Chess culture

Not awarded yet: Royal Walkabout, Brilliant!!, The Carlsen Grind, Short’s King Walk.

Homages to chess memes, famous games and Samarkand lore, meant kindly. Brilliant!!, Botez Gambit and The Carlsen Grind use Lichess’s analysis of 60 of 64 finished games; the rest look at every finished game.

moves of endgame

Averages per game, with the phases split as Lichess splits them. 66% of the games reached an endgame; the first capture came on move 7.7 on average.

Endgames by type

EndgameReachedAt the end
Queen and rook63
Rook53
Queen44
King and pawn31
Bishop30
Knight21

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.
