Methodology
Across every rating and clock, the Nimzo-Indian Defense: Dilworth Gambit scores 48.6% for White — we are 90% confident the real figure is between 48.2% and 49.1% — from 29K Lichess games. Win rate, draw rate and loss rate come from games played December 2023 to November 2025.
How the figures are made
- Whose games these are
- 29K+ rated games played on Lichess (2023-12 to 2025-11). The games are Lichess’s and free for anyone to use. What is ours is the reading of them. Last rebuilt January 2026.
- Which games we count
- Rated games only — nothing casual.
- Both players within 200 rating points of each other. A mismatch tells you about the gap, not about the opening.
- At least 2 moves played.
- A game is filed under White’s rating.
- Why every number comes with a range
- A number off a few hundred games is a guess. The same number off millions is a fact. The range is what tells them apart, and it is what the lists rank on — so an opening cannot reach the top on a lucky run of forty games. The more games behind a figure, the narrower its range.
- How much we need before we say anything
- An opening page needs 100 games. A gambit needs 50 games at a rating before we will say whether it pays there. The chaos and trap lists need 500 games overall and 250 games at one rating or clock.
