Many beginners believeLosing in a row means you're not playing well.ActuallyEven if positive EV decisions are consistently made, a prolonged downswing may still occur.
Variance affects short-term outcomes, not the quality of decisions.
What is Variance?
Variance, in Chinese it is calledfluctuation,It meansThe natural difference between short-term actual results and long-term expected values due to probability.
Variance is not an error, but a normal phenomenon of probability.
Why does variance occur?
The main reasons include:
→ Every hand is random.
→ Even with an 80% win rate, you might still lose.
→ Insufficient short-term sample size
→ Luck influences short-term results
The larger the sample size, the closer the result is to the true EV.
What is the relationship between Variance and EV?
EV stands forLong-term average return
Variance representsShort-term results fluctuate around EV.
EV determines the direction, Variance determines the process.
What are the characteristics of variance?
Commonly included:
→ Downswing (loss streak)
→ Upswing (winning streak)
→ Bad Beat
→ Cooler
→ Long-term profit and loss fluctuations
Every player will experience fluctuations, just to varying degrees.
How do experts deal with variance?
Professional gamers will pay attention to:
→ Bankroll Management
→ Sample size
→ EV Analysis
→ Emotional control
→ Continuous review
→ GTO and Exploit Strategies
Experts control decision-making, not luck.
Practical Example
You hold A♥ A♠,All-in before the flip, opponent holds K♣ K♦
Even with AA's win rate of approximately 801 TP3T, there's still a chance of losing with approximately 201 TP3T.
That's the power of variation, not a mistake in strategy.
The Most Common Misconception Among Beginners
Many players believeA losing streak indicates a failed strategy.In factIf the long-term EV remains positive, then the short-term losing streak is simply part of the variance.
Do not use short-term results to negate correct decisions.
Core Conclusion
Variance is an unavoidable probabilistic phenomenon in Texas Hold'em, and a long-term challenge that all players must accept.
Understanding the concepts of Variance, Expected Value, Equity, Downswing, Upswing, Bankroll Management, GTO, and Exploit will help you view wins and losses from a long-term perspective, remain unaffected by short-term fluctuations, and continuously improve your true profitability.
