How ELO Works

The ELO system calculates your new rating based on your expected performance versus your actual result.

The Rating Formula
R' = R + K × (S - E)
R'
Your new rating after the game
R
Your rating before the game
K
K-factor (determines volatility)
S
Actual score (1=win, 0.5=draw, 0=loss)
E
Expected score based on ratings

Tips to Improve Your Rating

Consistent improvement comes from focused practice and smart game selection.

Study Your Games

Analyze your losses to find patterns. Understanding your mistakes is the fastest path to improvement.

Play Longer Games

Rapid and Classical give you time to think deeply. Quick games build bad habits.

Master One Opening

Know one opening deeply rather than many superficially. Consistency builds confidence.

Practice Tactics Daily

Tactics win games. Spend 15-30 minutes daily on puzzle training to sharpen pattern recognition.

Rating is Just a Number

Don't obsess over rating fluctuations. Focus on improvement and the rating will follow naturally. Short-term variance is normal - your true skill level is shown over many games.
