To make reading easier and improve your internal SEO, you will find terms such as 3-bet light, 4-bet bluff, pre-flop ranges, blockers, squeeze and cold 4-bet throughout the text. Let's go?
What are 3-bet and 4-bet? Essential concepts
- Open-raise: first pre-flop raise bet (e.g., 2.5x).
- 3-bet: one re-raise about open-raise.
- 4-bet: one re-raise Regarding the 3-bet.
- Squeeze3-bet: A 3-bet is made when there is a raise and one or more calls before you.
- cold 4-bet: A 4-bet made by someone who was not yet involved in the pot (neither the initial aggressor nor the 3-bettor).
Quick tip: 3-bets and 4-bets have two main objectives: value (getting paid off by worse hands) and bluffing (forcing folds and realizing equity). blockers (e.g., Axs) in bluffs increases effectiveness.
Fundamental principles for building strong ranges.
- Position mattersIP (in position) you can 3-bet a little wider; OOP (out of position) prefer stronger ranges and larger sizes.
- Blockers and compositionHands with Ace and King reduce the villain's chance of having premium, great for 4-bet bluffs (A5s-A2s).
- Rake and limitIn micro/low stakes, the rake punishes calls; 3-bet more for value and reduce marginal flats.
- Post-flop plan: think about the SPR (stack-to-pot ratio). Larger 3-bet/4-bet sizes reduce the SPR and simplify decisions.
- GTO x ExploitBalance is key; adjust against those who fold too much (bluff too much) or call too much (value too much).
3-bet ranges by position (a practical and simplified view)
The numbers below are useful approximations for 100bb in a cash game with an open of 2.2-2.5x. Adjust according to the pool and the opponent's style.
| You | Against | 3-bet for value | 3-bet bluff (with blockers) | Observations |
|---|---|---|---|---|
| BTN | CO | JJ+, AK | A5s-A2s, KTs-KQs, AJo-aqo (mix) | IP, can 3-bet 9-12% vs frequent opens |
| SB | BTN | TT+, AQ+ | A5s-A2s, KQo, KJs, QJs (mix) | OOP, use a larger size and a denser value range. |
| BB | BTN | TT+, AQ+ | A5s-A2s, KTs+, QJs, JTs (mix) | Too many calls in the big blind is okay; 3-bet hands that play poorly as calls. |
| BTN | UTG | QQ+, AK | A5s-A4s (low mix), occasional kqs | Vs UTG strong, press bluffs |
| CO | MP | JJ+, AQ+ | A5s-A2s (mix), KQs | Balance between value and blockers |
In squeeze, Increase the frequency of 3-bets for value and choose bluffs with good blockers and playability. Sizes also increase (see below).
Ideal sizes for 3-bet and 4-bet
Cash game (100bb) – practical guidelines
- 3-bet IP vs open 2.2-2.5x: 7.5-9bb (about 3-3.5xo open).
- 3-bet OOP vs open 2.2-2.5x: 9-11bb (3.5-4.5x).
- Adjustment by callers (squeeze): some ~+1bb IP and ~+2bb OOP per caller.
- 4-bet IP: ~2.2-2.4xo size of the 3-bet (e.g., vs 9bb, 4-bet 20-22bb).
- 4-bet OOP: ~2.4-2.7x (e.g. vs 9bb, 22-25bb).
In pools that rarely 4-bet, opt for slightly larger 3-bets for value and reduce marginal bluffs. In aggressive pools, standardize bet sizes and protect your frequency.
MTTs – by stack size
- 40-60bb: 3-bets smaller (2.2-2.5x IP; 2.4-2.7x OOP). 4-bet of ~20-24bb IP and ~22-26bb OOP. Avoid 4-betting/folding with dominated hands.
- 25-40bbincorporate 4-bet shove with AK, QQ (sometimes JJ) vs high 3-bets. 3-bet/fold bluffing with blockers still exists, but sparingly.
- 15-25bb: too much jam or fold. Small 3-bets become predictable; prefer to push with medium pairs and high EV Aces against opponents who 3-bet wide.
- ICM (FT, bubble): tighten bluffs; value needs to be stronger. Avoid marginal OOP spots.
4-bet: when to use it for value and when to bluff
4-bet for value is straightforward: hands like QQ+ and AK Against common 3-bet ranges. Bluffing requires caution:
- Bluffs with blockersA5s-A2s, sometimes K5s-K4s in specific spots. Avoid low-profile connectors without blockers.
- Villain profileIf he has a high "fold to 4-bet", add some bluffs. If he 5-bets/jams too much, reduce bluffs and value hands that can call the all-in.
- position4-bet IP with a higher mix of bluffs; OOP be more selective.
