Poker Squeeze Chart
How often does a preflop squeeze need to work as a pure bluff? This poker squeeze chart lists folds needed and combined MDF for common sizes — 3× through 5× an open — in a live $1/$2 spot with one flat call. Pair it with the 3-bet chart, the 4-bet chart, the fold equity chart, the MDF chart, and the free bluff calculator.
Squeeze sizing chart: folds needed and MDF
Setup used for every row: $1/$2, UTG opens to $6, BTN flats $6, blinds fold. Pot facing the squeezer = $15 (blinds $3 + open $6 + call $6). You have not put chips in yet.
| Squeeze size | % of pot | Folds a pure squeeze needs | Combined MDF |
|---|---|---|---|
| 3× open ($18) | 120% | 54.5% | 45.5% |
| 3.5× open ($21) | 140% | 58.3% | 41.7% |
| 4× open ($24) | 160% | 61.5% | 38.5% |
| 4.5× open ($27) | 180% | 64.3% | 35.7% |
| 5× open ($30) | 200% | 66.7% | 33.3% |
Folds needed = bet ÷ (pot + bet). MDF = pot ÷ (pot + bet). They always add to 100%. Numbers use the same heads-up-style formula as other pages — but a squeeze is multiway: both opener and caller must fold for a pure bluff to win.
The formula
Folds needed = bet ÷ (pot + bet)
MDF = pot ÷ (pot + bet) = 1 − folds needed
Same math as a 3-bet or overbet. A $24 squeeze into $15 puts $24 at risk to win $15, so the pure break-even fold rate is 61.5%. Compare a heads-up 3-bet: only one player must fold. Here two players sit behind the raise.
The multiway trap (why squeezes die as pure bluffs)
Fold rates multiply when everyone must quit:
Both fold = foldopener × foldcaller
If each folds independently about 60%, joint success is only 36% (0.6 × 0.6). A 4× squeeze needs 61.5% on the chart — 36% is nowhere near enough. Light squeezes need a clear fold target or equity when called. Sticky multiway pots: skip the air squeeze.
Worked example: $24 (4×) into a $15 pot
$1/$2. Open $6, flat $6, blinds fold. Pot is $15. You squeeze to $24.
- Folds needed (pure, field formula): 24 ÷ 39 = 61.5%.
- Combined MDF: 15 ÷ 39 = 38.5%.
- Check: 61.5% + 38.5% = 100%.
Against a nitty opener and weak caller who each fold ~70%, joint fold ≈ 49% — still short of 61.5%. Prefer blockers or a hand that plays well when called. Postflop: see the c-bet chart.
Worked example: $18 (3×) — the cheaper light size
Same $15 pot, now a smaller squeeze of $18 (3× the $6 open).
- Folds needed: 18 ÷ 33 = 54.5%.
- Combined MDF: 45.5%.
Dropping from 4× to 3× cuts the pure fold target from 61.5% to 54.5% and risks $6 less when called. That is why many in-position light squeezes favor the smaller end. Out of position, players often size up (4–5×); that raises the bluff fold target again.
When to squeeze small vs large
Smaller (≈3–3.5×). In position, versus opens and calls that fold often enough, or when you want a lower break-even for polar light hands. You lose less when someone sticks.
Larger (≈4–5×). Out of position, versus smaller opens, more than one caller, or with hands that want a big pot (QQ+, AK). Bigger sizes force more folds — but as pure bluffs they need 61–67% folds in this $1/$2 setup, and both players still have to quit.
Skip the light squeeze. Sticky openers, calling stations, or no plan for the flop. Cold-calling multiway changes the math entirely. Stack depth after the squeeze: see the SPR chart.

What is a squeeze play in poker?
A squeeze is a re-raise after an open and at least one flat call. You put pressure on both the opener and the caller at once. Live cash often squeezes to about 3–5× the open, larger out of position or with more callers.
How often does a pure squeeze bluff need to work?
Folds needed = amount you put in ÷ (pot facing you + amount you put in). Facing an open and a call into a $15 pot, a $24 squeeze (4× the $6 open) needs 61.5% folds as a pure bluff; $18 (3×) needs 54.5%; $30 (5×) needs 66.7%. That is the heads-up-style break-even — both players must actually fold.
Why is a squeeze harder than a 3-bet?
You need two folds, not one. The table shows the same bet÷(pot+bet) formula as a heads-up 3-bet, but opener and caller both have to fold for a pure squeeze bluff to win. If each folds independently about 60%, joint success is only about 36% (0.6 × 0.6) — well under the 55–67% targets in this chart.
What is MDF facing a squeeze?
Minimum defense frequency = pot ÷ (pot + bet). Facing a $24 squeeze into $15, combined MDF is 38.5%. Facing $18, MDF is 45.5%. In practice the opener and caller share that continue load; either continuing kills a pure bluff.
When should you squeeze small vs large?
Smaller (≈3–3.5× the open) keeps the fold target lower and loses less when called — useful in position or as a light polar squeeze. Larger (≈4–5×) pressures more of both ranges and builds a bigger pot with premiums, but needs 61%+ folds as a pure bluff and risks more when someone sticks. Versus sticky openers or calling stations, lean value-heavy or skip light squeezes.
