Poker 3-Bet Defense: GTO Calling Ranges When You Face a Re-Raise in 2026
You open the pot. Someone re-raises you. Now what? Most players call too wide out of position, only 4-bet with premiums, and bleed chips in 3-bet pots. This guide covers the exact hands to call, fold, and 4-bet from every position — and how GTO frequencies actually look when you face a 3-bet.
Quick Answer
When facing a 3-bet, GTO strategy folds roughly 55-65% of your opening range, calls about 25-30%, and 4-bets the rest. In position you call more and fold less. Out of position you tighten up, fold more, and use 4-bets or folds rather than flat calls. The biggest mistake most players make: calling too wide from bad positions, especially the small blind and early position seats.
Your three options when facing a 3-bet
Every time someone 3-bets you, you have the same three choices. The mistake most players make is treating “call” as the default and only thinking about folding or 4-betting in obvious spots.
Fold
More often than you think. Most of your opening range cannot profitably continue vs. a legitimate 3-bet. The pot odds are bad, the stack-to-pot ratio gets squeezed, and many hands that play well as an opener become marginal or losing calls in 3-bet pots.
Example hands: KJo, QJo, lower suited connectors from OOP, weak aces (A2o-A8o), offsuit broadways that are dominated
Call (flat)
Best when you have position, your hand plays well postflop, and the 3-bettor is not so tight that you're always dominated. Calling in position lets you realize equity without committing more preflop. Avoid flatting in position-neutral or out-of-position spots unless your hand is very strong.
Example hands: JJ, TT, 99, KQs, QJs, JTs, AJs, ATs, 98s, 87s (in position); 4-bet or fold these OOP
4-bet
With premium hands for value, and with select bluff hands for balance. A 4-bet either wins immediately or builds a massive pot when called by a worse hand. Your 4-bet range needs both value hands and bluffs to be unexploitable.
Example hands: Value: AA, KK, QQ, AK. Bluffs: A5s, A4s, A3s, A2s (blocker hands that can barrel postflop)

GTO calling ranges vs. a 3-bet, by position
Position changes your defense range more than anything else. From the button you can call a wide range and realize equity comfortably. From UTG you’re nearly forced to 4-bet or fold because flatting a 3-bet from early position puts you out of position for three streets against a player representing a strong range.
| Your position | Call vs. 3-bet | 4-bet | Fold |
|---|---|---|---|
| BTN (best defense) | 30-35% | 12-15% | 50-55% |
| CO | 22-28% | 10-13% | 59-68% |
| HJ / LJ | 18-22% | 9-12% | 66-73% |
| UTG / UTG+1 | 10-15% | 8-11% | 74-82% |
| SB (worst defense) | 10-15% | 12-16% | 69-78% |

Button defense: the easiest spot to get right
The button is where you should be defending the widest. You have position on everyone for the rest of the hand, your equity realization is highest, and even marginal hands can generate profit when you see flops in position against a 3-bettor.
Against a CO or SB 3-bet from the button, your calling range should include:
Call in position
- JJ, TT, 99 (too strong to fold, too thin to 4-bet for value)
- AQo, AJs, ATs (strong but not premium enough to 4-bet/fold)
- KQs, QJs, JTs (suited broadways play well in 3-bet pots)
- 98s, 87s, 76s (suited connectors with good implied odds)
- KJs, KTs (semi-strong, position-dependent)
Fold from BTN
- KJo, QJo, KTo (offsuit dominated hands)
- Small pocket pairs (22-66) against tight 3-bettors
- Low suited connectors (54s, 43s) without good implied odds
- Weak offsuit aces (A2o-A8o)
Against a tight 3-bettor who only 3-bets top 5%, tighten your calling range significantly. Against a wide 3-bettor (12%+ of hands), you can call or 4-bet lighter. Adjusting to the 3-bettor’s range is where the real edge lives in these spots.
Out-of-position 3-bet defense: the hard spots
When you open from UTG, HJ, or LJ and get 3-bet by a player who acts after you, you’re in trouble. You’ll be out of position for the entire hand, which means your equity realization drops dramatically. Hands that are solid in-position calls become marginal or losing OOP.
The GTO adjustment is clear: fold more, call less, and let your 4-bet range do the heavy lifting when you want to continue. From UTG facing a 3-bet, you should be folding roughly 75-80% of your opening range. That sounds extreme. It’s correct.
UTG vs. BTN 3-bet: what to do
The small blind is the worst position to defend a 3-bet from. You’re out of position against the entire table, and even hands like AQs become tricky calls. In the SB facing a BTN 3-bet, GTO leans heavily toward 4-bet or fold rather than calling. Many players lose significant chips here by flatting hands they should either ship in or release.

