What is a 5-Bet in Poker?

A 5-bet is the fifth raise in a betting round, typically occurring preflop. The sequence is: open-raise, 3-bet, 4-bet, 5-bet. In most cash games with 100 big blinds (bb) effective stacks, a 5-bet is an all-in shove. It is not a bluff; it is a value raise with a premium hand, usually AA or KK, sometimes QQ or AKs depending on the situation.

What a 5-Bet Is and Is Not

A 5-bet is a raise that ends the preflop action. It is the last raise you can make before the flop, because after a 5-bet, the only remaining action is call or fold (unless stacks are deep enough for a 6-bet, which is extremely rare).

A 5-bet is not a bluff. Unlike a 3-bet or 4-bet, which can be used as bluffs or semi-bluffs, a 5-bet is almost always for value. When you 5-bet, you are saying, "I have a hand that can beat my opponent's 4-betting range." You are not trying to make them fold; you are trying to get called by worse hands.

A 5-bet is not a call. It is a raise. If you have a hand like QQ and your opponent 4-bets, you might call to see a flop, but that is not a 5-bet. A 5-bet is a raise, and it is usually all-in.

How to Use a 5-Bet

The size of a 5-bet depends on the effective stack size. In typical 100bb cash games, a 5-bet is an all-in shove. This is because the pot is already large after the 4-bet, and a raise to anything less than all-in would commit you to the pot anyway. For example, if you open to 3bb, your opponent 3-bets to 10bb, you 4-bet to 25bb, and your opponent 5-bets, the pot is already over 50bb. A raise to 60bb would leave you with only 40bb behind, and you would be getting almost 3-to-1 on a call if they shoved. So you might as well shove yourself.

In deeper stack games (200bb+), a 5-bet might not be all-in. You could 5-bet to a size that is not all-in, but this is rare and requires careful planning. In most cases, even at 200bb, a 5-bet is a shove because the pot is already bloated.

Here is a table showing typical 5-bet sizes by effective stack:

Who 5-Bets and Who Doesn't

A 5-bet is a rare move. It only happens when there is a 4-bet, which itself is rare. The player who 5-bets is usually the original raiser, because they have the strongest range. The player who 4-bets is usually the 3-bettor, and they are often polarized: they either have a premium hand or a bluff. When you 5-bet, you are targeting the value part of their range.

This raise in the sequence

Example 1: Take the 5-Bet Shove

You are in a 6-max cash game with 100bb effective stacks. You open to 3bb from the button with A♠A♥. The small blind 3-bets to 12bb. You 4-bet to 30bb. The small blind 5-bet shoves all-in for 100bb. You call. This is a clear 5-bet spot. Your AA is the best hand almost always. You are not worried about the 5-bet; you are happy to get all-in. This is the classic value 5-bet.

Example 2: Don't 5-Bet with a Bluff

You are in the same game, but you have A♠5♠. You open to 3bb from the button. The small blind 3-bets to 12bb. You 4-bet to 30bb as a bluff, hoping to make them fold. The small blind 5-bet shoves all-in. You must fold. You cannot 5-bet bluff here because a 5-bet is all-in, and A5s is not strong enough to call a shove. You made a mistake by 4-betting a hand that cannot stand a 5-bet. The 5-bet is a signal that your opponent has a premium hand, and you should let it go.

When Not to Use a 5-Bet

Do not 5-bet when you have a hand that is not strong enough to call an all-in. If you 4-bet with a bluff like A5s, and your opponent 5-bets, you must fold. You should not 5-bet with hands like JJ or TT, because they are often dominated by QQ, KK, or AA. You should not 5-bet with AKs if you think your opponent's 4-bet range is only AA and KK, because you are a big underdog. In general, only 5-bet with hands that have at least 50% equity against your opponent's 5-bet calling range.

Also, do not 5-bet if you are out of position and your opponent is a tight player who only 4-bets with AA/KK. In that case, you should just call their 4-bet with a hand like QQ, or fold if you have a weaker hand.

The Next Decision After a 5-Bet

If you make a 5-bet and your opponent calls, you are all-in (or nearly all-in) and the hand is decided. You will see the flop, turn, and river, and the best hand wins. There is no further decision for you unless you are not all-in (deep stacks). If you are not all-in, you must be prepared to continue on the flop. For example, if you 5-bet to 80bb at 200bb stacks and your opponent calls, the pot is 160bb and you have 120bb behind. You should be committed to the pot, so you will likely shove any flop.

If you face a 5-bet, your decision is simple: call or fold. You should call with hands that have enough equity against your opponent's 5-bet range. Typically, that means AA and KK. Sometimes QQ and AKs are calls, depending on the opponent. You should fold everything else. For example, if you 4-bet with A5s and face a 5-bet, you fold. If you 4-bet with QQ and face a 5-bet, you might call if you think your opponent could be 5-betting with AK or QQ, but you might fold if they are super tight.

Leaks on this raise

• 5-bet bluffing: Trying to 5-bet as a bluff is a mistake. A 5-bet is all-in, and you are risking your entire stack to win a pot that is already large. The only time a 5-bet bluff could work is if your opponent folds too much to 5-bets, but that is rare and requires a very specific read. In general, do not 5-bet bluff.
• 5-betting too wide: Some players 5-bet with hands like JJ or AQ, thinking they are strong. But these hands are not strong enough to call a 5-bet shove, and they are often dominated. Stick to AA, KK, and sometimes QQ or AKs.
• Calling a 5-bet with a bluff 4-bet: If you 4-bet bluff and face a 5-bet, you must fold. Many players make the mistake of calling because they feel committed. But you are not committed; you are beat. Fold and save your chips.
• Not considering stack sizes: A 5-bet is usually all-in, but if you are deep, you might not be all-in. If you 5-bet to a non-all-in size, you must be prepared to continue on the flop. Many players 5-bet to a size that leaves them with an awkward stack, making postflop play difficult. In most cases, just shove.
