The bubble phase significantly impacts strategy in tournaments, as players become increasingly cautious and focused on survival, rather than accumulation of chips. This shift in mindset leads to tighter play, reduced aggression, and a greater emphasis on preserving stack size. As a result, you need to adapt by becoming more selective with starting hands, reducing bluffing frequency, and focusing on value betting opportunities, all while being mindful of the increased importance of chip preservation and minimizing risk during this critical phase.
