Volatility control
Chess K-Factor Calculator
Come usare questo calcolatore
Use the Chess K-Factor Calculator to estimate which K-factor fits a player profile. The tool checks age, game count, current rating, and whether the player has reached 2400, then explains why the likely K value changes rating volatility.

Why K-factor matters
K-factor controls how strongly the rating system reacts to one result. A high value makes ratings move quickly for new or improving players, while a low value keeps established ratings more stable.

How to read the recommendation
The recommendation is a rules-style guide, not a replacement for official federation processing. Use it to understand why K=40, K=20, or K=10 may apply before calculating expected rating change.
