At a $1/$2 table, a player opens to $6 and another raises to $20. The $20 is a 3-bet even though it is 10 big blinds, not three big blinds. If someone then re-raises the $20 to $50, that is a 4-bet. None of these labels alone says the wager was profitable or that the player holds a premium pair.
Count the Actions, Not the Chips
Start with a six-seat no-limit Hold'em hand. The small blind posts $1 and the big blind $2. Three seats fold to the button, who raises to $6. The small blind folds. The big blind re-raises to $20. This is a preflop 3-bet because it raises an open raise over the live big blind.
| Step | Player's action | Total live wager for that player | Sequence label |
|---|---|---|---|
| 1 | Big blind posts | $2 | First live bet preflop |
| 2 | Button open-raises | $6 | Raise, often called the 2-bet |
| 3 | Big blind re-raises | $20 | Re-raise, the 3-bet |
| 4, if made | Button 4-bets | $50 | Re-raise again, the 4-bet |
The small blind's $1 remains in the pot after folding, but it does not become a separate bet in this counting convention. Nor does a call advance the number. If another player called the button's $6 before the big blind re-raised, the big blind's action would still be a 3-bet. In that multiway situation it is also commonly called a squeeze, as the PokerStars squeeze lesson explains.
“Raise to” and “Raise by” Are Different Numbers
In the example, the button raises to $6, which means $6 total invested preflop, not $6 on top of the $2 blind. The big blind already has $2 posted. To 3-bet to $20, that player adds $18, reaching a total live wager of $20. The size of the increment over the $6 open is $14; it is not the same as the $18 extra chips the big blind physically pushes out.
If the button calls, the button adds $14 to the $6 already invested, bringing that player's total to $20. At that moment the pot is button $20 + big blind $20 + folded small blind $1 = $41. It is not $43: the original big blind is part of its player's $20, not another $2 to add. This simple accounting is more useful than memorizing a “3×” slogan.
For a minimum legal re-raise, the size of the preceding raise increment matters. In this hypothetical no-limit hand, opening from a $2 big blind to $6 raises by $4; the big blind's raise from $6 to $20 raises by $14. A full next re-raise would have to go to at least $34 ($20 + $14), barring an all-in exception or house-specific rule. PokerStars' rules explainer states that a no-limit raise must at least match the previous bet or raise; check the actual room's rules for short all-ins and reopening action.
One Action Ledger, Two Effective Stacks
Now give the button and big blind the same starting stack in two versions of the hand: $200 each (100 big blinds) or $80 each (40 big blinds). The button holds K♦J♦ and the big blind A♠Q♠ in both versions; the cards are fixed solely to keep the scenarios comparable, not to declare either action optimal. The other four seats fold, the small blind's $1 stays in, the button opens to $6, the big blind 3-bets to $20, and the button calls. No ante, straddle or rake is included. Both stacks cover the action.
| Item after the button calls | 100-BB case | 40-BB case |
|---|---|---|
| Starting stack per active player | $200 | $80 |
| Invested preflop per active player | $20 | $20 |
| Remaining effective stack | $180 | $60 |
| Pot including folded SB's $1 | $41 | $41 |
| Remaining-stack-to-pot ratio (SPR) | 180 ÷ 41 ≈ 4.39 | 60 ÷ 41 ≈ 1.46 |
The action label and pot are identical, but the remaining stack relative to the pot differs sharply. A $20 3-bet commits 10% of a $200 stack and 25% of an $80 stack. That fact does not tell you which hands to 3-bet or call. It tells you why a preflop chart that ignores effective stacks cannot be copied into both games unchanged. The $41 pot is before any flop bet and before rake. See our poker positions guide for why the button and blinds will also have different postflop information.
Why Players 3-Bet: Value, Folds and Initiative
A player may 3-bet expecting worse hands to continue, hoping an opener will fold, or using a strategy that mixes these purposes. A hand is not intrinsically a “value 3-bet” in every opponent and position matchup. It is a value action only relative to the hands the opponent is likely to continue with and the price paid. PokerStars' lesson describes both value and bluffing motives; neither is a guarantee that the next particular 3-bet makes money.
Consider the difference between an opener who almost never folds and one who often abandons a late-position steal. The same re-raise can face radically different continuing ranges. The number of players left to act also matters: a re-raise from the small blind against an early-position opener is not the same spot as a big-blind re-raise against a button open. If a caller is trapped between opener and re-raiser, the pot and incentives change again. None of those differences is encoded in the phrase “3-bet to $20.”
Initiative means being the last aggressor, not owning the right to win the next street. If the 3-bet is called, the re-raiser can still miss the flop, face a strong board for the caller's range, or act out of position. Avoid advice that says to continuation-bet every 3-bet pot automatically.
