Introduction
A three-bet is one of the most important moves a player can make before the flop. It’s a sign of strength and often shifts control of the hand. To understand poker strategy at a deeper level, you need to know what a three-bet is, why it matters, and how to respond to it.
A three-bet happens when there is an initial raise, and then another player raises again. This is the third bet in the sequence: the first is the big blind, the second is the first raise, and the third is the re-raise. Players use three-bets to apply pressure, build bigger pots, or punish loose openers. It’s a tool used in both cash games and tournaments.
Knowing when to three-bet—and when to fold or call one—is a key part of preflop play. It affects your table image, helps you isolate certain players, and can force tough decisions. Whether you're holding a strong hand or making a move with a weaker one, three-betting gives you options and can shape how the rest of the hand plays out.
In Depth Look
The term refers to the third bet in a sequence: the first is the big blind, the second is the initial raise, and the third is the re-raise—hence, “three-bet.” This action usually signals a strong hand, such as high pocket pairs or premium broadway combinations like Ace-King. But not all three-bets are made with strong hands. Some players use them as bluffs to apply pressure or isolate a specific opponent. Because of this, understanding the context of a three-bet is just as important as knowing the cards behind it.
Three-betting can change the dynamic of a hand. It forces other players to react, often narrowing the field and giving the three-bettor more control. For example, in a full-ring game, if a player in middle position raises and a player on the button three-bets, the original raiser must now decide whether their hand is strong enough to continue. At the same time, the blinds may fold, giving the three-bettor position and initiative. This move also increases the size of the pot, making later streets more valuable—and more dangerous. When used well, three-bets can protect your range, disguise your strong hands, and win pots outright.
However, poor use of the three-bet can lead to trouble. If you three-bet too often without a plan, good players will adjust and punish you. If you only three-bet with strong hands, observant opponents will fold to your raises and you’ll miss value. The key is balance: mixing strong value hands with well-chosen bluffs, and adjusting based on position, stack sizes, and the tendencies of your opponents. Mastering this balance takes experience and discipline, but it’s one of the most effective tools in a serious poker player’s strategy.
Mechanics
They then re-raise to a larger amount before the flop. The size of a three-bet depends on position, stack depth, and game type. In cash games, a common size is 2.5 to 4 times the original raise. In tournaments, with shallower stacks, three-bets are often smaller to manage risk. Position also matters—players tend to three-bet more from late position where they’ll have more information after the flop.
Three-bets serve two main purposes: value and bluff. Value three-bets are made with strong hands to build the pot or punish loose opens. Bluff three-bets target weaker opponents or frequent raisers with hands that are not quite strong enough to call. Successful three-betting depends on understanding your opponent's range, your table image, and how likely it is you’ll get called, folded to, or four-bet.
Key Mechanics to Remember:
- A three-bet is a re-raise made after an initial raise preflop.
- Typical sizing is 2.5x–4x the original raise in cash games.
- Purpose: to extract value from strong hands or to bluff weaker ranges.
Illustrated Example
You’re playing a $1/$2 No-Limit Hold’em cash game, 6-handed. You’re on the button with A♠ K♠. Everyone folds to the player in middle position (MP), who raises to $6. The cutoff folds. It’s your turn. You recognize the MP player as someone who opens a wide range of hands but folds often to aggression.
You decide to three-bet to $18, aiming to either take the pot down now or go heads-up in position with a strong hand. Both the small blind and big blind fold. Action returns to MP, who calls the $18.
The pot is now $39. The flop comes J♦ 7♠ 2♥. MP checks. You have missed the board, but your three-bet range includes overpairs and strong hands. MP knows this. You choose to make a continuation bet of $20, applying pressure. MP folds after a short pause.
Player Perspective
making a three-bet is a decision based on strength, position, and intent. If you're holding a premium hand like A♠ K♠ or Q♦ Q♣, a three-bet lets you build the pot and take control before the flop. You're also applying pressure, especially if the original raiser is known to open with a wide range. In late position, a three-bet can help isolate one player and give you the advantage of acting last. But every three-bet carries risk—you’re committing more chips and inviting bigger pots.
On the other hand, facing a three-bet puts you in a tough spot. You have to judge whether your hand is strong enough to continue, whether the three-bettor is likely strong or bluffing, and how you’ll play postflop if you call. If you're out of position, calling may give up the initiative and force you to play a bigger pot without information. Folding avoids that risk, but too much folding makes you exploitable. Good players know when to stand their ground and when to let go, adjusting their response to the player behind the three-bet, not just the cards in hand.
Conclusion
A three-bet is a key move in poker that shapes how a hand unfolds before the flop. It shows strength, forces decisions, and helps control the pot size. Whether used with premium hands or as a well-timed bluff, the three-bet gives players strategic options to pressure opponents and gain an advantage. Mastering when and how to three-bet improves your overall game and increases your chances of winning pots.
