Preparing for the bubble and late stages in the middle game requires adjusting to ICM pressure, stack sizes, and opponent tendencies. As the bubble approaches, short stacks play tighter to secure a min-cash, while big stacks apply pressure to exploit this hesitation. Recognizing these dynamics allows for strategic aggression, stealing blinds and attacking medium stacks that are reluctant to risk elimination. Maintaining a healthy stack ensures flexibility for deep-run opportunities, while avoiding unnecessary confrontations with other big stacks minimizes volatility.
