Round 6 in numbers

Uzbekistan and India came in first and third, and the match turned on board 3, where Nodirbek Yakubboev beat Nihal Sarin in 54 moves. Replay The other three were drawn: Abdusattorov and Praggnanandhaa in 40, Gukesh and Shamsiddin Vokhidov in 40, and Erigaisi Arjun against Javokhir Sindarov in 34, which at 2759 against 2778 was the highest-rated game of the round. Replay That is 2½–1½ to Uzbekistan, and they are the only team in the Open still on a perfect score.

China beat Germany 3–1 and took the best team performance of the round, 2877 against opposition averaging 2677. Ding Liren, 31 points the underdog, beat Vincent Keymer on board 1 in 50 moves, and Xu Xiangyu won board 4 against Alexander Donchenko. Replay

The other board-1 scalp was the biggest of the day by rating: Denis Lazavik of Belarus, 2621, beat Jan-Krzysztof Duda, 2743, in 68 moves. Szymon Gumularz won board 2 back for Poland and the match finished 2–2. Replay

France and England drew 2–2 the busy way. Vachier-Lagrave and Vitiugov drew board 1 in 33 moves, then Michael Adams beat Etienne Bacrot and MarcAndria Maurizzi beat Gawain Jones, both in 55, one win each on boards 2 and 3. Replay Romania and Hungary shared it the same way: Peter Leko beat Constantin Lupulescu on board 2, Filip Magold beat Tamas Banusz on board 4, and Rapport and Deac drew in 31.

Armenia beat Iran 2½–1½ with three draws and a win for Gabriel Sargissian on board 4. Replay The USA got past Norway 2½–1½ on Hans Niemann's 69-move win, but the game to look at there is board 4: Tor Fredrik Kaasen was six points of material down against one, and drew it. Replay

China did to Poland what they had just done to Germany in the Open: 3½–½ against the second seed, and the best team performance of the section. Song Yuxin needed 27 moves on board 2 against Aleksandra Maltsevskaya, and Lu Miaoyi and Yan Tianqi won boards 3 and 4. Replay

India beat the USA 3–1. Vantika Agrawal beat Irina Krush in 65 moves, Savitha Shri won board 4 against Rose Atwell, and Humpy Koneru and Carissa Yip drew the highest-rated game of the section in 54. Replay

Kazakhstan beat Azerbaijan 2½–1½ on Alua Nurman's board-2 win over Gunay Mammadzada, with Bibisara Assaubayeva drawing board 1. Replay They and China are the two perfect teams left.

Georgia beat Uzbekistan 3½–½ with wins on the bottom three boards, and France beat Vietnam 4–0. Ukraine beat England 2½–1½, where Anastasiia Hnatyshyn and Bodhana Sivanandan drew board 1 having given away six centipawns between them over 55 moves, the cleanest game of the section. Replay

My favourite game of the round was nowhere near the top boards. Rachelle Hoareau of the Seychelles was born in 1955, which makes her the oldest player in the Women's section. Her opponent, Bambaouma Maissane of the Comoros Islands, was born in 2014. That is 59 years across one board, the widest gap of the round in either section.

Hoareau won in 20 moves with a smothered mate, the one where the king is walled in by its own pieces and a knight does the rest. Five games in the round ended in a mate with a name, and hers was the only smothered one.

Miora Andriamasoandro of Madagascar and Daqi Mao of New Zealand played 130 moves and drew. The endgame started on move 40 and ran for 91 of them, the longest of the round. Between moves 98 and 116 Mao gave 19 checks in a row, also the most of the round, and the king survived all of them. And on move 95 both sides promoted within three moves of each other, which the site calls a Photo Finish. Four awards, one board, half a point each. Replay

Andriamasoandro also played the 126-move draw that took the Marathon in round 2. Some people just do not resign, and I am glad of it.

Baadur Jobava spent 62 minutes on 46.Kf2 and drew. Replay Franchesca Ramirez Luzon of the Dominican Republic spent 69 minutes on 17...Nxe4 and lost. Replay At the other end, Tebou Tata Itaaka of Kiribati won with two hours and four minutes still on his clock.

Layla Yasmira Caicedo Rios of Panama promoted to a bishop on move 50, 50...d1=B, and won. Replay There were two underpromotions in the round; the other was a knight with check, which is the one that usually has a reason behind it.

Rozak El of Cambodia built a Pawn Diamond on move 22: four pawns around an empty square, one below, two beside, one above. It is from r/AnarchyChess, it happened once in 778 games, and it is the rarest thing on the board today. Replay

Seventeen games had a third queen on the board at once, which the site calls Royal Court. Nobody managed The Hard One, the bishop-and-knight mate against a bare king. That has happened once all event, in round 2, when Maili-Jade Ouellet of Canada finished with 109.Bc6# after 109 moves. Every winner of it is here.

That France and England board 1 was the cleanest game of the Open as well: Vachier-Lagrave and Vitiugov gave away five centipawns between them over 33 moves. Vitiugov lost two of the five, which was 99.5% accuracy and the best of the round. Replay

Then there is board 234. Eldiyar Orozbaev of Kyrgyzstan had a mate in 19 against Alejandro Jose Chinchilla of Honduras, played 72.Qg8, and was suddenly the one getting mated, in one move. Chinchilla played 72...Ke4 and missed it. Orozbaev won. That is the biggest blunder of the round, the best swindle and the luckiest escape, all on the same move pair, and the heartbreak award goes to the man who had mate in one and went for a walk instead. Replay

In the Women's section, Mary Salamatu Farmer of Sierra Leone had mate in eight, played 42.Kf1, and lost. Replay

Uzbekistan lead the Open on 12 match points and 19½ game points, from China on 11 and 18½ and Armenia on 11 and 17. In the Women's section China lead on 12 and 20½, with Kazakhstan level on match points and two behind on games.

There were 24 whitewashes in the Open and 21 in the Women's section. Niger won three of their four games by checkmate on the board, which is the Finishers award and takes some doing. Uzbekistan's four boards were the most accurate of any team in the Open, 97.8%.

Lichess analyses every finished broadcast game on its own servers, and by the evening 99.9% of Open moves had an evaluation; the Women's section was still being analysed as I wrote this, so its accuracy and blunder numbers will settle overnight. Relay clocks are chaos, so the script looks for the jump where the 30-minute bonus actually lands instead of trusting move 40. Ties are shown instead of broken, and every award links to the exact move.

This round is a good one for explaining forfeits. Ten games were not played, four in the Open and six in the Women's section, the most since round 1. A forfeit is a real result: it counts for match points, for board points and for the standings. It never counts for anything about the moves, because there were none, so the averages, the accuracy and every award here are over the 778 games that were actually played. Both Israeli teams were among them this round. Yom Kippur ran from Sunday evening to Monday nightfall, and FIDE's own round-5 report described both teams playing early and away from the main hall to observe it; round 6 falls on the day itself, and the relay records 4–0 walkovers to the Netherlands and to Bulgaria. One result was corrected from the official tables tonight, a Women's game the relay scored the wrong way round although its own last move was checkmate, and three more games' moves are out of the statistics because the relay did not record them faithfully.

Tomorrow is the rest day, so the next round is Wednesday. Every round gets its own page, there are team standings with the official tie-breaks, and an overview of the whole event tracks the records as they fall. The site is unofficial and not affiliated with FIDE, the organisers or Lichess.

Got an idea for an award? Lichess comments and the r/chess round thread both reach me. One from the round 1 comments already made it in.

And thanks again to the Lichess broadcast team. Without the relay, none of this exists.
