Tournament simulation software allows players to practice different scenarios in a risk-free environment, helping them refine decision-making and adjust to varying stack sizes, blind levels, and opponent tendencies. It enables the testing of strategies by analyzing expected values and long-term profitability of different plays. Players can replay hands, study optimal strategies, and recognize patterns in real-time decision-making. By simulating deep runs and late-stage situations, users develop experience and confidence in high-pressure moments, ultimately improving their overall tournament performance.
