Open event at the 42nd Chess Olympiad

The number of registered teams set a record of 180 teams representing 175 countries, however 10 of these did not arrive so the actual participation was 170 teams. Azerbaijan, as host nation, fielded three teams, whilst the International Braille Chess Association (IBCA), the International Physically Disabled Chess Association (IPCA), and the International Chess Committee of the Deaf (ICCD) each provided one team.[8] Ten FIDE Member Federations did not have teams at the Olympiad. They include the triple champions (2006, 2008 and 2012) in the open event Armenia as well as Bhutan, Burundi, Cambodia, Comoros, Gabon, Laos, Nauru, Solomon Islands and East Timor. The Netherlands Antilles, albeit a non-existing entity since 2010, were allowed to field teams under this name, because the Curaçao Chess Federation remains officially registered as representing the dissolved country in the FIDE Directory.[9] Eritrea, Kosovo, and South Sudan debuted at the Chess Olympiads.[2]

Notes

The tournament featured eight out of the top ten players from the FIDE rating list published in August 2016; only former World Champion Vishwanathan Anand and Levon Aronian were missing the Olympiad. Among the players who were playing in the open section were the World Champion and highest rated player in the world Magnus Carlsen, the challenger in the World Chess Championship 2016 Sergey Karjakin as well as the former World Champions Vladimir Kramnik and Veselin Topalov. Grandmaster Eugenio Torre was in the line-up of the Philippines for the record twenty-third time, having played on each Chess Olympiad since 1970 except in Dresden in 2008.[10] On the other hand, Ukraine were weaker for Vassily Ivanchuk, who does not play for the first time after 14 consecutive Olympiads (1988-2014) and 13 appearances on board one (1990-2014). The former World Champion Challenger and leader of the Israeli team in 8 consecutive Olympiads (2000-2014) Boris Gelfand was also missing the Olympiad following a conflict with the Israeil Chess Federation management.[11][12]

The strongest team of the tournament were Russia with an average rating of 2760. Captained by the president of the Russian Chess Federation and FIDE Vice President Andrey Filatov, the team consisted of the World Champion Challenger Sergey Karjakin, Vladimir Kramnik, Alexander Grischuk, Evgeny Tomashevsky and Ian Nepomniachtchi. Seven-time Russian Champion and the fourth highest ranked Russian player Peter Svidler was not included in the team. The United States were the second strongest team with three top ten players, Fabiano Caruana, Hikaru Nakamura and Wesley So, along with Ray Robson and Samuel Shankland. So and Shankland had proved prior to the Olympiad that they were in good form after winning the Sinquefield Cup 2016 and the Biel Chess Festival 2016, respectively. The defending champions China were the third team with highest average rating and the only team besides Russia whose all players had rating higher than 2700. They participated with the same line-up that won the gold medal except for Ni Hua who was replaced by Li Chao. The first team of the three that represented the host country Azerbaijan was the fourth strongest and completed the group with an average rating exceeding 2700 points. The only change in their line-up from the previous Chess Olympiad was Arkadij Naiditsch, a board one player for Germany in four Olympiads, who was playing instead of Gadir Guseinov.[13]

After 10... c3?!, White left the knight on d2 in the lurch and played 11. axb5!.

The results in the first round generally reflected the huge rating disparities between the paired teams, the majority of the higher rated teams scoring perfect 4-0 results even without their top players. Several other top teams conceded a single draw, winning by 3½-½ margins. The world's top four players, Magnus Carlsen, Maxime Vachier-Lagrave, Fabiano Caruana and Vladimir Kramnik, all did not play in the opening round. Norway showed signs of frailty after conceding two draws against Wales to win 3–1, while Serbia beat Trinidad and Tobago by the same margin following GM Nikola Sedlak's upset loss to Kevin Cupid. The biggest surprise of the first round, however, was Bulgaria's draw against Sudan. Veselin Topalov and Krasimir Rusev won their games with the White pieces but Momchil Nikolov and Martin Petrov lost with the Black pieces.[18][19] On the lower boards, the team from South Sudan impressed in their Olympiad debut against the Faeroe Islands, scoring an upset win on board 3 and a near-upset on board 1 despite a minimal budget, no coach, and little apparent knowledge of opening theory.[18]

There was a larger than usual number of no-shows in the first round, particularly among the African teams. Several teams were unable to field the required three players and forfeited all four games; these were Malawi, Cameroon, Mali, Haiti, Sierra Leone, Liberia, Burundi, Senegal, Gambia, Congo, Djibouti, Lesotho and Mexico (who thereby lost to the much lower-rated Ivory Coast). Teams who had informed the organizers that their players had not arrived were not paired; these were Angola, Madagascar, Uganda, Kenya, Rwanda, Seychelles, Eritrea, and Central African Republic. A few teams arrived with only three players, gifting their opponents a point; Russia's fourth board Alexander Grischuk won in this fashion against Nigeria, as did Spain's David Antón Guijarro against Syria.[18][19] Some of these teams later arrived, often with only three players; by the first rest day 10 teams had still not arrived, for a total participation of 170 teams.

