The open event at the 43rd Chess Olympiad was held from 24 September to 5 October 2018. It was contested by a record number of 185 teams, representing 180 nations. ^[1] Georgia, 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. A total of 920 players participated in the open event. ^[2]

China won the gold medal in the open event for the second time after they previously claimed the title in 2014. They scored eight wins, two draws and one loss for a total of 18 match points. The same result was achieved by the United States and Russia, who had inferior tie-breakers and came up on the podium by winning the silver and bronze medal, respectively. ^[3] Jorge Cori of Peru, playing on board three, was the best individual player in the open event by scoring 7+1/2 out of 8 points (seven wins and one draw) with a rating performance of 2925. ^[4] The other gold medalists include Ding Liren of China on board one who scored 5+1/2 out of 8 points with a rating performance of 2873, Nguyễn Ngọc Trường Sơn of Vietnam on board two who scored 8+1/2 out of 10 points with a rating performance of 2804, Daniel Fridman of Germany who scored 7+1/2 out of 9 points with a rating performance of 2814, and Anton Korobov of Ukraine as reserve player who scored 6+1/2 out of 8 points with a rating performance of 2773. ^[5]

Competition format and calendar

The tournament was played in a Swiss system format. The time control for all games was 90 minutes for the first 40 moves, after which an additional 30 minutes were granted and increment of 30 seconds per move was applied. Players were permitted to offer a draw at any time. A total of 11 rounds were played, with all teams playing in every round. ^[6]

In each round, four players from each team faced four players from another team; teams were permitted one reserve player who could be substituted between rounds. The four games were played simultaneously on four boards, scoring 1 game point for a win and ½ game point for a draw. The scores from each game were summed together to determine which team won the round. Winning a round was worth 2 match points, regardless of the game point margin, while drawing a round was worth 1 match point. Teams were ranked in a table based on match points. Tie-breakers for the table were i) the Sonneborn-Berger system; ii) total game points scored; iii) the sum of the match points of the opponents, excluding the lowest one. ^[6]

Tournament rounds started on 24 September and end edwith the final round on 5 October. All rounds started at 15:00 GET (UTC+4), except for the final round which started at 11:00 GET (UTC+4). There was one rest day at the tournament, on 29 September after the fifth round. ^[7]

Teams and players

The open section of the tournament was contested by a record number of 185 teams, representing 180 nations. ^[1] Georgia, as host nation, have 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) have each provided one team. ^[8]

The tournament featured nine out of the top ten players from the FIDE rating list published in September 2018 with only then-World Champion Magnus Carlsen being absent. Former World Champion Viswanathan Anand returned to the Chess Olympiads on board one for India following a break of twelve years. ^[9] Other players who are playing in the open section include the former World Chess Champion Vladimir Kramnik, the upcoming challenger in the World Chess Championship 2018 Fabiano Caruana, as well as the former challengers Sergey Karjakin and Boris Gelfand. Grandmaster Eugenio Torre, who was in the line-up of the Philippines for a record twenty-three times in the 1970-2016 period and was the highest-scoring player at the 42nd Chess Olympiad, decided not to play and was named coach of the Philippines national team in the open section. ^[10] Former FIDE World Champion Veselin Topalov was not playing because a dispute between chess officials caused de-recognition of the Bulgarian Chess Federation by FIDE. ^[11]

This was the first time Russia had not been the top-ranked team before the start of a Chess Olympiad since their first entry in 1992 following the dissolution of the Soviet Union, conceding the top spot to the United States who are defending the title won at the previous Olympiad. United States are playing with the same line-up that won the gold medal with Fabiano Caruana, Hikaru Nakamura, Wesley So, Samuel Shankland and Ray Robson, whose average rating of 2777 was also the highest in the history of Chess Olympiads. Russia as the second strongest team have made changes in the line-up compared to the Baku Chess Olympiad, where Dmitry Jakovenko and Nikita Vitiugov have replaced Alexander Grischuk and Evgeny Tomashevsky along Vladimir Kramnik, Sergey Karjakin and Ian Nepomniachtchi. China have the third highest pre-tournament rating of 2752 and four players from Baku on the team, including Ding Liren, Li Chao, Wei Yi and Yu Yangyi, while Wang Yue was replaced by Bu Xiangzhi. Other teams among the top seeds with average ratings above 2700 are Azerbaijan led by FIDE Grand Prix 2017 winner Shakhriyar Mamedyarov, India strengthened with Vishwanathan Anand, and Ukraine with Vassily Ivanchuk and former FIDE World Chess Champion Ruslan Ponomariov on the team. ^[12]

