What is a 3-Bet

A 3-Bet refers to the third bet preflop, usually occurring after someone opens (a 2-Bet) and you re-raise. It is a key tool for establishing aggression, narrowing opponents' ranges, and gaining pot control. Constructing a proper 3-Bet range requires balancing value hands and bluffs while considering position, stack depth, opponent tendencies, and other factors.

Core Principles of Building a 3-Bet Range

1. Distinguish Value from Bluffs

Value 3-Bet: Use strong hands (e.g., AA, KK, AKs) to raise, expecting to be called by weaker hands or to face a weaker 4-Bet shove. The value range typically has over 50% equity against an opponent's calling range.
Bluff 3-Bet: Use medium-strength or playable hands (e.g., A5s, K9s, suited connectors) to raise, hoping to force a fold, or to steal the pot on the flop if called. Bluff hands often have good blocker effects (blocking strong hands like AA, AK) and backdoor draw potential.

2. Position-Based Adjustments

Position is the most important variable in 3-bet range construction. Generally:

In Position (BTN, CO): You can 3-bet wider because you have a position advantage postflop. A typical range includes about 10-12% of hands.
Out of Position (SB, BB): You should be tighter since you are at a disadvantage postflop. Usually only 3-bet value hands and a few high-quality bluffs, around 6-8% of hands.
Versus Blind Positions: If an opponent opens loosely from CO or BTN, you can 3-bet wider from SB or BB, but proceed with caution.

3. Adjustments Based on Opponent Type

Against Tight-Passive Players: Reduce bluffs because they fold often, but when they call, they usually have strong hands. Primarily 3-bet for value.
Against Loose-Aggressive Players: Increase bluffs and re-bluffs because they may frequently 4-bet. You need to balance your range to avoid being exploited.
Against Calling Stations: Only 3-bet for value and reduce bluffs, as they rarely fold.

Example: Standard 100BB 3-Bet Range

Here is a typical 6-max strategy assuming an opponent opens from MP with about 20% of hands, and we are on the BTN:

Value 3-Bets (about 3.5%):

AA, KK, QQ, JJ (drop JJ against tight opponents)
AKs, AKo (sometimes used as bluff/value hybrids)
AQs (possibly as thin value)

Bluff 3-Bets (about 4-5%):

A5s, A4s (block AK, AA)
K9s+, Q9s+ (suited with some connectivity)
87s, 76s (suited connectors with postflop potential)
Some offsuit hands like AJo, KQo (depending on opponent)

Total range about 7.5-8.5%, roughly 10% of hands. Out of position, narrow it to about 5-6% and reduce low-quality bluffs.

Strategy Against 4-Bets

When your 3-bet gets 4-bet, you need a defense strategy:

Continue with AA, KK, AKs, QQ (sometimes) by 5-bet shoving (or calling, depending on position and stacks).
Call the 4-bet with medium-strength value hands (e.g., JJ, TT, AKo) and play cautiously postflop.
Most bluff hands (e.g., A5s, 87s) should fold, unless they have sufficient equity and implied odds.
Overall, your defense frequency against 4-bets should be about 40-50% of your 3-bet range, keeping enough strong hands.

3-Bet Sizing Adjustments

Standard size: In position, 3x the open (e.g., MP opens 3BB, you 3-bet to 9BB).
Out of position, use a slightly larger size (3.5-4x) to compensate for positional disadvantage.
Against short stacks, you can use a smaller size to induce a shove.
Avoid over-betting your 3-bets, as opponents can easily exploit it.

Practical Considerations

Note stack depth: With deep stacks (>100BB), you can increase bluff frequency because there is more room to maneuver postflop. With short stacks (<40BB), primarily 3-bet for value.
Avoid frequent 3-bets against calling stations, as they won't fold.
Against skilled players, randomize your 3-bet range to avoid being exploited.
Track opponents' fold-to-3-bet rate. If it's high, increase bluffs; if low, reduce them.

Summary

Building a 3-bet range is an art that requires balancing value and bluffs, dynamically adjusting based on position, opponent, and stack depth. Beginners can start tight and gradually incorporate bluffs. Continuously review and refine your range through practice. Remember: 3-betting is not an end in itself, but a tool for profitability.

Applicable Scenarios

Cash Games — How to construct 3-bet ranges in deep-stacked 6-max open/3-bet/postflop pot-control lines.
MTT — Frequency changes in open/3-bet/jam under ante and blind structures.
Bubble Phase — ICM increases fold equity, tightening marginal spots.
Final Table — Payout jumps alter the marginality of call/jam decisions related to 3-bet ranges.

Common Mistakes

Common Mistake 1: Over-calling 3-bets in the "how to construct 3" scenario, ignoring positional disadvantage.
Common Mistake 2: Using the same bet size on all streets, easy to [exploit].
Common Mistake 3: Playing key tournament stages as if deep-stacked cash games, ignoring [ICM].

Frequently Asked Questions (FAQ)

Q: Should I raise or [limp] preflop when constructing a 3?
A: In [6-max], the standard is to [open raise]; [limp] requires a clear exploitative reason.

Q: How should I proceed facing a 3-bet?
A: Choose between 4-bet, [call], or [fold] based on effective stack, position, and opponent type.

Q: How do I determine if [bluff catch] is appropriate?