One of the best games of the day was Wei Yi's win on board four to help China score a 4–0 victory against the first-time entrants Kosovo. In the game, he sacrificed a piece in the opening for an overwhelming compensation that enabled him to finish the game in 19 moves (see diagram).[20]

In this position, Adams played 137... Qd2? instead of the winning 137... Kf1+! followed by 138. Kh1 (138. Kh3 Kg1! 139. Qb1+ Qf1+ wins) Qf2! 139. Qb1+ Qe1 140. Qc2 e2 141. Qf5+ Qf2 142. Qb1+ e1N! (if Black promotes to other piece, White draws with 143. Qd3+ with perpetual check).

There was a number of stiff matches with closer fight and more balanced opposition in the second round, although top seeded teams continued scoring high victories. In general, all teams with higher average rating playing on the first 28 tables met their Elo expectations and defeated their opponents.[21] Russia, Azerbaijan, Poland and India scored perfect victories against Turkmenistan, Macedonia, United Arab Emirates and Costa Rica, respectively. The United States and China dropped half point, because American Sam Shankland critically blundered in his game against the Scot Colin McNab but somehow managed to survive and Chinese Wei Yi played a game with many oscillations against Belgian Nicola Capone that seemed he might have lost but ended in a draw. England faced difficulties in narrowly beating Indonesia 2½-1½ after Luke McShane lost to Irwanto Sadikin and Michael Adams drew his 166-move game against Muhammad Lutfi Ali. The game could have been won for Adams had he spotted a nice combination including an underpromotion on move 137 (see diagram).[22] The matches between Iran and Georgia, Slovakia and Greece, and Mongolia and Finland were all tied.[23][24]

It was also the round in which the top four players on the FIDE rating list make their debut: Magnus Carlsen, Maxime Vachier-Lagrave, Fabiano Caruana and Vladimir Kramnik. Out of them, only Maxime Vachier-Lagrave was held to a draw to Irish grandmaster Alexander Baburin but France still managed to defeat Ireland convincingly by 3½-½. Carlsen opened his game with the move 1. e3!? but brought the game to a winning position with an overwhelming attack before any material was sacrificed and helped Norway beat Bangladesh minimally by 2½-1½.[25] Caruana faced a Four Knights Game with 4. Be2, an opening that he has never seen before, but at the end still won the thrilling game against Andrew Greet of Scotland.[24]

The issue with the incomplete pairing was handed down from the first to the second round and 14 African teams remained unpaired, meaning that the total number of teams actually playing was 166 instead of 180 as expected, which was 10 less than at the previous Chess Olympiad.[24]

White could have simplified this position to a winning endgame had he played 64. f5! with the idea of 64... gxf5 65. c7 Nc1 66. Rxc1 Rxe2+ 67. Kg3 Rg2+ 68. Kf4. Nonetheless, Mareco opted for a pawn push and played 64... c7? that led the game to be drawn.

The matches of the third round were closely contested by higher-rated teams with many of them having four grandmasters vs. four grandmasters boards. They resulted in a total of 16 teams extended their winning streak to three starting wins.[26] Russia managed to set Moldova back from any surprise and scored a 3–1 win thanks to the wins by Ian Nepomniachtchi with the Black and Alexander Grischuk with the White pieces on the lower boards. Azerbaijan beat Hungary with the same score in a match with four decisive games, where Shakhriyar Mamedyarov, Rauf Mamedov and Arkadij Naiditsch defeated Richárd Rapport, Csaba Balogh and Benjamin Gledura, respectively and Zoltán Almási brought Hungary a full point for beating Teimour Radjabov.[27]

United States and China both scored a 3–1 win against two South American teams, Argentina and Brazil. The American players earned success against Argentina with the White pieces as Fabiano Caruana defeated Fernando Peralta on board one and Wesley So defeated Federico Perez Ponsa on board three. Ray Robson played a move with the wrong rook to give Diego Flores a chance to play for a win but the position still looked holdable for Black and the game was drawn with a perpetual check.[28] Hikaru Nakamura suffered in most of the game after Sandro Mareco outplayed him in the opening and brought the game to a winning position being two pawns up; however, on move 64, he missed a clearance idea to give his king more space that would have resulted in a win (see diagram).[29] In contrast to the United States, the Chinese players won their match against Brazil as a result of two wins with the Black pieces and two draws. Wang Yue won a 114-move long game against Alexandr Fier,[30] while Yu Yangyi escaped from a worse position against Evandro Amorim Barbosa and even won after the Brazilian blundered with his king on move 37 and resigned immediately.[31][32]

