What is a 3-Bet in Poker? Types, Examples, Strategies to Win

In the early days of poker, players only used a 3-bet (a re-raise after an initial raise) with their best hands, like pocket aces. However, as poker became more popular, players figured out they could make more money by using the 3-bet more often and with a broader range of hands. Learn when to use this strategy and see some examples.

What is a 3-Bet in Poker?

A 3-bet is the third bet in a poker hand. It happens when a player re-raises after someone has already made a pre-flop raise (called a 2-bet). In Texas Hold ’em and Omaha, the initial blind payments count as the first bet.

A 3-bet is a bold move that shows you have a strong hand. You’ll see it often in online games, tournaments, and cash games. It’s a powerful strategy in Texas Hold ’em. A 3-bet can make other players fold, isolate weaker players & help you build the pot to win more money. Understanding how to use 3-bets is key to winning in poker.

Why You Should 3-Bet More Often

1. Make Opponents’ Decisions Harder: Many players only 3-bet with top hands like QQ or better, or sometimes JJ and AK. This is too cautious. If you only 3-bet with strong hands, your opponents will easily fold weaker hands, and you won’t get value from your best hands. Including a mix of hands in your 3-betting makes it harder for opponents to play against you.
2. Isolate Weak Players: When you 3-bet after a weak player raises, it forces other players who might have played just a single raise. It also puts pressure on the weak player, who might need to handle the situation better. This way, you can often get rid of players who aren’t strong.
3. Reduce the Number of Players in the Pot: The more players in the pot, the less chance you have to win with any given hand. A 3-bet usually makes some players fold before the flop, which means you’re more likely to win the hand.
4. Win the Pot Preflop: Calling a raise doesn’t give you a chance to win the pot before the flop, but a 3-bet can. 

Types of 3-Bet Ranges

Here’s a look at different ways to use a 3-bet:

1. Strong Range: Some players only 3-bet with top hands like pocket kings or aces. This approach needs to be more predictable. If your opponents notice this, they’ll fold when you 3-bet, and you won’t get the most value from your strong hands.
2. Polarized Range: A better approach is a polarized range. This means you 3-bet with both your best hands and some weaker hands, like high pocket pairs or occasional bluffs. Bluffing can help increase your profits, but be careful with weaker hands—use hands that have the potential to make flushes or straights after the flop. Check out tips for better bluffing.
3. Merged Range: This strategy works well against skilled opponents. You 3-bet with a mix of your best hands and some of the next best hands. In other words, you’re only 3-betting with the top 5% of your hands.

Why Poker Players Use 3-Bets

Now that you know what a 3-bet is, let’s consider why poker players use it to boost their chances of winning.

3-Betting for Value

When players have a strong hand, they use a 3-bet to increase the pot and get as much money as possible from their opponents. 

For example, in a $0.5/$1 NL Hold’em game:

• The action folds to the cutoff (CO), who raises to $2.50.
• You’re on the button (BTN) with As Ad (Ace of Spades and Ace of Diamonds).

You have a very strong hand, so you want to raise the bet to $8. This increases the pot from $4 to $12, giving your opponent a chance to raise even more.

3-Betting as a Bluff

Players also use 3-bets as bluffs to mix up their strategy and hide their strong hands. If you are only 3-bet with premium hands, opponents will catch on and fold whenever you 3-bet, which stops you from making the most of your good hands.

To avoid this, players include bluffs in their 3-bet range. A bluff 3-bet means you re-raise your opponent pre-flop with a weaker hand, aiming to win the pot without showing your cards.

For example, in a $0.25/$0.50 NL Hold’em game:

• The CO raises to $1.25.
• You’re on the BTN with As 5s (Ace of Spades and 5 of Spades).

Your hand isn’t strong enough to call or 3-bet for value, so it’s a good candidate for a bluff. The Ace in your hand blocks some of your opponent’s strong hands.

Adding bluffs to your 3-bet range will help you win more pots without contest and keep your opponents guessing. Even if you miss the flop, you can continue being aggressive to win pots later.

Understanding 3-bet bluffing can be complex, but this should give you a basic idea of why it’s an important part of poker strategy. Keep studying to learn more about how to use this tactic effectively.

When to 3-Bet in Poker

3-betting is a great way to build the pot and get more value from your strong hands. Being aggressive can help you win more money if you have a good hand. Beginners might worry that being too aggressive will make everyone fold and they’ll miss out on profits, but this is only sometimes true if you let others join the pot without raising, your hand’s chance of winning decreases. Instead, 3-bet with hands you expect to win to build the pot and increase your profits over time.

