You have 20 big blinds, the tournament is one elimination from the money, and the chip leader raises again.
Your hand is good enough to shove in any normal spot, but should you still do that on a tournament bubble?
That gap between normal poker and bubble play is where a lot of money changes hands. Some players lock up and blind away a healthy stack while others play as if there are no payouts attached and punt their stack one spot short.
Good poker bubble strategy sits between those two mistakes, and this guide gives you a great starting point for playing big, medium, and short stacks.
What Is the Bubble in a Poker Tournament?
The money bubble is the point where the next player out gets nothing, and everyone who remains gets paid. If 100 players cash and 101 are left, you’re on the stone bubble.
In practice, I treat the bubble as any point where you could reasonably fold your way into the money most of the time.
Measure the Distance as a Share of the Field
“Two off the money” means very different things in different tournaments. With 102 players left and 100 getting paid, only about 2% of the field has to bust, and that will happen in a few hands. With 10 players left and 8 getting paid, a fifth of the field has to go, and that can take a long time.
So count the players who must bust as a share of the players left. The bigger the field, the closer you really are, and the more it pays to wait.
Once the field gets close enough, most tournaments go hand-for-hand, with every table playing one hand at a time so nobody can stall past the bubble.
Big Stack Bubble Strategy
The bubble is the most profitable time to be aggressive, and the big stack gets to do it. The players you cover can’t call you light, so you win far more pots than your cards deserve.
Raise More, but Raise Small
A common mistake is open-shoving every hand because nobody can call. That works until another big stack wakes up with aces or kings, and suddenly you’ve gone from table captain to being in bad shape.
Small raises do the same job with far less risk. A minimum raise forces the blinds to decide whether to put chips at risk, and most of the time they simply fold. Hands with an ace or a king are the best ones to add, because they make it less likely that someone behind you has a hand strong enough to shove.
The exception is when it folds to you in the small blind against a shorter big blind who is trying to outlast even shorter stacks. There you can shove extremely wide.
Bet Small and Often After the Flop
When a covered player calls, use small, frequent continuation bets. Each small bet nudges more of their stack into the pot and sets up a river where calling means risking their tournament.
They know it too, which is why they fold so often. Winning a string of four and five big blind pots for an hour can take an average stack to double average without a single showdown.
Respect It When Someone Fights Back
When a player who has been folding suddenly shoves on you, believe them. Their range is much stronger than it would be in a normal spot. A hand like ace-ten offsuit that would call a 14 big blind shove on any other day can simply be folded.
Only Bully the Players Who Care
Bubble pressure only works on players who feel it. Some opponents will blind off a huge stack to lock up a cash. Others don’t care about the money at all, and if you keep bluffing into them, you’ll lose a big pot at the worst possible time.
Find the players who are folding and attack them. Play close to normal against the ones who aren’t.
Avoid the Other Big Stacks
Big stack against big stack is the most expensive collision on the table. Each of you is risking the best seat in the tournament. Call more, 3-bet less, and let the other big stack force it.
Medium Stack Bubble Strategy
The medium stack is the hardest stack to play on the bubble. You have too much to gamble with and not enough to bully anyone who covers you.
Stay Away From Stacks That Cover You
Every time you call off your stack and lose, you hand a pay jump to every short stack that was about to bust before you. So against a bigger stack, fold hands you’d normally be happy to get all in with. Medium pairs and hands like ace-jack and king-queen are the usual casualties.
Act Like the Big Stack When You Can
You still need chips. Apply small bits of pressure to the players you cover and to other medium stacks, because losing two or three big blinds to them doesn’t hurt much and winning them several times in a row adds up fast.
Two situations make you the big stack for one hand. The first is when the real big stack has already folded and everyone left to act is shorter than you. The second is when the chip leader is sitting tight and waiting for the money. If the leader won’t use the stack, you can.
Play Small Pots After the Flop
When a bigger stack is in the pot, check more, call more, and raise less. A hand like top pair or an open-ended straight draw can bet in a normal spot. If you bet and get raised near the bubble, you end up putting in a large chunk of your stack with a hand that doesn’t want to play for everything.
Skip thin value bets on the river for the same reason. I cover the postflop side in more detail in common ICM mistakes.
Don’t Freeze
Tight isn’t the same as frozen. With 30 big blinds, you can’t fold a hand like king-eight offsuit in the big blind to a minimum raise from a loose big stack. You’re getting a great price, and you can play a small pot.
Short Stack Bubble Strategy
With a short stack, start by being honest about your goal. You’re probably not winning the tournament from here, and a lot of your equity comes from cashing.
Know Where You Stand in the Field
Being short doesn’t automatically mean being in danger. With eight big blinds and four stacks sitting on two big blinds each, you should basically never go broke before they do. With seven big blinds when the next shortest stacks have 10 and 15, you almost always need to double up.