Building your 4-bet range: value and bluffs
A 4-bet range that only contains AA and KK is exploitable. Smart 3-bettors will notice you always have a monster when you 4-bet and will fold, or adjust by 5-betting light and getting stacks in when they have the equity edge.
GTO 4-bet ranges are polarized: strong value hands at the top, bluff hands that have fold equity and some equity when called. The hands that belong in your calling range (JJ, TT, AQo) are explicitly excluded from most 4-bet ranges.
4-bet for value
- AA, KK — always 4-bet, never call
- QQ — 4-bet or call depending on position; 4-bet is safer OOP
- AK (both) — 4-bet from most positions, especially OOP
- AKs — sometimes call IP vs. wide 3-bettors
4-bet bluffs
- A5s, A4s, A3s, A2s — block AK/AQ, can barrel postflop
- KJs (sometimes) — blocks KQ that might call; position-dependent
- Avoid bluffing with hands that play well as calls (JTs, 98s)
- Avoid bluffing with hands that have no blocker value (72o)
Why suited aces work as 4-bet bluffs: A5s blocks AK and AQ, the hands most likely to call your 4-bet. When your bluff gets called, you still have a flush draw and nut blocker, giving you legitimate postflop outs. Hands like 98s are too strong as calls to burn as a bluff.
For sizing: in position, 4-bet to 2.2-2.5x the 3-bet. Out of position, 2.5-3x. Consistent sizing regardless of hand strength is essential. See the full breakdown in our poker 4-bet strategy guide.
Big blind defense vs. squeeze plays
The big blind is a unique spot: you’re already invested in the pot, you have a stronger incentive to continue, but you’re also the worst position at the table. When a player squeezes (3-bets after a raise and call), your defense range narrows significantly because the pot odds shift with two players in.
From the BB facing a standard 3-bet (not a squeeze), you get to close the action, which means your defense frequencies increase slightly. But “close the action” is not a license to call wide. You’re still OOP for three streets. Many players over-defend from the BB citing pot odds, then bleed chips for the rest of the hand because they picked up poor implied odds with marginal hands in 3-bet pots.

How stack depth changes your 3-bet defense
At 100bb, there’s room for calling ranges and postflop play. As stacks shrink, the 3-bet/4-bet game simplifies fast.
| Stack depth | Defense adjustment |
|---|---|
| 100bb (standard) | Full calling and 4-bet ranges apply. Call with suited connectors, speculative hands IP. 4-bet polarized range with bluffs. |
| 60-80bb | Calling ranges tighten slightly. 4-bet commits more of your stack, so 4-bet range shifts toward value-heavy. JJ becomes a cleaner 4-bet/fold rather than call. |
| 40-50bb (tournament middle stage) | Thin calls disappear. Suited connectors and speculative hands are near-folds. 4-bets often become shoves. Defense simplifies to 4-bet/fold or fold. |
| 20-30bb (short stack) | Call or fold with most hands. Any 4-bet is all-in. Defense range: shove with TT+, AK, AQs. Fold everything else vs. a tight 3-bettor. |