The participants in the World Chess Championship 2016 Magnus Carlsen and Sergey Karjakin were both held to a draw. Unlike Karjakin whose team would have won had he even lost his game, Carlsen did not save his team who lost to Romania 2½-1½ as Aryan Tari was beaten by Bogdan-Daniel Deac. The World Champion was pressing in his game as Black against Constantin Lupulescu and got a slight edge, which he was unable to convert to a win and the game ended in a draw. Besides Norway, other strong teams that lost minimally were Germany to Ukraine and Poland to Cuba. Only one decisive game brought Ukraine the win, in which Andrei Volokitin won as White against German Daniel Fridman on board four. Cuba's win over Poland was decided on the boards three and four, where Yuniesky Quezada and Isan Reynaldo Ortiz Suárez beat Mateusz Bartel and Dariusz Świercz, respectively; the only full point for Poland came from board two, where 18-year old Jan-Krzysztof Duda defeated Lázaro Bruzón to keep his perfect score with 3 out of 3 at the Olympiad. Canada's strong start with 8 out of 8 games won in the first two rounds ended with a 2½-1½ loss against England. Michael Adams and Gawain Jones won their games as White, while David Howell lost and Nigel Short successfully defended a worse position throughout much of the game.[33]

Tomashevsky blundered a pawn in this position with 33. Rh3??, which was followed by 33... hxg4 34. fxg4 Rxh4 35. Rxh4 Bxh4. Ponomariov managed to convert the advantage and thus to decide the match.

The fourth round was marked by the encounter between the six-time Olympic champions Russia and two-time Olympic champions Ukraine on the first table. Russia approached the match without Sergey Karjakin, who played for Ukraine in three Olympiads in the past and won a gold medal with the team in 2006, while Ukraine did not have Yuriy Kryvoruchko in the line-up. The match started well for the Russians as Ian Nepomniachtchi succeeded to convert his slight edge into a winning position against Anton Korobov by spotting a mating net around the opponent's king to win his game with the Black pieces.[34] Nevertheless, the result was not standing for long, because Andrei Volokitin defeated Alexander Grischuk, who spent more than an hour on moves 10–12, in a rook endgame with three strong connected pawns on the e-g files.[35] On the other two boards, it seemed that only Pavel Eljanov had some winning chances against Vladimir Kramnik on the top board but Ruslan Ponomariov won a pawn against Evgeny Tomashevsky and converted the advantage into a full point.[36] After Tomashevsky resigned and the Ukrainian team took the lead, Eljanov gave up from putting pressure on Kramnik and agreed to a draw. Ukraine narrowly won the match 2½-1½.[37][38] Following the end of the match, Ukrainian president Petro Poroshenko spent no time to hail the victory on his Twitter account.[39]

The second seeded team of the United States were held to a 2–2 tie by the Czech Republic in a match with four draws. Azerbaijan and China both scored a 3–1 win against Romania and Italy, respectively to continue their winning run. Azerbaijan's victory came as a result of Shakhriyar Mamedyarov's crushing win over Constantin Lupulescu with the Black pieces on the top board and Arkadij Naiditsch's strong performance against Vlad-Cristian Jianu with the White pieces on board four. The Chinese had two decisive games in their favour on the first two boards as Wang Yue beat Danyyil Dvirnyy in a superb positional display to secure his third win against a grandmaster in three games and Ding Liren defeated Axel Rombaldoni.[37] The second table hosted the battle between the strong Indian and Cuban teams, which resulted in a tight victory for India with three draws and a single win scored by 21-year old Vidit Santosh Gujrathi over Yuniesky Quezada, who recorded his fourth win in the fourth game.[39] The clash between 6th seeds England against 11th seeds the Netherlands was also one of the interesting pairings of the day but ended in a surprisingly 3½-½ win for the Dutch team. England, who were playing without Nigel Short, scored only one draw on the top board in the game between Michael Adams and Anish Giri. On the other boards, Erwin l'Ami, Loek van Wely and Benjamin Bok all defeated David Howell, Luke McShane and Gawain Jones, respectively. In the other interesting matches, Belarus narrowly beat Latvia thanks to Sergei Zhigalko's win against Alexei Shirov on board one, Serbia and Slovenia played a tied match, while Croatia were surprisingly beaten by lower-rated Mongolia as former European champion Zdenko Kožul lost as White to Tsegmed Batchuluun.[40][38]