Blind Stealing: In poker, some players try to steal blinds by raising with weak hands when they’re in late positions. You can use 3-betting to defend against this. If you’re in the blinds and face a late position raise, you can 3-bet to challenge the player and discourage them from stealing your blinds again in the future.

When to Avoid 3-Betting

Although 3-betting is a powerful move, you should use it wisely because it can sometimes weaken your hand. For example, if you 3-bet with a marginal hand, you might force out weak hands but also face problems from players who only call with stronger hands. 

Only 3-bet if it will:

• Force a weaker hand to call.
• Make a stronger hand fold.
• Get a drawing hand with bad odds to call.

Avoid 3-betting if you don’t think it will achieve one of these outcomes. Consider what you know about the other players and what hands they might have. Based on this information, decide if your 3-bet will lead to a favorable outcome.

How to Play a 3-Bet in Poker

Here’s a simple guide on how to handle a 3-bet:

1. Decide on the Size of Your 3-Bet: Start by figuring out how much to 3-bet. Avoid making very small 3-bets because this gives other players a chance to call with a wider range of hands. Aim for a 3-bet size at least twice the amount of the original raise. Consider making it three times the original raise if you’re in a good position. If you’re out of position, a 3-bet around four times the original raise is better.
2. Adjust Your 3-Bet Range: When you 3-bet from any position other than the blinds, you’ll force players to fold or make them play more carefully. Your 3-bet range should be tighter if you’re in an early position because there’s a higher chance that players behind you have strong hands. The later your position, the wider your 3-bet range can be.
3. Consider the Initial Raiser: Look at where the initial raiser is sitting. If they are in a strong position, consider their likely hand strength before you 3-bet. Keep an eye on how other players are reacting to their raises and adjust your strategy accordingly.

3-Betting Examples

Against a Weak Regular  

200NL 6-Max. $200 Effective Stacks

• Situation: You’re in the big blind with 6♥ 4♥. The cutoff (CO) raises to $5, and two players fold.  
• Opponent: The CO is a weak regular who raises often but folds to 3-bets about 55% of the time.  
• Action: You can 3-bet to around $20. Your hand, 6♥ 4♥, fits well in a polarized range. Even if the CO calls, you’ll still have a decent chance to win with your suited connector.

Against a Loose Opener  

200NL 6-Max. $200 Effective Stacks

• Situation: You’re in the cutoff with A♠ Q♠. UTG raises to $6, and two players fold.  
• Opponent: UTG raises frequently, showing a loose play style.  
• Action: 3-bet with A♠ Q♠. You have three good outcomes:
  • UTG folds, and you win the $9 pot.  
  • UTG calls, and you play in position against a weak range.  
  • UTG 4-bets, and you can call it profitably.  

   Any of these results are favorable with a strong hand like A♠ Q♠.

Against a Late Position Open  

500NL 6-Max. $500 Effective Stacks

• Situation: You’re on the button with J♠ 8♠. The CO raises to $12.50.  
• Action: Your value range includes hands like AJs, JTs, and TT. To balance this, you need some bluffs. J♠ 8♠ is a good bluff candidate. It’s too weak to call but plays well after the flop, making it a suitable choice to 3-bet as a bluff.

Intro to Squeezing

Squeezing is a poker strategy used to take advantage of good pot odds when there’s a raise and one or more calls.

The goal of a squeeze is similar to a standard 3-bet, but you need to make your raise bigger to reduce the chances of the pot getting more players involved.

• If there’s one raise and one call: Raise to about 4 times the original bet.
• If there’s one raise and two calls: Raise to around 5 times the original bet.
• When out of position: Make your raise one bet larger.

These are just general guidelines. Adjust your raise size based on how your opponents play. For example, if you have AA against players who call a lot, you should raise even more.

3-Betting vs. 4-Betting: What’s the Difference?

A 4-bet is when a player raises after someone has already made a 3-bet. Since a 3-bet is a strong move after a pre-flop raise, a 4-bet is even more aggressive and is usually at least double the size of the 3-bet. Betting can continue beyond this, with 5-bets and 6-bets, although rare. Players often go all-in with their entire stack when bets reach this high.

Final Thoughts on 3-Betting in Poker

If you’re new to 3-betting, figure out when to 3-bet for value and 3-bet as a bluff. Many beginners need help distinguishing between these two, but understanding this is key to developing a strong 3-betting strategy.

You should also learn to recognize different 3-betting situations by considering factors like your opponents’ skill, game flow, position, and stack sizes.

Getting good at these aspects will improve your 3-betting game and make you a formidable opponent.