So look around, and in a big field take a walk past the other tables. If you’re the one most likely to bust next, play your normal push/fold charts. If several players are shorter, tighten up and let them go first.
Shove, Don’t Call
With fewer than about 12 big blinds, go all in with the hands you play. Your best weapon is fold equity, and you have more of it on the bubble than at almost any other time.
The best targets are loose raises from a big stack who is opening too many hands. A hand with an ace is ideal for shoving over those raises. Be much more careful when a medium stack raises into bigger stacks, because that player needs a real hand to do it.
With ace-king, kings, queens, jacks, or ace-queen, get your chips in. You aren’t guaranteed another good hand before the blinds reach you.
Fold Big Hands With a Micro-Stack
There is one exception, and it comes up more often than you’d think. Say you have under four big blinds in a large field, you’re very close to the money, and several other players are just as short or shorter.
Doubling from four big blinds to eight barely changes your chance of winning the tournament. Cashing is where your money is. In that spot, folding hands as strong as pocket tens or ace-king can be right, because someone else is very likely to bust first.
If nobody else is short, this doesn’t apply. Then you have to play.
Watch the Clock
Try not to let the blinds go up while you’re in the big blind. With a tiny stack, paying a bigger blind and ante one hand earlier than necessary can cost you a whole orbit. Sometimes that means acting quickly to get through the blinds before the level ends.
Taking your time is also within the rules before hand-for-hand play begins, and every hand you aren’t dealt is a hand someone else might bust in. Just stay within reason.

When to Tighten Up and When to Take a Risk
Tightening up too early is as costly as not tightening at all. If you start folding with a third of the field left, you bleed chips for hours and arrive at the real bubble short.
Don’t Adjust Too Soon
As a rough guide, take an event that pays about 15% of the field. With around 30% of the field remaining, make small adjustments at most and keep playing solid middle stage tournament strategy. The main change is avoiding big stack against big stack collisions.
Once only a handful of players need to bust, the correct adjustments get extreme. At one EPT Monte Carlo, an absent player had been blinded down to a single big blind. At another table, two players got 40 big blinds each all in preflop with queens against ace-king. One of them bubbled and the absent player cashed.
The size of the minimum cash matters too. When it’s worth more than two buy-ins instead of the usual one and a half or so, everyone should be tighter, and a big stack is worth even more.
The Risk Worth Taking Before the Bubble
Here is the part most players miss. Being the big stack on the bubble is one of the most profitable spots in the whole tournament. So with something like a quarter of the field left, a close gamble that would make you that big stack can be worth taking, even though it costs you some cashes.
I remember a $10,000 event with about 60 players left and 50 getting paid. I took a risk, won a flip, and had around 80 big blinds. The bubble lasted about four hours, everyone at my table had a medium stack and needed to cash, and I got to raise nearly every hand. I finished the bubble with around 150 big blinds.
That only works under two conditions:
- Your opponents care about cashing. If the table is full of players who don’t mind bubbling, a big stack buys you nothing, so pass on the gamble.
- You can’t already play like the big stack. If the chip leader at your table is passive and letting you run the table, taking extra risk to become the leader is a mistake.
On the stone bubble itself, with a stack that is nearly certain to cash, the same gamble is a punt.
How Much Tighter Should You Call an All-In?
Now the math, and only as much as you need.
In a cash game, a chip you win is worth exactly as much as a chip you lose. In a tournament, the chips you lose are worth more than the chips you win. Busting ends your chance at every future payout, while doubling up doesn’t double your prize equity. That idea is the heart of ICM, the model that converts stacks into money.
Why a Coin Flip Loses Money
Four players remain with identical stacks, and each stack is worth $575 in prize equity. Two of them get all in on a perfect coin flip.
The winner’s stack is now worth $800. The loser takes fourth place for $200. On average each of them ends up with $500, so both gave away $75, and that $150 went to the two players who folded.
Folding isn’t neutral on the bubble. Every time someone else busts, your stack gains value without you risking anything.
Risk Premium in Rough Numbers
Risk premium is the extra equity you need on top of your pot odds before calling for your stack makes money. Our guide to risk premium in poker tournaments uses a simple example. If pot odds say you need 40% equity, a risk premium near an important payout might push that to 48 to 50%.
How big the premium is depends on your stack and on the stack you’re facing. This is the rough guidance I teach. Treat it as a sense of scale and not as exact figures, because the real number moves with the payouts, the stacks, and how many players are about to bust.
| Your stack | Facing a big stack | Facing a medium stack | Facing a short stack |
|---|---|---|---|
| Big | very large, roughly 18 to 35% | small | close to none |
| Medium | large, roughly 10 to 20% | large, roughly 10 to 20% | small |
| Short | moderate, roughly 9 to 15% | about the same | about the same |
Two things move you inside those ranges. More players on the verge of busting pushes every number up. Being the only short stack pulls yours down, because you’re the one most likely to go broke next anyway.