As is common in the first round of an Olympiad, several of the poorer federations were unable to field teams. Omitted from the pairings were Nigeria, Pakistan, Ivory Coast, Rwanda, Somalia, Burundi and Congo. ^[13] Maldives and Togo were unable to field the required three players and forfeited their matches. Reflecting the disparity in strength between the teams, there were no upsets on the team level; all the higher ranked teams won. The majority of matches ended in 4–0 score lines, although several teams conceded draws. The biggest upset of the round was the defeat of Chinese grandmaster Li Chao, who misplayed a drawn endgame against Morocco's Mohamed-Mehdi Aithmidou. Another grandmaster to suffer a defeat was the Canadian Aman Hambleton, who lost to the Nepalese player Rijendra Rajbhandari. ^[14] The best game prize, awarded each round by a committee headed by Susan Polgar, was awarded to Davit Maghalashvili of the Georgia 2 team for a spectacular combination against Renato Frick of Liechtenstein, who resigned rather than allow the combination to be played out. ^[15]

Amid reports that the Pakistan team had been prevented from leaving their country due to internal politics, ^[16] all the teams except Pakistan were paired for the second round. ^[17] On the top board, the top-seeded team from the United States struggled against Georgia's number three team, who were rated on average over 300 Elo lower – only Wesley So was able to score the full point. The second-seeded Russian team also conceded two draws against Ireland, Russian-born grandmaster Alexander Baburin holding Sergey Karjakin on the top board while IM David Fitzsimmons held Dmitry Jakovenko on board 4. An upset occurred in Hungary vs Albania when Peter Leko, after refuting Erald Dervishi's unsound tactics, blundered in a won position; the match ended in a 2–2 draw. Another notable player to lose was David Navara, who went down to Tajikistan's Farrukh Amonatov, however Czech Republic still won the match by a 3–1 margin. In his first Olympiad game in 12 years, Viswanathan Anand defeated Austrian grandmaster Markus Ragger, helping the Indian team to a 3½–½ win. ^[18] At the conclusion of the round 41 teams had won both their matches, including seven teams with perfect 8/8 game results. ^[19] Brazilian grandmaster Alexandr Fier was awarded the daily best game prize for a mating combination against Robert Aloma Vidal of Andorra involving a double rook sacrifice pattern described by chessvibes reporter Peter Doggers as "common in kids books but exceedingly rare in actual chess!" ^{[20] [18]}

Round 3

The highest rated clash was between the top-seeded United States and 13th-seeded Netherlands. The game between the super-GMs Anish Giri and Fabiano Caruana was uneventful and the match was looking to be heading for a draw until two of the Dutch players erred in the endgame, handing the US a 3–1 win. China defeated Peru 3–1, Ding Liren making his comeback following a bicycle accident in Norway, however Wei Yi lost to Jorge Cori. Russia edged out the Georgia 2 team by a margin of 2½–1½, needing Vladimir Kramnik to provide the match win. India comfortably defeated Canada while England edged out Brazil when Gawain Jones held a difficult endgame against Krikor Mekhitarian. France took the overall lead by defeating Algeria 3½–½, for a total game score of 11½/12, closely followed by Israel who beat Iceland by the same margin for a score of 11. A total of 18 teams had perfect match scores of 3/3. ^[21]

Round 4

The top encounter of the fourth round took place on the third table, where the United States recorded a 2½-1½ but comfortable win over India. Pentala Harikrishna and Krishnan Sasikiran drew their games with the white pieces against Wesley So and Samuel Shankland, respectively, in less than two hours. ^[22] The game between Hikaru Nakamura and Vidit Santosh Gujrathi also ended in a draw, while on top board Fabiano Caruana defeated Vishwanathan Anand in 26 moves. ^[22] Poland provided an upset against Russia, as Kramnik and Dmitry Jakovenko fell to Jacek Tomczak and Kamil Dragun. ^{[23] [24] [25]} China, Azerbaijan, Ukraine and France maintained their winning starts, at the expense of Croatia, England, Argentina and Vietnam. The Czech Republic defeated Iran, despite David Navara taking a rest; Viktor Láznička stepped up to board 1 and scored the decisive win over world junior champion Parham Maghsoodloo. Israel and Armenia both recorded 3–1 wins in their matches against Sweden and Greece to remain on maximum board points. ^[22]

Round 5

The fifth round saw another upset, as the China–Czech Republic match ended 1–3. Yu Yangyi was outplayed by Láznička, while Jiří Štoček capitalised on a mistake to win with black against Wei Yi. Poland continued their strong form by defeating France 3–1, and Azerbaijan edged out their rivals Armenia 2½–1½. The United States were held to a draw by Israel, which left Ukraine as the only other team to maintain their winning streak after they defeated Spain. ^[26]

Round 6

The four remaining teams on a perfect score faced off against each other. Azerbaijan recorded a convincing 3–1 victory over the Czech Republic, while Poland defeated Ukraine thanks to 20-year-old Jan-Krzysztof Duda's 32-move win against Vassily Ivanchuk. The United States bested Bosnia and Herzegovina 3½–½, with the only negative being Nakamura's draw to IM Dejan Marjanović. Russia–India, England–France and Israel–Germany all ended in draws. ^{[27] [28]}

