak hands.
How often should I be bluffing in general?
Depends on the spot. River bluff frequency is roughly 1 bluff per 2 value bets when betting 50% pot (because of the 33% required fold rate). Bluff frequency goes up at smaller bet sizes and down at larger ones. Across all spots, well-balanced players bluff roughly 20-30% of their betting frequency.
What's the difference between a semi-bluff and a pure bluff?
A semi-bluff is a bet/raise with a hand that can still improve to a winner if called — flush draws and straight draws. A pure bluff has no equity to fall back on (e.g., turn barrel with king-high on a non-coordinated board). Semi-bluffs are more profitable because they have two ways to win: opponent folds, or you make your hand. Most "bluffs" beginners learn are actually semi-bluffs.
Should I bluff more in tournaments or cash games?
Tournaments later — when stacks shrink and ICM pressure kicks in, opponents fold more often to preserve their stack. Cash games typically see less bluffing because there's no ICM and opponents make decisions based purely on hand vs pot odds. Bluff more in tournament late stages, especially near the bubble or pay jumps.
Why does this tool ignore my actual hand?
Because hand strength doesn't determine bluff frequency — situational factors do. A 7-2 offsuit and a queen-high straight draw are both 'bluffs' on the same board against the same opponent. The factors that matter are the spot (position, range, opponent), not the specific cards. That said, blockers (factor 6) is where your hand matters — different cards block different parts of villain's value range.