The premium also changes through the tournament. In one calculation from our coaches, with equal stacks in an event paying about 12% of the field, it was only about 3% with 40% of the field left, about 5% with a quarter left, about 11% on the stone bubble, and under 5% right after the bubble burst.
That is one setup, but the shape holds. Pressure builds slowly, spikes at the bubble, and drops as soon as you cash.
You’ll also see the same idea expressed as bubble factor, which compares what you lose with what you gain. Converting one to the other is plain arithmetic. For an all-in with no extra money in the pot, a bubble factor of 1.5 means you need 60% equity instead of 50%, which is a 10% premium. A bubble factor of 2.0 means about 67%, which is a premium of about 17%.
A Bubble Call Worked Out
Everyone folds to a 40 big blind stack in the small blind, who shoves. You have 10 big blinds in the big blind, and there are no tiny stacks at the table.
You’re calling 9 big blinds to win a pot of 21, so with no payouts involved you’d need about 43% equity. Suppose the bubble adds a risk premium of 12%. Your requirement becomes about 55%.
Even against a very wide shoving range, only a fairly tight group of your strongest hands clears that bar. That’s why calling ranges collapse on the bubble while shoving ranges stay wide. When you shove, you can win without a showdown. When you call, you have to win the showdown.
Satellite Bubbles vs Regular Tournament Bubbles
A satellite takes everything above and turns it up as far as it goes. Every qualifier wins the same seat, so chips beyond what you need to survive are worth almost nothing.
That’s why folding kings, or even aces, the strongest of all poker hands, can be correct on a satellite bubble when your stack is safe and short stacks are all in against each other. If one of them busts, you win your seat without risking a chip.
A regular tournament is different. There, a medium stack calls with aces every time, because a double up gives you a real chance at the big prizes at the top. Our guide to poker satellites covers each stage in detail.
Three Bubble Hand Examples
Hand 1. Folding a Shoving Hand With 20 Big Blinds
It’s the stone bubble. A loose, aggressive big stack raises, and you have 20 big blinds with a hand you’d normally reshove without a second thought.
Now look at the table. One player has three big blinds. The others have 15, 8, 30, and 13. The three big blind stack has to win two or three all-ins in a row to survive, and in a big field there are more stacks like that at other tables.
You’re close to a lock to cash, so fold. Don’t call to see a flop either. Even when the shove works, the reward doesn’t justify the risk of bubbling.
Hand 2. Check-Calling Queens on a Final Table Bubble
On the bubble of a $25,000 buy-in event, a 20 big blind stack limped pocket queens in the small blind, and Adrian Mateos checked eight-six offsuit in the big blind with one of the largest stacks.
The flop came seven-five-three with two clubs. The short stack checked, Mateos bet one big blind, and the queens just called. With no payouts in play, that is an easy check-raise. As the covered player on a bubble, check-calling keeps the pot small.
The turn paired the five, Mateos bet four big blinds, and the queens called again. The river paired the seven, and Mateos moved all in. After a long think, the queens folded.
In theory, that river is close to break-even with queens. The lesson is in the earlier streets. When you’re the shorter stack on a bubble, you check and call a lot, and you accept that some rivers will be ugly.
Hand 3. Keeping Chips Behind With a Full House
In a $25,000 event that paid eight places, we were one elimination from the money. I had pocket eights and about 31 big blinds. A player who covered me limped, I raised, a 15 big blind stack called from the big blind, and the limper called.
The flop came queen-jack-jack, and all three of us checked. The turn was an eight, giving me a full house. The short stack bet four of his remaining 11 big blinds, the limper called, and I just called to keep them both in.
On the river, the short stack moved all in. In a normal spot, my hand is an all-in every time. Here I only called and kept about eight big blinds behind.
The short stack had aces, and the limper had queen-jack for a bigger full house, so I lost the pot. But the short stack was out, and those eight big blinds were enough to cash a hand or two later when a player at the other table busted. Getting a few more chips in with a huge hand was worth far less than the chips I saved.
Conclusion
Poker bubble strategy comes down to that one check before every decision. If you cover the players left in the hand, raise small and often. If you’re covered, fold the close ones and keep pots small. If you’re short, count the stacks below you first.
Don’t overvalue the minimum cash, though. The players who win the most take a calculated risk before the bubble when it sets up a big stack, and then they lean on everyone who is waiting to cash.
Once the bubble bursts, the pressure drops and you should get back to accumulating chips. It builds again as the real money gets closer, which is where how to play near the final table picks up, along with the rest of your late stage tournament strategy.
