You Have 15 Big Blinds. Do You Have to Shove or Fold?
A simple 15bb tournament plan for small raises, open shoves, all-ins over a raise, and the short postflop decisions people forget.
You are down to 15 big blinds and every preflop choice feels like it might be for your tournament life. The good news is that you are not automatically in shove-or-fold land. Small raises still work, especially when you want weaker hands to continue.
The short answer
Use a mix of minimum raises, usually to 2 big blinds (2bb), and open shoves. Move all-in with hands that gain a lot when everyone folds and are hard to play after the flop. Raise smaller with hands that want action or can comfortably respond if a blind shoves. Tighten when players with more chips than you can knock you out near a payout jump.
Three useful words
An open shove is moving all-in when nobody has raised. A shove over a smaller raise is often called a re-jam. ICM, or Independent Chip Model, describes why losing chips can hurt more than winning the same number helps near tournament prizes.
A carry-to-the-table rubric
- Min-raise to about 2bb when your hand wants worse hands to call and you know whether you will call a shove. For example,
A♠ A♦on the button usually prefers 2bb to an open shove. - Open-shove when taking the pot now is a good result and your hand hates raising and then folding. For example,
4♠ 4♦on the button may prefer to shove when both blinds often move all-in over small raises. - Fold when the hand cannot call an all-in and does not gain enough from stealing the blinds.
K♣ 4♦under the gun is still a fold just because the stack is short. - Before acting, check three things: your seat, the stacks behind, and whether a payout jump makes a call tighter.
Practice this spot first
King-seven suited on the button can raise to 2bb or shove, depending on the blinds. Choose one, then use the reads in the practice hand: one blind moves all-in over small raises too often and the other does it too rarely.
What the choices look like
Say you have A♥ Q♥ on the button. Raising to 2bb is reasonable because weaker aces and queens may continue. Shoving 15bb is usually wasteful because it folds out the hands you dominate.
Now say you have 4♠ 4♦ with two aggressive blinds. Shoving can be reasonable because many hands with two cards higher than a four will fold. You also avoid raising small only to face an all-in. Raising to 2bb and then folding every time a blind shoves is the plan to avoid.
When the blinds change the answer
After a 2bb raise, the blinds will often respond by moving all-in. If you open A♣ 9♣ and a tight big blind shoves, raise-folding can be fine. If the big blind shoves far too often, open fewer hands that must fold and call a little wider.
As a defender, decide whether to shove by asking what will fold and how your hand performs when called. The value you gain when the original raiser folds is fold equity. Say the button raises to 2bb and you have A♠ 5♠ in the big blind. A shove may fold out king-queen, small pairs, and weak aces, while your hand still has a chance when called. Against a player who raises only strong hands and rarely folds, the shove loses its main advantage.
What antes and payouts change
Antes add money to the pot and make stealing more valuable. Near a bubble, losing can also hurt more than winning the same number of chips helps. Say nine players remain, eight get paid, you have 15bb, another player has 2bb, and the 35bb chip leader shoves into your big blind. If you cared only about chips won or lost, calling with A♣ 8♣ might be profitable. Once the payout matters, folding can be right because losing would eliminate you before the 2bb stack. Do not copy a chips-only chart into that situation.
One postflop example
You raise to 2bb with K♠ Q♠, the big blind calls, and the flop is Q♦ 7♣ 3♥. With roughly 13bb left and about 5bb in the pot, the stack-to-pot ratio is about 2.6. Top pair is strong enough to bet for value and often continue. If you instead hold A♣ 5♣, betting the flop, turn, and river just because little money remains is not reasonable. A small stack-to-pot ratio does not turn a hand with no pair or draw into a value bet.
Before opening, picture who is most likely to call. Work out the pot and stack you will have on the flop. That keeps you from feeling surprised when your preflop size has already made playing for the whole stack reasonable.
Rule of thumb: At 15bb, choose the preflop action and the postflop commitment plan together.
Practice the one decision that changes
Replay the K♥ 7♥ button hand above at 12bb, 15bb, and 18bb. Predict more shoves at 12bb because raise-folding costs a bigger share of your stack. Predict more min-raises at 18bb because you have room to fold. Then find the first depth where your action changes and write down why.
Keep studying
Compare this boundary with how the strategy changes at 20 big blinds, then see how ICM risk premium reshapes otherwise profitable calls. For the blind-versus-blind version of the same shallow-stack pressure, study when the small blind should limp or raise.
