How does the sizing of a 3-Bet differ from that of an open raise?

The sizing of a 3-Bet is typically larger than that of an open raise, as it increases the cost for the opponent to call and isolates them. The standard size is 3-4 times the open, but it is affected by position and stack depth. For example, from the blinds against a button open, a 3-Bet can be set to 3.5 times the open; while in position, it can be 2.5-3 times. When deep-stacked, a larger size can be used; when short-stacked, the size is reduced or even all-in.

What hands should I use to 3-Bet bluff?

There are typically two types of hands for 3-Bet bluffing: one is blockers, such as A2s-A5s, which block opponents' AA and AK, and have flush potential; the other is medium playability hands, like suited connectors (67s, 78s) or small pairs (55-77). These have some post-flop hand strength, giving a chance even if called. Avoid bluffing with complete garbage, as it's hard to continue after being called. In terms of frequency, the suggested ratio of value to bluff is about 2:1 to 1:1, adjusted based on opponent's fold rate.

What should I do when facing a 4-Bet?

When facing a 4-Bet, your decision depends on hand strength and stack depth. Generally, the value hands from your initial 3-Bet (like AA, KK, AK) should continue by 5-Bet shoving or calling; most of your bluffing hands should fold. However, when deep-stacked (e.g., 200BB+), you can occasionally call the 4-Bet with some strong hands to slow play a trap. When short-stacked (<50BB), only continue with very strong hands, because after a 4-Bet the pot is large and your options are limited. If you often fold your 3-Bet bluffs, opponents may frequently 4-Bet to exploit you, so you need to occasionally call or 5-Bet bluff to balance.

How wide should a 3-Bet range be to be reasonable?

There is no fixed answer for the 3-Bet range; it depends on position, opponent, and game dynamics. From tight to loose, ranges are roughly: a very tight player out of position might only use JJ+, AK (about 3% of hands); an average player on the button against a loose cutoff might use 12%-15% of hands (including value and bluffs). A common suggestion is: when in position, the range can be widened to 8%-12%; when out of position, it should be tightened to 4%-6%. The most important is to adjust based on opponent's fold rate; if the opponent folds a lot, you can expand the range, otherwise tighten it.

What is a 3-Bet?

In Texas Hold'em, a 3-Bet refers to a re-raise after the first preflop raise. Typically, the first raise entering the pot is called an "open raise," and a raise against that open raise is a "3-Bet." For example, preflop, Player A raises to 3BB, Player B re-raises to 9BB – this action is a 3-Bet. Why “3-Bet”? Because in the betting round: the big blind's forced bet is considered “1-Bet,” the first active raise is “2-Bet,” and the re-raise against it is “3-Bet.”

The 3-Bet is one of the most important aggressive actions preflop. It can immediately narrow an opponent's range, steal dead money in the pot, and establish initiative for later streets. A good 3-Bet strategy is key to balancing value and bluffs.

Purpose and Principles of 3-Betting

The main purposes of 3-betting are threefold:

Value: When you hold strong hands (like AA, KK, AK, etc.), 3-betting builds a larger pot and extracts more value postflop from your opponent's weaker holdings.
Squeeze and Isolate: In multi-way pots, 3-betting forces weak or speculative hands to fold, reduces the number of opponents you face, and lowers the uncertainty of multi-way pots.
Bluff: 3-betting with some medium or backdoor hands forces opponents to fold often, winning uncontested pots. The key to bluff 3-bets is selecting hands with blockers or good postflop playability, such as Axs (suited ace with small kicker), small pairs, or suited connectors.

Position's Impact on 3-Betting

Position is a core factor in 3-bet strategy:

In position (e.g., button, cutoff): You can 3-bet more widely with speculative hands because you have initiative and position postflop. Additionally, opponents need stronger hands to call or 4-bet.
Out of position (e.g., blinds, UTG): 3-bets should be tighter and more value-oriented since you are at a disadvantage postflop and cannot bluff as effectively. For example, when the big blind faces a button open, the 3-bet range should contain more value hands (TT+, AQ+) plus some blockers (A2s-A5s) as bluffs, but at a lower frequency.

Typical 3-bet range example (6-max, 100BB effective stacks):

Button vs CO open: Value: JJ+, AK; Bluffs: ATs, KQo, 67s-89s, A5s, etc.
Big blind vs Button open: Value: TT+, AQ+; Bluffs: A2s-A5s, KTs, QTs, J9s, etc., but at a lower frequency than when in position.

Note: The above ranges are examples only; in actual play, adjust based on opponent tendencies. If an opponent folds frequently, increase bluffs; if they call or 4-bet often, tighten up.

Responding to a 3-Bet

When facing a 3-bet, you typically have four options:

Fold: If your hand is too weak to continue, fold decisively. For example, facing a UTG 3-bet with KJo – unless the opponent is extremely loose, usually fold.
Call: Call with playable hands such as pairs (hoping to flop a set), suited connectors, Ax suited, etc. Position matters: you can call wider when in position.
4-Bet: 4-bet with very strong hands (AA, KK, sometimes AK) or use some medium hands as 4-bet bluffs (e.g., A5s). A 4-bet usually signals a very strong hand or a balanced range.
All-in: With deeper stacks, direct all-ins are rare, but with short stacks (around 30BB or less), going all-in is a common thin-value move.

Common Mistakes with 3-Betting

Overusing 3-bets without adjusting to opponents: Some players discover 3-bets are good and overuse them, only to be frequently 4-bet or called, losing many chips. Adjust 3-bets based on understanding your opponent.
Only 3-betting strong hands, never bluffing: If your range contains only AA, KK, QQ, etc., opponents can easily exploit you by folding because they know you always have a monster. Incorporating appropriate bluff hands makes your range harder to handle.
Ignoring position and stack depth effects: The same hand should be played very differently when 3-betting from the blinds vs. the button, or when facing a UTG open vs. a CO open. Stack depth also changes 3-bet sizing (typically 3-4x the raise with deep stacks, smaller or all-in with short stacks).
Neglecting blocker effects: Blockers refer to the fact that holding a certain card reduces the likelihood of an opponent having a strong hand. For example, when you hold an Ace, the chance of your opponent having AA decreases. When bluff 3-betting, prioritize hands with A or K because they block AK, AA, and KK.

Summary

The 3-bet is a core component of modern preflop poker strategy. Mastering 3-betting requires:

Knowing whether each 3-bet is for value or as a bluff.
Adjusting ranges and frequencies based on position, stack depth, and opponent tendencies.
Balancing your range so opponents cannot easily read your hand.
Making correct decisions when facing a 3-bet by considering hand quality, position, and opponent style.

Remember, 3-betting is not just a raise—it's a systemic attack that must be integrated with 4-betting, calling, folding, and other strategies to form a complete preflop framework.