World champion Magnus Carlsen drew Australia's David Smerdon but his team snatched a minimal win against Australia, because Frode Urkedal beat Max Illingworth on the lowest board. The winless day for the strong players was completed with Maxime Vachier-Lagrave who played a game that he could not win against Ioannis Papaioannou in the 2–2 draw with Greece, while Veselin Topalov was beaten by Baadur Jobava in Bulgaria's 3–1 loss to Georgia.[38]

In this position, Jones made a positional queen sacrifice by playing 15... fxe3!?, managing to get a strong attack. The game continued with 16. Nxe8 exf2+ 17. Ke2 Ng3+ 18. Kd3 Rxe8 19. Kc2 Bd7 20. Bc4 Ba4+ 21. Bb3 Bb5 and Black won after 32 moves.

Three teams, the Netherlands, Ukraine and India, continued their victorious runs and scored their fifth match win. After closely defeating the first seeds Russia in the previous round, Ukraine beat another strong opponent in the name of the reigning Olympic champions China by 2½-1½. The only decisive game in the match was Yuriy Kryvoruchko's win with the White pieces against Yu Yangyi on the third board. The Netherlands had also a close encounter with Belarus with only one decisive game in favour of the Dutch team. The game was played between Kiril Stupak and Benjamin Bok on the fourth board. Black was better out of the opening, which mostly accounted for the unsafe position of the White king, and even sacrificed a rook for a direct attack. The game turned around at some point as Black did not succeed to properly coordinate his pieces in the attack and White appeared to be winning. Nonetheless, White committed himself to a series of mistakes that left Black with a very powerful attack despite being a rook down that resulted in a Black's win.[41][42] It was Bok's four win in the fourth game he played.[43] India continued their winning streak after stunning the hosts Azerbaijan 3-1 thanks to two wins with the Black pieces. Pentala Harikrishna beat Shakhriyar Mamedyarov and Vidit Santosh Gujrathi defeated Arkadij Naiditsch to score his fifth win at the Olympiad.[44][45]

Russia recovered after their loss to Ukraine in the previous round to beat Egypt 3-1 and so did England who beat Vietnam with the same result after the heavy loss to the Netherlands. Sergey Karjakin and Ian Nepomniachtchi both won for Russia with the White pieces on board one and board three, respectively, while Gawain Jones and Nigel Short scored full point on the lower boards. Especially remarkable was Gawain Jones' win over Nguyễn Ahn Khoi with a positional queen sacrifice on move 15 for two minor pieces and the attack (see diagram).[46][43] United States beat Serbia 3-1 thanks to the early wins by Hikaru Nakamura and Wesley So. Georgia extended their winning run with a crushing win 3½-½ against Spain, where only José Carlos Ibarra Jerez was able to hold Tornike Sanikidze to a draw. The upsets of the day are Cuba, Hungary and France who all lost to lower-rated Canada, Latvia and Paraguay, respectively.[45] Cuba's Leinier Domínguez won against Canada's Evgeny Bareev on board one but his teammates lost on all other boards. Latvia scored two wins against Hungary on the first two boards, where Alexei Shirov beat Richárd Rapport as White and Igor Kovalenko defeated Ferenc Berkes; Csaba Balogh's win against Vladimir Sveshnikov on board four was enough just for minimal loss for his team. France's Maxime Vachier-Lagrave scored his first win at the Olympiad after three draws but his team suffered a 2½-1½ loss from Paraguay as Sébastien Mazé and Romain Édouard both lost.[42][44]

Jan-Krzysztof Duda of Poland scored an impressive win against Moldova's Viorel Iordăchescu to join grandmasters Vidit Santosh Gujrathi, Hjorvar Steinn Grétarsson and Ian Nepomniachtchi as only players scoring 5 out of 5 in the first five rounds.[43] In a game that was opened with the Berlin Defence of the Ruy Lopez with Steinitz's 4. d3, Duda came with an original idea on the move 11, which allowed him to develop a strong play with his rooks on the c-file and later sacrifice an exchange on c6 to get a winning position.[47] Despite his win, the match ended in a tie.[42]

l'Ami blundered in this position with 36. Rd1??, overlooking the pin of the bishop and dropping the important pawn on c4. Adhiban immediately grabbed the pawn on c4 and forced the exchange of rooks with 36... Bxc4 37. Bf3 Rxd1+ 38. Bxd1. l'Ami resigned after 66 moves.

