What is a 3 Bet and 4 Bet in Poker?

A 3-bet and 4-bet are common poker terms that refer to the third and fourth bets made during a betting round. They are integral components of poker strategy, allowing players to build bigger pots with their strongest hands and enabling light 3-bet bluffing. Mastering the art of 3-betting and 4-betting is key to maximizing value and balancing your ranges. This comprehensive guide will explore everything you need to know about utilizing 3-bets and 4-bets effectively in your poker game.

What Does 3-Bet Mean in Poker?

A 3-bet is the third bet made preflop or postflop after a player raises, or 2-bets. It represents the first re-raise in a betting sequence.

For example, Player A opens for a standard raise preflop, then Player B puts in a 3-bet by re-raising. Now if Player A or any other player re-raises again, this would be considered a 4-bet.

The main strategic reasons players 3-bet are:

• For value: With very strong hands like AA, KK, AK. Get more money in the pot when you have a premium hand.

• As a bluff: With weaker hands or suited connectors. Isolate weaker opponents and take down the pot preflop.

• For protection: With medium strength hands. Narrow opponent‘s range so you can realize your equity.

In essence, 3-betting represents considerable strength and narrows the field down to heads-up. It gives you control over the hand by bringing the betting lead over to you.

Making the Distinction Between 3-Bet and 4-Bet

A 4-bet is the fourth bet in a sequence when a 3-bet is re-raised by any player. For instance:

• Player A raises preflop (1-bet)
• Player B re-raises, or 3-bets
• Player A re-raises again, making it a 4-bet

4-betting represents an even stronger range than 3-betting. It is basically the last chance to build the pot preflop, as a 5-bet would likely put one or both players all-in.

Like 3-betting, players may 4-bet for value with premium holdings or as a bluff to win the pot immediately. But hands are generally much stronger overall when 4-betting compared to 3-betting light.

Examples of 3-Bet and 4-Bet Poker Sequences

To help illustrate the difference between a 3-bet and 4-bet sequence, here are two example hands:

3-Bet Example

Preflop: Blinds $100/$200. Player A raises to $600. Player B 3-bets to $1,800.

Here Player B‘s re-raise to $1,800 represents the 3-bet. Any further re-raise by Player A or another opponent would be a 4-bet.

4-Bet Example

Preflop: Blinds $100/$200. Player A raises to $600. Player B 3-bets to $1,800. Player A 4-bets to $4,500.

Player A‘s second re-raise to $4,500 is a 4-bet. Because Player A initiated the betting with a standard open raise, his second re-raise counts as the 4-bet.

How 3-Betting Compares to Other Poker Strategies

3-betting serves a similar purpose as making an isolation raise, or opening raise with the intention of playing heads-up against a specific weaker opponent.

However, 3-betting differs in that you don‘t have to open the action yourself – you can 3-bet against any player‘s open raise. It is reactive rather than proactive like an isolation raise.

Continuation betting is betting the flop after you were the preflop raiser. This is another form of aggression, but it occurs after the flop instead of preflop. 3-betting aims to build a big pot before the flop.

Cold calling contrasts with 3-betting in that you call instead of re-raise. Cold calling is generally done with speculative hands or medium strength holdings rather than premium hands.

So 3-betting represents a more aggressive line than just calling or cold calling a raise. You go on the offensive rather than passively calling.

When Should You Consider 3-Betting?

There are several situations where it can be profitable to put in a 3-bet:

• Against an early position open – 3-betting allows you to play in position postflop against opponents who may have a wide range of hands.

• Against a late position open – Similarly, 3-betting gives you the lead against players who could have many speculative hands.

• Against passive opponents – Re-raise to build a pot against opponents unlikely to 4-bet or fold.

• With speculative hands – Use your 3-betting range to include some suited connectors and small pocket pairs as bluffs.

• With big pocket pairs or AK – Get maximum value with your strongest holdings.

You generally want to 3-bet somewhat selectively to keep your range balanced. Mindlessly 3-betting every open raise will make your hand too easy to read.

Recommended 3-Bet Sizing

A standard 3-bet is usually 2.5-3x the original raise size. For example:

• Opponent raises to $10
• You 3-bet to $25-$30

This allows you to build a decent pot while still leaving room for your opponent to call or 4-bet.

Against particularly passive opponents, you can sometimes size your 3-bet slightly smaller to entice calls. But don‘t reduce your sizing too much or you look weak and risk giving your opponent good pot odds.

Effective 3-Bet Hand Ranges by Position

Your 3-betting hand range should vary based on your position relative to the preflop raiser. Here are some approximate guidelines for good value 3-betting ranges by position:

UTG Position: 22+, AJs+, AQo+

HJ Position: 22+, ATs+, KQs+

CO Position: 22+, A9s+, AJo+, KQo+

BTN Position: 22+, A5s+, A9o+, KJo+

SB Position: 22+, A2s+, A5o+, KTo+

And you can include some suited connectors, small pairs, and suited aces as 3-bet bluffs, concentrating them in late position.

For example, from the button you might add hands like 76s, 65s, 54s, T9s, 98s, A4s-A2s as bluffs. Just don‘t overdo it.

4-Betting Strategy Tips

• Focus your 4-bet range on AA, KK, AK – your strongest holdings.

• Size your 4-bet around 3x the 3-bet. Make it big enough to force tough decisions.

• 4-bet bluff selectively and sparingly against aggressive opponents. Hands like AQs or JJ can work.

• Be prepared to fold to a 5-bet all-in unless you have a hand you‘re willing to get stacks in with. Assume a 5-bet is the nuts.

• Don‘t forget to balance your 4-betting range with hands like QQ, JJ, TT as "protection" hands. You can‘t only 4-bet monsters.

• Against nitty players, expand your value 4-betting range. But keep it tighter against LAGs who can 5-bet light.

How to Play Against a 3-Bet

When facing a 3-bet, you generally have three options:

4-bet – Re-raise again with your strongest holdings like QQ+. Also good to balance with some 4-bet bluffs.

Call – Flat call with speculative hands that flop well like suited connectors and small pocket pairs. Implies some strength.

Fold – Dump marginal hands with too much reverse implied odds. Protect your stack.

4-betting is best with your premiums as it builds a big pot preflop and seizes the betting lead. Calling keeps your range wide and realizes your equity. Folding protects your stack from getting stacked should you miss the flop.

Making the Most of Your 3-Betting Range

Follow these tips to maximize your 3-betting strategy:

• 3-bet in position with a polarized range – strong value hands and well-selected bluffs. Avoid marginal holdings.

• Size your 3-bets appropriately – not too big or too small. Generally 2.5-3x the open raise.

• Focus your value 3-bets on vulnerable opponents who won‘t fold easily pre.

• Have a plan postflop. Outplay opponents by leveraging your range advantage.

• Be aware of table dynamics. Is a nit 3-betting you? Or a maniac? Adjust accordingly.

• Review your hands to see if your 3-betting range matches your strategy. Don‘t deviate.

• Balance timing – don‘t be predictable and 3-bet the same hands or same type of opponents every time.

Mastering 3-betting and 4-betting can quickly increase your winrate. You force opponents to make tough decisions for their entire stack, earn folds preflop, and build big pots with your strongest holdings. Add these powerful weapons to your arsenal and watch your profits soar.