Round 7

The top pairing in round 7 saw Azerbaijan and Poland draw on all boards. The United States defeated 18th-seeded Croatia 3–1 to join Azerbaijan and Poland on 13/14. Wesley So and Sam Shankland won with white, and Caruana and Nakamura recorded draws with black. Armenia's 2½–1½ win over Belarus saw them rise to clear fourth with 12/14, as the China–Ukraine, Germany–Netherlands and Israel–Czech Republic matches were all drawn. ^[29]

Round 8

A sole leader was established for the first time in the tournament as the United States defeated Azerbaijan 2½–1½. Teimour Radjabov struck first on board 2, defeating So. This was followed by Nakamura being held by Arkadij Naiditsch to another draw. Caruana equalised the score by defeating Mamedyarov, then Shankland with black converted the point against Rauf Mamedov to give the victory to the United States. The Poland–Armenia match ended with four draws, with Duda holding well against Aronian on top board. India defeated the Czech Republic 2½–1½, with three draws and one decisive game. It was the same scenario in the Israel–England match, where Luke McShane scored against Maxim Rodshtein. Germany defeated Spain by 2½–1½, with Daniel Fridman improving his score to 6½/7 as he defeated Josep Manuel López Martínez  [ es ]. A 2½–1½ result was also seen in the France–Ukraine and China–Netherlands matches. ^[30]

Round 9

Poland defeated the United States 2½–1½ to take first place. So and Shankland were held to draws with white, while Nakamura lost to Piorun and Caruana missed a win in a rook and bishop versus rook endgame against Duda. China and Armenia recorded 2½–1½ victories over Azerbaijan and India, respectively, to stay in contention for gold. England defeated Norway 3–1 to reach 15/18 along with the United States, China and Armenia. ^[31]

Round 10

China inflicted Poland's first defeat in the Olympiad as Ding Liren and Li Chao recorded wins. The United States defeated Armenia 2½–1½ to join China on 17/20, thus setting up a US–China clash for the gold medal in the final round. Russia and France won against England and Croatia, respectively, to both move up to joint-third place with Poland. Azerbaijan suffered their third successive 2½–1½ loss, this time to Ukraine, leaving them on 13/20 and out of the running for a podium place. ^[32]

Round 11

The derby match of the last round was contested by China and the United States on the top table, which ended in a tie with four draws. Russia narrowly beat France 2½-1½ thanks to Ian Nepomniachtchi's win against Étienne Bacrot on the second board and equalised the number of match points of China and the United States on the top. The tie-break, however, determined that China to win the gold, United States the silver and Russia the bronze medal. On the other top tables, the matches India-Poland, Germany-Armenia and Ukraine-Czech Republic were all tied, while England crushed Kazakhstan 3½–½ to climb to the fifth position overall. ^{[3] [33]}

Final standings

Jorge Cori of Peru won the individual gold medal in the Open event.

China won the gold medal in the open event for the second time after they have previously claimed the title in 2014. They scored eight wins, two draws and one loss for a total of 18 match points. The same result was achieved by the United States and Russia, who had inferior tie-breakers and came up on the podium by winning the silver and bronze medal, respectively. ^[3] United States were on track to defending the title and were the sole leader after eight rounds, ^{[34] [35]} but their loss to Poland in the ninth round set them back from winning the gold. ^[36] Despite the slow start and implausible play, Russia finished the tournament with four consecutive victories to catch China and the United States, which was only enough for the third place because of the relatively weaker schedule. ^[37] Poland were the biggest surprise of the tournament. They scored minimal match victories against the two top seeds, Russia in the fourth and the United States in the ninth round, and topped the table as sole leader after nine rounds. ^[38] Their loss to China in the penultimate and tie with India in the ultimate round, however, placed them on the fourth place overall with 17 match points, which was only equaled by England who came on the fifth place at the end. ^[37] The only unbeaten team in the open event was Germany with five wins and six draws but this score earned them only the 13th place. ^[39] Teams that disappointed the most were Azerbaijan (the fourth seeds) who finished in 15th place, Israel in 39th place, and Netherlands in 40th place. ^[40]

Jorge Cori of Peru, playing on board three, was the best individual player in the open event by scoring 7½ out of 8 points (seven wins and one draw) with a rating performance of 2925. The other gold medalists include Ding Liren of China on board one who scored 5½ out of 8 points with a rating performance of 2873, Nguyễn Ngọc Trường Sơn of Vietnam on board two who scored 8½ out of 10 points with a rating performance of 2804, Daniel Fridman of Germany who scored 7½ out of 9 points with a rating performance of 2814, and Anton Korobov of Ukraine as reserve player who scored 6½ out of 8 points with a rating performance of 2773. ^[5]
