Bubble

Quick facts by PokerStrategy

• The bubble in poker is the stage of the tournament that occurs when there are only one or a few players left before the money.
• Whoever busts on the bubble leaves with nothing, whereas the rest of the field take at least the min-cash.
• Action tends to slow right down on the bubble as players attempt to make the money before taking risks.
• Your poker bubble strategy should depend on whether you have a short stack or big stack.

What Is a Bubble in Poker?

The bubble in poker is the stage of a tournament that occurs when there are only one or a few players left to be eliminated before the rest of the field makes the money.

• Soft Bubble: The “soft” bubble is the term used when the tournament is reaching the money, but there are still a few more players left to bust.
• Stone Bubble: The “stone” or “hard” bubble is when the tournament has exactly one more player left to bust before the rest of the field makes the money.

The dynamics of the game will shift when the bubble approaches, as players adopt tighter strategies in an attempt to make money.

The poker bubble also brings with it hand-for-hand play, which ensures everyone is dealt the same number of hands during this crucial phase of the tournament. Depending on the size of the field, hand for hand may start on the soft bubble or stone bubble.

Poker Bubble Example

1. A poker tournament has a field of 400 players, and 50 players are set to make the money.
2. The tournament reaches the “soft” bubble with around 55 players remaining.
3. The stone bubble starts when 51 players are left.
4. Once a player has been eliminated in 51st place, the bubble bursts and normal play resumes.

Bubble in Poker Importance

With the poker bubble explained, let’s look at why it is so important and how it can shift the dynamics of gameplay:

• Payouts: The bubble in poker represents the threshold between making money and not making money. Surviving the bubble is of utmost importance, as doing so will grant you a guaranteed payout.
• Tournament Dynamic: Instead of focusing on gaining chips, short and medium-stacked players will rightly be more concerned with survival. The action will usually tighten up dramatically.
• ICM: The concept underlying this shift in dynamics is known as the Independent Chip Model (ICM), which determines the cash value of chips at any point. The bubble is a crucial moment in which ICM pressure is very high. In short, preserving your stack becomes more important than chip accumulation.
• Psychological Pressure: Because short and medium stacked players should (correctly) tighten up, big stacked players can apply a lot of pressure by raising or shoving, as other players won’t want to bust before the bubble bursts and should not be calling light.

Poker Bubble Strategy & Tips

How you approach the bubble will depend on your chip stack in relation to everyone else’s.

Short Stack Poker Bubble Strategy

Even with very few chips, your stack will soon be worth at least the min-cash if you can just make the money. Your priority is therefore to survive the bubble. You can take more risks to build your stack as soon as it bursts.

Whether you can easily make it through by tightening up depends on both the blinds and your opponent’s stack. Consider how many orbits of blinds you can take before you become desperate, and how likely it is that other players will bust before you.

At the same time, don’t pass up high-value hands that could secure you an ITM finish if you double up, or be prepared to steal blinds if required to lock up your place. You’ll still have some fold equity against other short stacks who are looking to survive.

Medium Stack Poker Bubble Strategy

Medium stack players have much to lose on the money bubble in poker, as busting now would be very costly regarding EV and win rate. You’ll want to avoid unnecessary confrontations against players who can knock you out, especially when it comes to making big calls.

With a medium stack, you can still apply pressure to shorter stacks by shoving and to medium stacks by raising. Just be careful not to overcommit and put yourself in a precarious situation when you don’t need to make any moves.

Big Stack Poker Bubble Strategy

With a big stack on the bubble in poker, you can run rampant over a short-stacked table, taking advantage of the fact that your opponents (correctly) want to play tight to make the money. Short and medium stacked players will be forced to fold out most of their hands against you for fear of busting.

This is a great opportunity to gain chips that can be used to make a serious run in the tournament. Observe the table dynamics at all times and stick to pushing around short stacks, while still avoiding all-ins against those who can cause damage.

Satellite Bubble Strategy

Satellite bubbles are an extreme version of a normal tournament bubble. In a satellite, the payout structure is completely flat. For example, in a 300-player tournament, 30 players all get the top prize of entry to a higher-cost tournament.

Focus on survival; even premium hands can be folded if you are already safe. Poker bubble play in a satellite can get very tight, and it can even be correct to fold premium hands if you can already make it through.

Common Mistakes During Bubble Play

Frequently or unnecessarily busting before the bubble in poker is very costly for your win rate.

Here are some of the most common mistakes players make during bubble play:

• Ignoring the Bubble: The biggest mistake you can make during the bubble is to ignore it and continue playing your usual strategy. This will lead to you taking risks that could cost you an ITM finish.
• Blinding Out: Survival is the main aim of poker bubble strategy, and that often means folding. However, with a very short stack, the blinds can cause serious damage and leave you desperate. You may still need to make shoves to stay alive.
• Calling too Wide: One of the main implications of ICM during bubble play is that you shouldn’t be taking marginal spots, such as calling wide, especially against opponents who can damage your stack or bust you out.
• Missing Spots with a Big Stack: If you have a big stack on the bubble, you’re in an ideal situation. It will be hard, if not impossible, for you to bust in one hand, and it would take a series of disasters to bust before the money. Don’t make the mistake of missing out on opportunities to push around opponents who are just trying to survive.

What Happens When the Bubble Bursts?

When the bubble bursts, the player who was eliminated on the bubble leaves the tournament with no prize money.

Depending on the rules, if two or more players bust during the same hand during the bubble, the player with the fewest chips is eliminated first, or the min-cash is split between the bustouts.

The rest of the field has made it through to the money. It’s an exciting time, as the min-cash usually more than covers the initial entry fee. After securing the min-cash, now’s your chance to make a deeper run for substantial prizes, especially if you’ve locked up a decent stack to play with.

When the poker bubble bursts, hand-for-hand will stop, and normal play will resume. ICM becomes less of a factor, and you should switch back to attempting to accumulate chips. There may also be a flurry of eliminations as short-stacked players who made the money start to take risks to either double or bust.

Bubble Play in Online vs Live Tournaments

The poker bubble rules are the same for an online tournament as they are for a live tournament. Hand-for-hand play will begin at a defined moment and will last until the bubble bursts. The rest of the table will make the money.

This process will occur automatically when playing online poker on leading poker sites, whereas in a live game, the dealers, floor staff, and tournament director will oversee the bubble. Regarding strategy, live players tend to feel even more invested in the bubble than in an online tournament, as they have travelled to the casino and perhaps paid for accommodation.

Of course, this all depends on table dynamics. In live poker, you’ll be able to observe physical tells and watch who is folding often, compared to playing lots of hands.
