Methodology

Across every level and clock, the Bongcloud Attack family scores 35.5% for White, with a range running from 35.3% to 35.8% around that figure, from 91K rated Lichess games across 1 variations. Win rate, draw rate and loss rate come from games played September 2023 to August 2026.

How the figures are made

Whose games these are: 91K rated games played on Lichess (2023-09 to 2026-08). The games are Lichess’s and free for anyone to use. What is ours is the reading of them. Last rebuilt September 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.
What the Floor and Edge at worst are: The Floor is the worst score you would still get, 90% confident: the low end of a figure’s range, not its average. Edge at worst is how far wins run ahead of losses, 90% confident, so above zero, that side wins more than it loses even on a bad day. Each is stated for the rating and clock shown, over the games that reached the position. They are on different scales: a score sits at 50 when the sides are level, an edge at zero.
How much we need before we say anything: An opening page needs 100 games. A figure on it needs 100 games at its rating and clock: short of that the answer reads a wider scope and says so, a table row shows only its count, and a map cell shows a dash. Under 1.0K games a figure is drawn faint, and never leads a list or counts as the best or worst place the line wins. The chaos and trap lists need 500 games overall and 250 games at one rating or clock.