The central match in the sixth round receiving the attention was the clash between India and the Netherlands. The Dutch players started strong on all boards, especially Anish Giri who put Pentala Harikrishna in serious trouble on the first board, but the Indians defended well. After three draws, the only decisive game was played on the second board, where Baskaran Adhiban beat Erwin l'Ami with the Black pieces after the Dutch blundered an important pawn on the move 36 and put himself in a lost endgame (see diagram).[48][49] Ukraine, who were the third team with a perfect score before the round, lost 2½-1½ to the United States, which allowed India to become sole leader and the only team with perfect match score after six rounds. Similarly to the match between India and the Netherlands, there was only one decisive game played on the first board, where Fabiano Caruana silently outplayed Pavel Eljanov in a position that seemed equal but later transposed into a winning endgame with a passed a-pawn.[50] Caruana said that he was not better at all and that 19... Rf6 was step in the wrong direction for Black, followed with the weird 29... Rxe6. He also added that it was "by far" the biggest win he had ever had for the United States.[51]

Czech Republic and Georgia split the points with four draws. Azerbaijan and Greece also played a match that ended 2-2 but with one decisive game per side. Shakhriyar Mamedyarov and Teimour Radjabov drew their games on the top two boards against Dimitrios Mastrovasilis and Hristos Banikas, respectively. Arkadij Naiditsch had a good start of the tournament with four wins but suffered his second loss in a row in the game against Athanasios Mastrovasilis after losing track of the complications that occurred in an old line of the Benoni Defence. However, Eltaj Safarli saved the day for the Azeri team with his win over Stelios Halkias.[51] On the other boards, Canada continued with their strong performance by beating Belarus 2½-1½ as a result of the Eric Hansen's win against Andrey Zhigalko on board three; China edged out Argentina with the same result thanks to Ding Liren and Li Chao who scored full points against Federico Perez Ponsa and Diego Flores, respectively, but Wang Yue lost to Sandro Mareco with the White pieces on board one;[49] Norway tied with the Philippines in a match resulting in four draws, where Julio Catalino Sadorra held World champion Magnus Carlsen to a draw.[52] Carlsen got a small edge out of the opening but did not manage to cash in from it and put himself in an inferior position with a pawn down that he was still able to hold. After the game, Sadorra commented:

It was only time trouble that kept me from converting the advantage… It's me against me. The only reason I will lose or not find good moves is me.[53]

Russia defeated Germany 3–1 with two wins with the White pieces on boards two and four, where Vladimir Kramnik beat Georg Meier and Ian Nepomniachtchi beat Daniel Fridman.[52] Meier opened the game with the French Defence but Kramnik sacrificed a piece for two pawns and a strong initiative right out of the opening that resulted in a winning endgame with a pawn up.[54] Fridman opted for the Petrov's Defence in his game against Nepomniachtchi and played well until the time control but then he went for a passive set-up with his pieces and allowed the Russian to win the endgame.[55] It was Nepomniachtchi's sixth win at the tournament, making him the only player with perfect score after six rounds.[51]

Navara played a novelty in this position with 13... d5?!, weakening the square c5 and allowing Karjakin to exchange the dark-squared bishops and occupy the square with a knight. The game was followed by 14. Nb3 b5 15. Be3 Bxe3 16. Rxe3 Rd6 17. Nc5 with lasting advantage for White.

The seventh round was marked with the high 3½-½ victories of the top two seeds Russia and the United States against the Czech Republic and the only team with a perfect score and sole leader in the standings India, respectively. The three wins for the American team came from the games played from the second to the fourth board, where Hikaru Nakamura beat Baskaran Adhiban, Wesley So defeated Vidit Santosh Gujrathi and Sam Shankland beat S. P. Sethuraman; the game on the first board between Pentala Harikrishna and Fabiano Caruana was drawn. However, it did not seem to be a one-sided match as the final result may indicate, because the Indian players even had chances to win the games on the first and the fourth board. Caruana had a worse position during most of the game and seemed to be in trouble but Harikrishna mistakenly offered a queen exchange on move 35 that blew out his advantage.[56] Shankland was in a desperate position against Sethuraman but the Indian was not able to finish the game and started making mistakes in the time trouble to lose his huge advantage and end up in an inferior position being two pawns down that resulted in a loss.[57] Shankland said after the game that he was considering to resign but played on, because it was a team event with more on the line than just a personal result. He added that he had saved games with that bad position in the past but not against someone of Sethuraman's strength.[58][59]