Defending vs 4-bet (100bb, cash)
- 5-bet jamThe default is KK+. In some dynamics, AKs and QQ You can enter (be careful in the micro/low stakes pool).
- 4-bet IP calls: AKs, QQ frequently; JJ-TT mixed; AQs less frequently. OOP, press firmly.
- FoldAKO vs. a very large 4-bet OOP might be a fold. Bluffs without blockers should be called first.
GTO x Exploit: How to Balance Your Frequency
- Base GTOCombine value and bluff in proportions appropriate to the risk/reward (R/R). Standardize sizes so as not to "give away" information.
- Exploit:
- A villain who makes a lot of pre-flop calls: denser value, bluff less.
- Villain who folds too often to 3-bet/4-bet: add bluffs with blockers.
- Aggressive Reg on BTN: 3-bet more than two blinds with Axs and KQs; 4-bet more than IP.
- High rake (micro stakes)Avoid marginal calls out of position; 3-bet for value and simplify post-flop decisions.
Practical examples
Ex. 1 – BTN vs CO (cash 100bb)
CO opens 2.5x, you in BTN with A5s. Great. 3-bet bluff IP (~8.5-9bb). If you take a small 4-bet (~20bb) from a reg who 4-bets too much, some mixes of 5-bet jam They may exist, but the standard is fold A very selective call. Against passive recreational play, less bluffing and more value-betting.
Ex. 2 – SB vs BTN (cash 100bb)
BTN opens 2.2x, you in the SB with JJ. Make 3-bet for value higher OOP (10-11bb). If you receive a 4-bet to 24bb from a tight regular, fold It's okay; vs. aggressive., call It might be feasible.
Ex. 3 – Squeeze BB (raise + call)
UTG opens 2.5x, CO pays, you're in BB with AKo. Squeeze Strong (14-16bb). If UTG 4-bet is small and CO folds, the decision tends to be jam or call IP-dependent; OOP, jam simplifies and achieves equity.
Ex.4 – MTT 30bb (BTN vs CO)
CO opens, you're on the BTN with QQ. 3-bet smaller (~6.5-7bb). If you take a 4-bet of 16-18bb, jam It's a profitable standard. With A5s, prefer fold or 3-bet/fold if there is a large Fold to 3-bet from CO.
Common mistakes that cost you dearly.
- 3-betar “because yes”: all aggression needs a motive (value, bluff with blockers, profitable squeeze).
- Inconsistent sizesVarying the size only "gives away" your hand. Standardize by position and setting.
- Ignore the position3-betting wide out-of-pocket without a post-flop plan is a recipe for difficult spots.
- 4-bet bluff without blockers: tends to burn chips. prefer Axs or Kx with strong blockers.
- Disrespecting ICM In MTTs: Marginal 4-bets in bubbles/final table severely punish your EV.

- What is the position His and mine?
- My size Does the 3-bet/4-bet strategy maintain the SPR plan?
- I have blockersMy hand plays well as a call?
- What is the profile from the villain (fold to 3-bet, 4-bet %, 5-bet jam)?
- There is callers Intermediate (spot squeeze)?
- I am in cash (100bb) or MTT (stack/ICM effects)?
Short FAQ
Should I always include bluffs in my 4-bet range?
Not always. In micro/low stakes, many 5-bet pools bet little and pay a lot; focus on value. In more aggressive games, include bluffs with A5s-A2s.
Can I 3-bet low suited connectors?
Yes, more IP and in squeezes, especially against wide ranges. Out of pocket, be selective.
What is the best hand for a 4-bet bluff?
A5s (and A4s) are classics: they block AA/AK and have decent equity when paid.
Simple model of initial ranges for study.
To begin, use this anchor and adjust it according to the pool:
- Vs UTG: 3-bet for value (QQ+, AK) and minimal bluff (A5s-A4s infrequently).
- Vs CO: value (JJ+, AQ+), moderate bluff (A5s-A2s, KQs), more IP.
- Vs BTN: value (TT+, AQ+), bigger bluff than blinds (Axs, KQs, QJs) with robust OOP sizes.
Train with post-session review: mark it hands In 3-bet/4-bet scenarios, record bet sizes used, results, and the villain's read. The discipline of analysis accelerates your learning curve.
Conclusion: Turn 3-bet and 4-bet into a competitive advantage.
Dominate ranges and sizes The 3-bet and 4-bet system is a game-changer. Understand the impact of position, use blockers intelligently, and adjust accordingly. GTO and exploit According to the opponent's profile. In 100bb cash games, standardize bet sizes (IP 7.5-9bb; OOP 9-11bb; 4-bet ~20-25bb) and use squeeze with more confidence. In MTTs, respect the effective stack and ICM, incorporating 4-bet shoves when profitable.
