Across every rating and clock, the Bongcloud Attack family scores 35.3% for White — we are 90% confident the real figure is between 35.0% and 35.6% — from 61K Lichess games across 1 variations. 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: 61K+ 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.