Russia snatched the high victory thanks to the wins on the first three boards, where Sergey Karjakin, Evgeny Tomashevsky and Ian Nepomniachtchi beat David Navara, Viktor Láznička and Zbyněk Hráček, respectively; on the lowest board, Vlastimil Babula drew with Alexander Grischuk. Navara went with a novelty right out of the opening that weakened his position and allowed Karjakin to find a strong outpost for his knight on c5 (see diagram).[60] The game was over after 24 moves as the Czech committed himself to several blunders in the already worse position. In an interview after the game, Karjakin stated that he felt "honoured" to play on the first board "in such a great team".[58] Nepomniachtchi continued the perfect score with his seventh win in a game with opposite-coloured bishops. The position seemed equal but Nepomniachtchi manoeuvred around putting pressure on his opponent, who made mistakes that allowed the Russian to get a winning advantage.[61][62][59]

On the second table, Latvia upset the higher-rated Netherlands with a 3–1 win resulting from the games with the Black pieces, in which Igor Kovalenko beat Loek van Wely and Nikita Meskovs beat Benjamin Bok. The match between Azerbaijan and Croatia ended in a 3½-½ victory for the host team with full points scored by Teimour Radjabov, Rauf Mamedov and Eltaj Safarli. Georgia beat Romania 3–1 with the wins by Baadur Jobava, who scored his fourth win in six games on board one, and Levan Pantsulaia with the White pieces. England defeated China 3-1 as well thanks to the wins by Michael Adams, who squeezed out a win from a seemingly equal position, against Wang Yue as White on the top and Nigel Short, who won the sharp battle with double-edged positions, against Li Chao as Black on the lowest board.[63] Canada provided strong resistance against Ukraine with Evgeny Bareev's win over Pavel Eljanov with the Black pieces on the top board; however, Anton Korobov and Andrei Volokitin won on the lower boards to earn Ukraine a minimal match victory. Norway also won with a minimal result against Turkey thanks to the World champion Magnus Carlsen who checkmated Dragan Šolak as Black on the top board.[64][58]

In this position, where it seems that the White rook on e7 is trapped, Jobava found a brilliant idea with 17. Bh6!! and a strong attack to follow. The game continued with 17... gxh6 18. Qxh6 Rxc3 19. Qg5+ Kf8 20. Qxf6 Rxd3 21. cxd3 and Ponomariov resigned.

The attention in the eighth round was centred on the match between the top two seeds and tournament leaders after seven rounds Russia and the United States that ended 2–2. After about an hour of play, it was clear that the game between Hikaru Nakamura and Vladimir Kramnik on the second board was heading to a draw as Nakamura did not manage to get an opening advantage in a game with a solid Queen's Gambit Declined for Black. Kramnik, however, continued playing in a drawn position until the draw was agreed after 42 moves.[65] The clash between Sergey Karjakin and Fabiano Caruana was more interesting, because Karjakin put some pressure on his opponent but was not able to find a clear win. The decisive games were played on the lower boards. On board four, Alexander Grischuk managed to score a full point with the Black pieces against Ray Robson after the American played too passively in the time trouble, making a miscalculation on move 38 when he decided to liquidate the opponent's knight and allowed Grischuk to get a winning position with a passed e-pawn.[66][67] It was the first individual loss for the United States at the Olympiad. On board three, Wesley So obtained a nearly decisive advantage with the Black pieces in the opening, which he later converted into a win against Ian Nepomniachtchi who had won all seven games previously played at the Olympiad.[68][69][70]

On the second table, Ukraine beat Georgia 3-1 thanks to the wins from the second to the fourth board, where Yuriy Kryvoruchko, Anton Korobov and Andrei Volokitin defeated Mikheil Mchedlishvili, Levan Pantsulaia and Tamaz Gelashvili, respectively. Nevertheless, Baadur Jobava scored full point for Georgia with his fifth victory in the seventh game against Ruslan Ponomariov. The Ukrainian tried a new idea and was doing fine out of the opening but one sloppy allowed Jobava to grab the initiative that turned into a brilliant attack with a bishop sacrifice (see diagram).[71] After the game, Jobava declined a press conference, saying that his moves were better than his thoughts. India edged out England 2½-1½ thanks to S. P. Sethuraman's win over Nigel Short on the fourth board in the only decisive game of the match. Both Ukraine and India joined the United States on the top of the standings.[69][67] The highest rated host team Azerbaijan snatched a 2½-1½ victory in their match against Latvia with Eltaj Safarli beating Nikita Meskovs on the last board. China suffered their third loss at the tournament after losing minimally to Hungary with Zoltán Almási's win over Li Chao with the Black pieces. Norway continued their steady rise with a 3–1 victory against Peru as a result of the three wins scored by Magnus Carlsen, Aryan Tari and Frode Urkedal.[72][70]

