Variance

Variance in poker refers to the natural fluctuations in results caused by the inherent randomness of the game. Even when making optimal decisions, players can experience periods of winning and losing streaks due to the distribution of cards and outcomes. This concept is crucial to grasp, as it helps players manage expectations and avoid tilt during downswings.

‍Positive vs. Negative Variance:

- Positive Variance: When results are better than expected.

- Negative Variance: When losses occur despite good play. Managing variance effectively involves having a sufficient bankroll, adopting a long-term perspective, and avoiding emotionally-driven decisions during difficult stretches.
