3 more, tied

Most pawn moves by one side while the game was still in its opening.

Ratings, titles and ages

Not awarded this round: GM Scalp.

Chess culture

Never Play f6

31% scored by all who tried

4 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.

Not awarded this round: Botez Gambit.

Homages to chess memes, famous games and Samarkand lore, meant kindly. Brilliant!!, Botez Gambit and The Carlsen Grind use Lichess’s analysis of 365 of 366 finished games; the rest look at every finished game.

En passant was on the board and the player left it alone. En passant is forced, allegedly.

Poisoned Pawn

Not awarded this round: Il Vaticano, Pawn Cube, The Hard One.

The awards that list every case instead of crowning one, read from the position on every move; the overview counts them across the rounds. The Hard One, Il Vaticano, the pawn shapes and Royal Court may well stay empty for a round or two.

Averages per game, with the phases split as Lichess splits them. 67% of the games reached an endgame; the first capture came on move 7 on average.

Queen and rook1812

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.
