Left out of the statistics: Dotse Sumya Ibrahim – Ella Miceli-Farrugia — the broadcast did not record the moves that were played. The result 1–0 stands (verify, 28 Sep: board 59.4 Dotse – Miceli-Farrugia scored 1-0 (chess-results agrees) but the relay's moves end 32. Qc4 with Black +6.24, a move after Black's 31... Qxd2 had left White a mate in one; the relay mis-registered moves).

Left out of the statistics: Samiro Mohamed Ali – Vernesa James — the broadcast did not record the moves that were played. The result 1–0 stands (verify, 28 Sep: board 82.2 Samiro – James scored 1-0 (chess-results agrees) but the relay's moves end 39... Nxh3+ with Black +6.84 and 28:46 on her clock after the time-control bonus; the recording stopped before the end).

Left out of the statistics: Tiania Kukula – Ginger Jubitana — the broadcast did not record the moves that were played. The result ½–½ stands (by hand, 28 Sep (Sam): board 84.4 Kukula – Jubitana drawn (chess-results agrees) but the relay's moves end 38... Qxf6 with Black +9.09, a queen for a rook up with 27:09 on her clock; the game ended in a way the relay did not record. A draw has no loser, so verify does not name it).

Left out of the statistics: WFM Kler Caku – Salma Lagmou — the broadcast did not record the moves that were played. The result 1–0 stands (by hand, 28 Sep (Sam): board 45.2 Caku – Lagmou scored 1-0 (chess-results agrees) but the relay's moves end 11. hxg3 in a level Caro-Kann Exchange, with no clock time on any move and no Lichess analysis; the recording stopped before the end. It stood as the section's quickest win of the event).

Engine awards

From Lichess’s computer analysis of 285 of 371 finished games. 86 more join when the round is updated the next evening. Inaccuracies, mistakes and blunders are the ones Lichess marks on the move.

Chess culture

Never Play f6

53% scored by all who tried

12 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!!

2points of material given

4 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 285 of 371 finished games; the rest look at every finished game.

Holy Hell

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

Poisoned Pawn

5pawn grabs

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.
