Collections

Averages per game, with the phases split as Lichess splits them. 71% of the games reached an endgame; the first capture came on move 6.3 on average.

Endgames by type

EndgameReachedAt the end
Rook11
King and pawn00
Queen00
Bishop00
Knight00
Queen and rook00

A rook endgame has nothing but kings, pawns and rooks left; the others likewise, as the Lichess puzzle tagger defines them. A game can pass through several types, so the first column adds up to more than the games.

Reached, and still there at the end

Each band runs from the games that reached the endgame to those that still had it on the last move; the rest went on into another type. One scale for both columns.

Every opening of the round

The round’s openings as a tree: the five volumes of the opening encyclopaedia (A flank openings, B semi-open games, C open games and the French, D closed games and the Grünfeld, E Indian defences), their families, and every variation played. A line grows with the games through it; the red thread leads to the round’s rarest openings.

Which openings won

A bar per family: White’s wins, the draws, Black’s wins. The tick is the family’s score for White, the grey line the round’s; a tick right of it, and White did better than usual. Framed in red, the best for White and the best for Black of the families with at least 5 games.
