What is the difference between 3-Bet and 4-Bet?

A 3-Bet is a re-raise of the first preflop raise (2-Bet), while a 4-Bet is a re-raise of a 3-Bet. Typically, a 3-Bet represents a strong hand or a bluff, while a 4-Bet represents an even stronger hand (like AA, KK) or an extreme bluff. In NLH, after a 4-Bet, it's often close to an all-in, especially when stacks are shallow.

Which hands should I use for 3-bet bluffs?

Ideal 3-bet bluffing hands are those with blockers (like A, K) and some playability, such as A2s, K9s, QJs, medium pairs (like 77-99), etc. These hands can form draws or top pairs postflop if called, and they also block opponent's strong hands (like AK, AA). Avoid using completely disconnected junk hands (like 27o) for 3-betting, because it's difficult to continue if called.

What should the size of a 3-bet be?

Generally, in position, a 3-bet of 2.5-3 times the opponent's raise is sufficient; out of position, a 3-bet of 3.5-4 times is recommended. If stacks are shallow (below 40 BB), you can 3-bet larger or even go all-in. Also, observe opponent's calling tendencies: if they call frequently, increase the size; if they fold often, you can decrease it.

3-Bet: Aggressive Preflop Strategy in Texas Hold'em

Guides11 views

3-Bet is an important aggressive preflop play in Texas Hold'em. This article explains the definition, principles, practical examples, common mistakes and summary of 3-Bet to help players master this key technique.

What is a 3-Bet?

A 3-Bet is a re-raise in Texas Hold'em that occurs preflop, specifically when a player raises after an initial raise (called an "open raise" or "2-Bet"). For example, with blinds of 1/2, the UTG player raises to 6, and the button player re-raises to 18. This raise to 18 is a 3-Bet. The "3" in 3-Bet represents the third betting action (the blinds are the initial bet, the first raise is a 2-Bet, and the second raise is a 3-Bet).

Purpose and Principles of 3-Betting

The main purposes of 3-betting are:

Value Raise: When you hold a strong hand (such as AA, KK, AK, etc.), you 3-bet to build the pot and win more chips postflop.
Isolation: 3-bet a loose opponent to force them to fold, allowing you to play heads-up against a single opponent's weak hand or range, increasing your win rate.
Bluff: 3-bet with medium-strength or weak hands to force opponents to fold and take down the pot immediately.
Control the Initiative: After 3-betting, you usually become the aggressor postflop, making opponents more likely to fold out of respect for your range.

The principle behind 3-betting is based on range advantage and pot odds. When you 3-bet, you signal that your hand is strong. Opponents need a tighter range to call or re-raise (4-bet), otherwise they must fold. Therefore, your 3-bet frequency and range should be dynamically adjusted based on opponent tendencies and position.

Practical Examples of 3-Betting

Example 1: Standard Value 3-Bet

Scenario: 6-handed, blinds 1/2, effective stacks 200. Action: The CO (cutoff) player, a tight-aggressive regular, opens to 6. You hold AA on the button. Analysis: AA is a premium hand. Your goal is to build the pot as much as possible. You 3-bet to 20 (about 3.3x his raise). If the CO calls, you are in position postflop with a strong range advantage. If the CO 4-bets, you can re-raise or shove.

Example 2: Isolation 3-Bet

Scenario: Full ring, blinds 2/5, effective stacks 500. Action: The UTG player, a loose recreational player who often limps, raises to 15. You are in UTG+1 with AJs. Analysis: There are many players behind you. If you just call, you risk being squeezed and cannot easily isolate the opponent's range. You 3-bet to 45 to isolate the UTG player, forcing the players behind to fold and going heads-up with him. Since his range is wide, your AJs has decent equity.

Example 3: Bluff 3-Bet

Scenario: 6-handed, blinds 1/2, effective stacks 200. Action: The button player, who steals blinds frequently, opens to 5. You are in the small blind with A2s. Analysis: The button's range is wide. Your A2s has some playability but is difficult to navigate postflop. You 3-bet to 15, hoping to force him to fold. Even if he calls, your A2s has postflop potential (e.g., flush draws). If you face a 4-bet, you can fold with minimal loss.

Common Misconceptions About 3-Betting

Misconception 1: Fixed 3-Bet Sizing

Many beginners habitually 3-bet to 3x or 3.5x the opponent's raise. In reality, 3-bet sizing should adjust based on position, stack depth, and opponent tendencies. For example, in position you can use a smaller sizing (2.5-3x); out of position, you may need 3.5-4x or even larger. With shallow stacks, your 3-bet should be larger to facilitate a shove postflop.

Misconception 2: Only 3-Bet with Strong Hands

While value 3-betting is important, having too tight a 3-bet range makes you exploitable. Adding some bluff 3-bets (e.g., A2s, K9s, small to medium pairs) helps balance your range, making it harder for opponents to know if you are strong or bluffing. However, be cautious with bluff frequency; too many bluffs invite 4-bet punishment.

Misconception 3: Ignoring Opponent's 4-Bet Tendencies

If you face a player who frequently 4-bets, you should reduce your bluff 3-bets and lean toward calling or value 3-betting with strong hands. Conversely, if an opponent never 4-bets, you can 3-bet with a wider range because his calling range is wider, making your postflop hand equity more realizable.

Misconception 4: Not Adjusting for Position

Position is critical in 3-bet decisions. In position (e.g., button), you can 3-bet with a wider range because you have the positional advantage postflop. Out of position (e.g., small blind), your 3-bet range should be tighter, and your sizing larger to compensate for the positional disadvantage.

Summary

The 3-bet is a powerful weapon in Texas Hold'em. Using it correctly can increase your profits and establish an aggressive image. Key points:

Distinguish between value 3-bets and bluff 3-bets, keeping your range balanced.
Adjust 3-bet sizing based on position, stack depth, and opponent tendencies.
Pay attention to opponents' 4-bet frequency and dynamically adjust your strategy.
Don't be afraid to 3-bet when appropriate, but avoid overusing it.

Through repeated practice and review, you will gradually master the essence of 3-betting and become a tougher opponent at the table.
