When Does a 5-Bet Shove Actually Make Sense?

You reraise before the flop, your opponent raises again, and now the only aggressive move left is all-in. Poker players call those first two reraises a 3-bet and a 4-bet. Most people either never bluff here or remember that ace-five suited is “the solver bluff” and shove it without asking why.

The short answer

Build the shove range from value hands first. Only add bluffs when the opponent can 4-bet and then fold often enough. Good bluff candidates block premium hands and still have some equity when called. If the 4-bettor is never folding, there is no clever bluff to find.

Three useful words

A 5-bet is the third raise before the flop. A blocker is a card in your hand that makes an opponent's strong hand less likely; holding an ace reduces the possible combinations of aces and ace-king. Fold equity is the value you get when a bet makes a better hand fold.

Two quick examples

• Reasonable: In a button-versus-cutoff battle, you 3-bet A♠ 5♠ and face a small 4-bet from an aggressive player. A rare shove can be reasonable because your ace blocks aces and ace-king, and the opponent can fold.
• Not reasonable: You make the same bluff against a tight under-the-gun player whose second reraise means aces or kings. Holding an ace cannot create folds when that player never releases either hand.

Practice this spot first

Try ace-five suited against a cutoff 4-bet. Before you act, answer two questions: which hands call your shove, and does this player really 4-bet hands that can fold?

Start with value hands

Whether a shove is for value depends on what will call it. Against a tight early-position 4-bet, even queens or ace-king may sometimes call and sometimes shove. In a late-position battle, those hands can shove more confidently because the 4-bet range contains more weak hands.

If you cannot name any worse hands that will call, do not automatically label your shove a value bet.

Calculate the bluff requirement

Use the practice hand above. After the cutoff makes it 21 big blinds (21bb), the pot is about 30.5bb and the button must risk 92bb more to shove a 100bb stack. If A♠ 5♠ had no chance when called, the cutoff would need to fold about 75% of the time for the shove to break even. Suited ace-five does have equity against calls, so the real requirement is lower, but the example shows why “I block aces” is not enough. The 4-bet range must contain plenty of folds.

This is why a memorized 100bb chart cannot be carried unchanged into 80bb or 150bb play.

Bluff with hands that are poor calls

Ace-x removes ace-aces and ace-king combinations from the opponent’s range. King-x can remove kings and ace-king. Suited wheel aces add straight and flush equity when called.

Do not shove a hand just because it has a blocker. A good bluff earns more by shoving than it would by calling or folding. If a hand can call profitably and play well after the flop, turning it into a bluff may waste a good option.

Late positions create more possible bluffs

Under-the-gun and hijack ranges start strong, so bluff 5-bets are rare when those positions clash. Cutoff-versus-button and small-blind-versus-big-blind ranges are wider, so a blocker shove is more believable there.

Your opponent matters too. If a player 4-bets only premium hands, drop the theoretical bluff. If someone 4-bets too often and then folds too much to a shove, bluff more often.

Rule of thumb: First name the worse hands that call your value shoves. Then name the better hands your bluff makes fold. If either list is empty, do not invent a 5-bet.

Practice the player, not just the cards

Replay A♠ 5♠ against two cutoff players. Give the first player only aces, kings, and ace-king. Give the second player some suited-ace and offsuit blocker bluffs too. Decide whether to shove against each player before checking the answer. The cards and sizes stay fixed; only the number of hands that can fold changes.

Keep studying

Start the value side with how pocket jacks respond to a preflop reraise, then study when the cutoff should raise a button reraise again. To understand what happens when nobody shoves, review how to play a 4-bet pot with little stack left.