Several matches on the higher tables were drawn, including Italy versus Iran, Greece versus Slovenia and Canada versus Vietnam.[72][70] It is interesting that, with four wins and four draws, Greece remained the only unbeaten team other than the United States after eight rounds.[67]

This is the position after Firouzja played 26... Rd1, not paying attention to a possible back-rank mate, which allowed Jones to exchange rook for two minor pieces after 27. Rxe5 Bxe5 28. Nc6 Re8 29. Nxe5 with advantage he was able to convert.

The ninth round concluded with the United States and Ukraine on the top of the standings as a result of their match victories against Norway and India. The United States beat Norway 3–1 in a match with two draws and two wins with the Black pieces. On the top board, the match hosted the encounter between Magnus Carlsen and Fabiano Caruana in which the World champion surprised his opponent by opening the game with the Scandinavian Defence. Caruana said after the game that he hardly remembered the theory beyond the opening, in which Carlsen even played a novelty on move 8. He managed to comfortably equalise the position and the game ended in a draw.[73] On the second board, Jon Ludvig Hammer got into an unpleasant position against Hikaru Nakamura that the American converted into a full point. After the game, Nakamura explained that his opponent had probably mixed up the variants and that he should have not allowed exchange of the light-square bishops. The game between Frode Urkedal and Sam Shankland on the lowest board did also end in favour of the American team after Urkedal made some strange moves in a Sicilian Najdorf that allowed his opponent to snatch the win.[74] Shankland said that he noticed his opponent had only played 1. e4 seven times in his life and was not ready to handle the complexities of the Najdorf position that arose.[75][76] Ukraine won the battle with India by 2½-1½ with the only decisive game played on the last board. The game between S. P. Sethuraman and Anton Korobov was still being played after all games on the first three boards had ended in a draw. The game opened with a Rauzer Sicilian that lead to a difficult endgame with advantage for Korobov who was able to convert it with the Black pieces.[77] He said that he was unable to properly evaluate the position but after the time control he realised he was close to winning.[75]

On the other tables, Russia defeated the strongest team of the host Azerbaijan by 3-1 thanks to the wins by Vladimir Kramnik and Alexander Grischuk both with the White pieces over Teimour Radjabov and Arkadij Naiditsch, respectively.[78] The game between Shakhriyar Mamedyarov and Sergey Karjakin was also interesting but the Russian succeeded to hold the game.[76] Iran and England tied their match with two decisive games played on the lower boards, where Shahin Lorparizangeneh beat Luke McShane for Iran and Gawain Jones defeated Alireza Firouzja for England. On the fourth board, 13-year old untitled Firouzja missed a decisive tactic on move 26 that allowed Jones to win the game (see diagram).[79] Czech Republic minimally defeated the Netherlands 2½-1½ with the only win scored by Viktor Láznička against Erwin l'Ami and so did Georgia who beat Hungary with the same score as a result of the wins on the first two boards by Baadur Jobava and Mikheil Mchedlishvili. Jobava reached a result 7 out of 8 with a rating performance of 3013, second highest at the Olympiad after Capo Vidal Uriel's of Mexico.[78][75] The matches Latvia versus Slovenia, Italy versus Chile and Greece versus Turkey all ended with even scores.[80]

In this position, Shankland played a novelty with 16. Qf2! that helped him consolidate in the game and win the Black h-pawn after 16... Qd7 17. Rae1 Ne7 18. e4 h4 19. Nh1 Ng6 20. e5 Nh5 21. Bc1 Nhf4 22. Bxf4 Nxf4 23. Qxh4. Sanikidze resigned on move 39.

The matches of the penultimate round saw the United States and Ukraine winning to reach the final round tied for the first place with 18 match points each. The United States beat Georgia 2½-1½ thanks to the wins scored by Wesley So and Sam Shankland on the lower boards. Sam Shankland was the first to score a full point after beating Tornike Sanikidze with the White pieces in a game in which he played a novelty on move 16 that allowed him to quickly win a pawn and get rid of his bad bishop at the same time (see diagram).[81] Wesley So won with the Black pieces against Levan Pantsulaia in a game that he equalised and managed to get an advantage after Pantsulaia blundered a pawn on move 14.[82] After the game, So said that his opponent lost on time but in a lost position. On board two, however, Hikaru Nakamura lost with the White pieces to Mikheil Mchedlishvili as a result of a bad move played in the opening that did not give him a chance to bounce back into the game.[83] On the second table, Ukraine defeated the Czech Republic 3–1 with two wins on the first and the last board, where Pavel Eljanov beat David Navara as Black to reach an individual score of 50% and Andrei Volokitin defeated Vlastimil Babula as White for an individual score of 7½ out of 8 with a rating performance of 2994.[84]

