How these numbers work
- Score: a win counts 1 and a draw ½, divided by the games played in that opening.
- Expected score (“ratings predict”): what the Elo formula predicts from both players' ratings in those games. A score more than 5 percentage points above it is green, more than 5 below is red, anything in between is on par.
- Performance (Perf): the average opponent rating + 800 × (score − 50%), a simple linear estimate; the average opponent is shown beside it.
- Sample size: key findings use openings with 5 or more games. How much to trust this score: fewer than 10 games is a small sample and only a hint, 10 to 29 is a medium sample, 30 or more is a solid sample.
- Games: finished Chess.com games, up to 150 as White and 150 as Black, grouped by opening and time control.
