Left out of the statistics: WCM Merisena CadeauBintou Diallo — the broadcast did not record the moves that were played. The result 1–0 stands (verify, 19 Sep: board 242 Cadeau – Diallo scored 1-0 (chess-results agrees) but the last recorded eval, after move 35, has Black +5.38 after a −5.6/+12.9 swing; the relay mis-registered a move).

Never Play f6

42% scored by all who tried

8 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: The Carlsen Grind.

Homages to chess memes, famous games and Samarkand lore, meant kindly. Brilliant!!, Botez Gambit and The Carlsen Grind use Lichess’s analysis of 371 of 371 finished games; the rest look at every finished game.

Averages per game, with the phases split as Lichess splits them. 81% of the games reached an endgame; the first capture came on move 7 on average.

Endgames by type

EndgameReachedAt the end
Rook6243
Bishop3528
Queen and rook3311
King and pawn2212
Queen2017
Knight199

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.