The 4 most expensive 3-bet defense mistakes
Calling out of position with hands that need position
KQs, AJs, and JTs play great in position in 3-bet pots. Out of position, they become losing calls. If you’re opening UTG and getting 3-bet by the BTN, those hands need to be folded or 4-bet depending on your range construction. Stop making reflex calls.
4-betting only AA and KK
A 4-bet range without bluffs is exploitable. Any competent player will fold everything but the nuts when you 4-bet, and continue to 3-bet you relentlessly. Include A5s, A4s, and similar hands in your 4-bet range to balance your value 4-bets.
Defending too wide against tight 3-bettors
Against a player who only 3-bets the top 5% of hands (QQ+, AK), your calling range collapses dramatically. JJ might be a fold. AQo definitely is. Adjust your defense based on who is 3-betting, not just the position. Playing GTO against someone exploiting you is leaving money on the table.
Ignoring the 3-bettor’s position
A 3-bet from the BTN and a 3-bet from the BB are not the same. The BB 3-bet is polarized (either very strong or a bluff). The BTN 3-bet can include a wider linear range. Defend slightly tighter against BTN (who has position postflop) and wider against BB 3-bets where the solver shows more bluffs.
Hand example: CO opens, BTN 3-bets, what now?
Setup: $2/$5 cash, 6-max, 100bb effective. You open CO to 3bb with J♥T♥. BTN 3-bets to 9bb. Blinds fold. Action to you.
Call. JTs is a strong semi-speculative hand with position. Against a BTN 3-bet range (which includes value and bluffs), JTs has enough equity and playability to call profitably. The pot odds are reasonable at ~2.5:1 to call 6 more into a 15bb pot.
Don’t 4-bet. JTs is not a 4-bet bluff candidate here. You’d be burning equity to bluff with a hand that plays well as a call. Save 4-bet bluffs for hands with blocker value (suited aces) that don’t play as well as flat calls.
Same hand, different position: You open UTG with J♥T♥. BTN 3-bets to 9bb. Blinds fold.
Fold. You’re out of position for the entire hand. JTs relies on position and implied odds to work. Without position in a 3-bet pot, the hand loses most of its value. Fold is the correct play from UTG vs. a BTN 3-bet.
How to practice 3-bet defense with Preflop Wizard
3-bet defense is one of the highest-variance areas of preflop play: the spots come up constantly, the ranges are position-dependent, and the mistakes compound quickly. Reading about the correct ranges helps. Drilling them until they’re automatic is what actually changes your results.
Preflop Wizard quizzes you on the exact spots: you see your position, the open size, the 3-bet size, and your hand. You pick the action. The app tells you whether you were right, what the GTO frequency was, and which hands belong in each category. You can filter to practice only 3-bet defense spots until the position-based adjustments become second nature.
For building your overall preflop framework, start with our opening ranges by position guide to understand what range you’re defending from, then work through 3-bet strategy to understand the attacker’s side of these pots.
Stop leaking chips in 3-bet pots. Preflop Wizard builds correct defense habits through repetition, not memorization.
FAQ
What hands should I always fold when facing a 3-bet?
Offsuit hands that are easily dominated: KJo, QJo, KTo, QTo, and weak aces (A2o-A8o) from all positions. Low suited connectors (54s, 43s) and small pocket pairs (22-55) are near-folds in most spots, especially out of position. These hands struggle to realize equity in 3-bet pots where stacks go in more frequently.
Should I always 3-bet with AA and KK, or is slow-playing sometimes right?
Always 4-bet AA and KK when you face a 3-bet. You are not slow-playing here — you’re re-raising a player who has already represented strength. Calling with AA against a 3-bet gives away information (you would have 4-bet most of your range) and loses value from building the pot. Slow-playing is a postflop concept, not preflop strategy.
How often should I fold to a 3-bet?
At GTO frequencies, roughly 55-65% of your opening range is folded to a typical 3-bet. The exact number depends on your position and the 3-bettor’s range. If you’re opening 20% of hands from the BTN and someone 3-bets, you’re defending about 35-40% of those hands (8% of all hands). If you open 12% from the CO, you defend roughly 28-32% of those (3.5-4% of all hands).
Is it ever right to call a 3-bet out of position?
Rarely, and with a narrow range. From UTG facing a 3-bet, even AQo is often a fold. The hands that can call OOP are strong enough that many players 4-bet them anyway: AA, KK (4-bet), QQ (sometimes call or 4-bet), JJ/TT (narrow calls that realize equity through raw strength rather than playability). Most of your calling range disappears when position is gone.
What is the difference between 3-bet defense and big blind defense?
Standard 3-bet defense is when you’ve raised first and someone re-raises you. Big blind defense is when someone else opens and you defend from the BB (calling or re-raising). The strategies overlap conceptually but the hands and frequencies differ significantly. Defending from the BB against an open involves a wider range because you have already invested and are getting better odds. Defending after you’ve opened (3-bet defense) requires tighter calling ranges since you have more at stake and often worse position.