Russia had just one match point deficit to the leaders before the round and still had hopes for stealing the gold in the last minute but their hopes were dashed in the match against India that ended in a 2–2 tie. The Russian team were even trailing after the World Champion Challenger Sergey Karjakin lost to Pentala Harikrishna on the top board.[84] Yet, Vladimir Kramnik beat Baskaran Adhiban in a King's Indian Attack, where the Indian was playing anti-positionally in the opening. He put all his pawns on light squares and traded his bishop on h5 for a knight on f3 on move 11 but switched on the colour controlled by his remaining bishop after the position opened up. Kramnik knew how to deal with it and converted his advantage to a win.[85] England narrowly beat Azerbaijan 2½-1½ with wins by Gawain Jones and Nigel Short against Arkadij Naiditsch and Eltaj Safarli, respectively; Rauf Mamedov defeated David Howell to score the only full point for the Azeri team, while Michael Adams and Shakhriyar Mamedyarov drew their game. Norway won with a huge margin against Iran 3½-½ with three wins by Magnus Carlsen, Aryan Tari and Frode Urkedal. Hungary minimally defeated the Netherlands 2½-1½ with only one decisive game played on board three, where Csaba Balogh beat Loek van Wely with the White pieces in a game that lasted 113 moves. Canada continued their strong performance with a 3–1 victory over Latvia. Alexei Shirov beat Evgeny Bareev on the first board for Latvia but Anton Kovalyov, Alexandre Lesiège and Eric Hansen all won on the lower boards to secure the match victory for their team.[83][86]

Besides Russia versus India, other matches on the higher tables that ended in a tie were China versus Belarus and Greece versus Spain. The defending Olympic champions disappointed once again as Li Chao suffered his third consecutive loss at the Olympiad. Spain was ahead of Greece thanks to Francisco Vallejo Pons who beat Ioannis Papaioannou on the top board but the Greek team struck back with the win scored by Stelios Halkias against Renier Vázquez on the lowest board. Thus, Greece remained the only unbeaten team along with the United States before the final round.[86][87]

Sethuraman blundered a piece in this position by playing 16... Bxe3+??, overlooking that after 17. Qxe3 Bg4 he does not win the piece back because of 18. Be5. The Indian resigned on move 25.

Two teams, United States and Ukraine, entered the final round tied for the first place with 18 match points, while Russia was in third place with 16 match points. The United States narrowly defeated Canada 2½-1½ with Fabiano Caruana and Wesley So both as White beating Evgeny Bareev and Alexandre Lesiège on board one and three, respectively; Anton Kovalyov and Hikaru Nakamura drew their game on the second board, while Eric Hansen scored a full point for Canada against Sam Shankland on the lowest board. Caruana outplayed Bareev in the quickest game of the match, while Nakamura managed to defend a slightly worse endgame against Kovalyov. On the third board, So sacrificed an exchange in his game against Lesiège with all three results being realistic at some point but the game ended with a full point for the American team, while Hansen beat Shankland in a game in which the American did not get anything from his theoretical pawn sacrifice on the last board. Ukraine did also win their final match with a convincing 3½-½ victory over Slovenia thanks to the wins by Pavel Eljanov, Anton Korobov and Andrei Volokitin against Alexander Beliavsky, Jure Borišek and Matej Šebenik, respectively. Russia defeated Italy 3-1 thanks to the victories scored by Vladimir Kramnik and Alexander Grischuk.[5][88]

In the other matches of the final round, Norway and India exchanged one win each for a 2–2 tie. The match score was decided on the lower boards as the games between Pentala Harikrishna and Magnus Carlsen as well as Jon Ludvig Hammer and Baskaran Adhiban were drawn. Frode Urkedal scored the first win in the match after S. P. Sethuraman blundered a piece, overlooking a simple response by his opponent (see diagram).[89] Vidit Santosh Gujrathi, however, equalised the result after defeating Aryan Tari. Azerbaijan and France scored 3-1 victories against Turkmenistan and the Czech Republic, respectively, while Turkey minimally beat Georgia 2½-1½. The matches involving Peru and England as well as Greece and Hungary ended in a tie. Greece remained the only unbeaten team at the tournament along with the United States, scoring four wins and seven draws.[90][91]
