4-Bets and 4-Bet Bluffs: How to Use Them Effectively

The 4-bet is one of the strongest and most powerful weapons in poker. It usually represents a very strong range, but experienced players also use 4-bet bluffs to put maximum pressure on their opponents. Knowing when to 4-bet for value and when to turn a hand into a bluff can make a huge difference in your win rate.

What Is a 4-Bet?

A 4-bet happens when a player raises after an open raise, a 3-bet, and then another raise. For example:

Player A opens → Player B 3-bets → Player A 4-bets.

A 4-bet usually means that the pot is becoming very large, and the decision requires careful consideration of ranges, positions, stack sizes, and your opponent's tendencies.

4-Betting for Value

The most obvious reason to 4-bet is to get value from strong hands. Premium hands such as AA, KK, QQ and sometimes AK are common candidates.

However, the correct range depends heavily on the situation. Against a very aggressive opponent who 3-bets frequently, you can confidently 4-bet a wider range. Against a tight player, you should usually respect their 3-betting range more.

The main goal of a value 4-bet is simple: build a bigger pot when you are likely ahead.

What Is a 4-Bet Bluff?

A 4-bet bluff is a raise designed to make your opponent fold a better hand. It is usually used against players who 3-bet too frequently or fold too much to 4-bets.

Good 4-bet bluff candidates often have useful blockers. For example, hands containing an Ace can be attractive because holding an Ace reduces the number of combinations of AA and AK your opponent can have.

Hands such as A5s or A4s can therefore sometimes work well as 4-bet bluffs, depending on the situation and strategy.

When Should You 4-Bet Bluff?

Before making a 4-bet bluff, consider several factors:

• Opponent's 3-bet frequency: The wider they 3-bet, the more opportunities you have.

• Fold-to-4-bet tendency: If your opponent rarely continues against 4-bets, bluffing becomes more attractive.

• Position: Position strongly affects opening and 3-betting ranges.

• Stack sizes: 4-bet bluffs become much more complicated with shallow stacks.

• Blockers: Hands containing an Ace or King can reduce the number of premium hands your opponent can hold.

• Your table image: If you have been playing aggressively, opponents may be more willing to fight back.

Don't Overuse 4-Bet Bluffs

One of the biggest mistakes is trying to 4-bet bluff too often.

A 4-bet creates a huge pot, and if your opponent continues, you can quickly find yourself in a difficult situation. Your bluffs should therefore be selected carefully rather than randomly.

The goal isn't to show your opponent that you can bluff. The goal is to make your entire 4-bet range difficult to exploit.

4-Bets as a Weapon Against Aggressive Players

4-bets can be particularly effective against aggressive regulars. If a player constantly attacks your opens with 3-bets, you can respond by increasing your 4-bet frequency.

This forces them to adjust. They can no longer 3-bet your opens with complete freedom, because they know they may face a large 4-bet.

However, don't turn the battle into an ego contest. The best 4-bets are based on ranges and mathematical logic, not frustration.

Final Thoughts

4-bets are much more than a move reserved for AA or KK. They are an important part of a balanced poker strategy.

Strong value hands allow you to build big pots, while carefully selected 4-bet bluffs prevent opponents from simply folding every time you show aggression.

The key is balance: 4-bet for value when you are strong, choose your bluffs carefully, use blockers intelligently, and always consider your opponent's range before pulling the trigger.

Mastering 4-bets can make your preflop game significantly more aggressive, balanced, and difficult to exploit.
