The stress of live and online poker differs significantly due to the environment, pace, and psychological dynamics involved. Live poker tends to be slower, giving players more time to think, read opponents, and feel social pressure, which can create stress through face-to-face interactions and the need to manage physical tells. Online poker, on the other hand, is much faster-paced, often with players multi-tabling, which can lead to mental fatigue and decision overload. Additionally, the anonymity of online play can increase tilt due to bad beats or aggressive opponents, while live games may add emotional pressure through public scrutiny. Each format tests a different kind of mental endurance and emotional control.
