Lichess analysed 406 of 406 finished games, with 2,029 inaccuracies, 816 mistakes and 953 blunders. Times come from the relay clocks of 400 games. The extra 30 minutes after move 40 showed up on move 41 or 42 for 67% of 371 players, and never for 72 players who went past move 45.

Game awards

Player awards

Ratings, titles and ages

Clock awards

Not awarded this round: Flag Fall.

From the relay clocks of 400 of 406 finished games; games with missing, hand-entered or corrected clocks are left out, and time left after move 40 counts only once the clock shows the extra 30 minutes.

Engine awards

From Lichess’s computer analysis of 406 of 406 finished games. Inaccuracies, mistakes and blunders are the ones Lichess marks on the move.

Chess culture

Never Play f6

50% scored by all who tried

7 more, tied

Ben Finegold says never push the f-pawn one square. These players did it by move 10 (f3 or …f6) and won anyway.

Brilliant!!

4points of material given

1 more, tied

A real sacrifice: the piece was taken at once and the player stayed at least two points down, yet Lichess found nothing wrong with the move. The biggest gift wins.

Homages to chess memes, famous games and Samarkand lore, meant kindly. Brilliant!!, Botez Gambit and The Carlsen Grind use Lichess’s analysis of 406 of 406 finished games; the rest look at every finished game.

Averages per game, with the phases split as Lichess splits them. 84% of the games reached an endgame; the first capture came on move 6.9 on average.

Rook6449

Queen and rook2811
King and pawn2517

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.