Linear and Polarized Are Range Shapes, Not Magic Hand Lists
A linear 3-betting range selects candidates from the strongest hands down to a boundary, without a deliberate gap within that 3-bet range. A polarized one has strong 3-bets and selected weaker bluffs, with some middling hands possibly called instead. PokerStars' dedicated range-shape lesson explains those structures. It does not supply a universal range for every rake, stack, format and opponent.
| Question before drawing a range | Why it changes the chart |
|---|---|
| Who opened, and from which position? | A likely early-position range may differ from a button opening range. |
| Who 3-bets, and who remains behind? | Position and additional players change the risk of a call or further raise. |
| What are the effective stacks? | The same dollar amount commits a different fraction of the shorter stack. |
| Is this cash or tournament play? | Rake, antes and payouts can alter the decision context. |
| Does this opponent call or fold to re-raises? | A value label depends on what worse hands continue, while a bluff needs a credible fold path. |
This table is a checklist, not a color-coded 13×13 recommendation. To build a reproducible range, a researcher must declare the game, positions, effective stack, rake or payout assumptions, sizing and opponent model, then validate every cell. Until then, listing “always 3-bet hand X” would turn a useful concept into unsupported advice. A starting-hands chart for an unopened pot would not answer this facing-raise decision either.
What Changes When You Are in or Out of Position?
The big blind in our example will usually act before the button after the flop if both continue. That makes the spot different from a player on the button 3-betting an early-position open and then having position. Bigger out-of-position sizing is one common teaching heuristic, but the PokerStars 3-bet lesson's suggested multipliers are examples of a strategy, not tournament rules or a promise of expected value.
Record a sizing as a total and state the original open. “3-bet to $20 over $6” is unambiguous; “3-bet three times” could mean three times the open, three times the blind or an extra three times an existing wager. In the $1/$2 example, $20 over $6 is about 3.33 times the open and 10 times the big blind. Neither multiple defines the term 3-bet. A squeeze against an opener and caller may need a different analysis again, because an additional player's chips and range are in the pot.
Facing a 3-Bet: Call, Fold or 4-Bet
The opener must now compare the extra call price, its range, the re-raiser's likely range, effective stacks and position. In the worked hand, the button has $6 invested and must add $14 to call the $20 total. Folding forfeits the already invested $6, but does not require adding the $14. Calling creates the $41 preflop pot described above. A legal 4-bet would commit a larger total and can prompt another response; the label is merely the next step in the sequence.
Do not call simply because “I already put $6 in.” Those chips are already in the pot. Do not 4-bet automatically because the opener has a visually attractive hand. A call can be valuable if a hand realizes equity well in position; a fold can be correct if the continuing range and price are unfavorable. PokerStars' facing-3-bets lesson explicitly cautions against following charts blindly. A real answer needs a specific opponent and game model, not a blanket rule disguised as a chart.
Multiway Pots and Squeezes
Suppose the cutoff opens to $6, the button calls $6 and the big blind raises to $24. The big blind's wager is still a 3-bet, because the intervening call is not a raise. With the small blind's $1 folded, the pot before the cutoff or button responds is CO $6 + BTN $6 + BB $24 + SB $1 = $37. The big blind added $22 over its posted $2. If both opponents fold, the big blind wins the existing pot; if one calls, the pot grows further. The word squeeze refers to the raise-plus-caller configuration, not a fourth wager.
This second scenario is separate from the $20 heads-up example. Its $24 size is simply an illustrative legal raise-to amount; it is not a claim that 4× the open is best. There are two opponents whose responses matter. A range that works when the button alone opens may not apply after the cutoff opens and the button calls.
Can You 3-Bet After the Flop?
Yes. The count restarts on each betting street. Suppose the flop checks to a player who bets $10; an opponent raises to $30; the original bettor re-raises to $70. That final $70 action is the flop's third wager, a 3-bet. The preflop big blind is irrelevant to the flop count. Calling the $30 does not create a 3-bet; only another raise does. All stated amounts assume sufficient stacks and a legal no-limit raise.
Because preflop 3-bets are discussed so often, some writers use “3-bet pot” to mean a hand re-raised before the flop. The term does not prohibit re-raises on later streets. When documenting a hand, say preflop 3-bet or flop 3-bet and write the actual raise-to amounts. That is clearer than assuming every reader has the same street in mind.
A Five-Point Error Check
Before using a chart or recounting a hand, check: (1) which street are we on; (2) what was the live bet before the first raise; (3) which actions were calls versus raises; (4) does each figure mean to or by; and (5) what fraction of the effective stack does the raise commit? Our $1/$2 example answers all five: preflop, $2 big blind, button raises to $6, big blind re-raises to $20, and the same $20 has a different stack impact at $200 versus $80.
The clearest takeaway is mechanical: a 3-bet is a re-raise. Whether to make one is a separate strategic decision that requires positions, ranges, stack depths and the opponent's likely response. Keep those two questions separate and both the terminology and the hand review become much easier to audit.
