What is Bubble in poker?

The bubble phase in a poker tournament is an extremely tense period just before the money-paying positions are reached, where one more player needs to be eliminated for everyone else to cash. This stage introduces immense ICM (Independent Chip Model) pressure, dramatically altering optimal strategy. Short-stacked players often tighten up drastically, aiming to survive into the money, while big stacks can exploit this fear by aggressively opening pots and putting pressure on medium and short stacks. Mastering bubble play involves a delicate balance of aggression and survival, recognizing which players are vulnerable to shoves and which are likely to call, to maximize your own tournament equity. Effective bubble strategy is crucial for long-term tournament success and maximizing prize money.
