Norway Chess is an annual closed chess tournament, typically taking place in the May to June time period every year. The first edition took place in the Stavanger area, Norway, from 7 May to 18 May 2013. The 2013 tournament had ten participants, including seven of the ten highest rated players in the world per the May 2013 FIDE World Rankings.[1] It was won by Sergey Karjakin, with Magnus Carlsen and Hikaru Nakamura tied for second place.[2] Norway Chess 2014 took place in mid-June 2015 and was a part of the inaugural Grand Chess Tour. The tournament has since decided to withdraw from the Grand Chess Tour.[3]
The 2013 tournament started with a blitz round played at the University of Stavanger on 7 May 2013. Rounds 1–8 were played at Hotel Residence, Sandnes (rounds 1–3, 5–6, 8), at Aarbakke factory in Bryne (round 4) and on the island Sør-Hidle in Strand (round 7).[5] The final round 9 was played in Stavanger Concert Hall on 18 May 2013. In addition to the super tournament, there was a local school tournament and a celebrity tournament. Partly parallel to the tournament, Stavanger Open NGP 2013 was arranged by Stavanger Chess Club from 8 to 12 May. Games were streamed live with Dirk Jan ten Geuzendam and Simen Agdestein as commentators.[6]
The tournament was arranged by the foundation Norway Chess, with economic support from local businesses and municipalities and the Rogaland county. The cost of the arrangement was predicted to be about 5 million Norwegian kroner (approximately 672,000 euro),[7] of which about half is for the prizes for the participants.[8] The organizers plan to make the tournament a yearly event.[8]
Vladimir Kramnik was originally among the expected participants, but in April 2013 it was announced that he had withdrawn and was replaced with Peter Svidler.[9]
Blitz tournament
On 7 May 2013, a blitz tournament was played to decide the play order for the main tournament.[10] According to regulations, the winner of the blitz tournament had the right to choose the number in the table by his own, and Sergey Karjakin chose to be fifth in the main tournament table.[11]
Second, third and fourth place were decided by tiebreakers: Carlsen on most games with black pieces; Anand with two victories with black against Nakamura's one victory.[10]
The places 3, 4, 7 and 8 were decided by tiebreakers: Karjakin on most games with black pieces, Kramnik with one victory with black against Caruana's zero victory.[18]
The tiebreakers were: most wins, direct encounter, Sonneborn-Berger system, extended Koya system.[27]
2016
The fourth Norway Chess Tournament took place from 18 to 30 April 2016 with a new title sponsor, Altibox.[28] The tournament withdrew from the Grand Chess Tour in early January 2016 citing differences on the future of chess supertournaments and tournament sponsorship.[29]
On 6 April, Karjakin decided not to play in the tournament.[31] His spot was taken by Li Chao.
Wild card qualifier
A qualifying tournament took place from 23 to 26 March 2016. It was a double round robin consisting of two stages: the first leg was played with a classical time control and 3–1–0 scoring system; the second leg was played with a rapid time control and 2–1–0 scoring system.[32][33] It was won by Nils Grandelius.
On 18 April 2016, a blitz tournament was conducted to determine the pairings in the tournament. The top 5 finishers in the blitz tournament earned an extra white game in the tournament.
The fifth Norway Chess tournament was held between 6–16 June 2017. The tournament involved all ten of the world's best players by rating (at the time of announcement) and had an average Elo rating of 2797. As a result, it was billed as the strongest chess tournament in history by Altibox, its sponsor.[36] However, by the time the tournament was held two players had dropped out of the top ten (Karjakin and Giri; their replacements Mamedyarov and Ding Liren did not play).[37] It is also not the tournament with the highest-ever rating average; the 2014 Zurich Chess Challenge and the 2014 Sinquefield Cup had average ratings of 2801 and 2802, respectively.[38]
Blitz tournament
On 5 June 2017, a Blitz tournament was conducted to determine the pairings in the tournament. The top 5 finishers in the blitz tournament earned an extra white game in the tournament. Magnus Carlsen, Hikaru Nakamura, Levon Aronian, Maxime Vachier-Lagrave and Vladimir Kramnik finished in the top 5 and earned their extra white game.
The blitz tournament was played on 27 May 2018. The winner of the blitz tournament chose his number in the main tournament. Number 2 got the highest available number, and number 3 the second highest, and so on.[41]
On 31 May 2018, Ding Liren fractured his hip bone in a bicycle accident and underwent surgery the next morning. It was announced on 2 June that Ding had withdrawn from the tournament. Due to him having played less than half the rounds, the three draws (against Nakamura, Vachier-Lagrave and Anand) that he had played in rounds 1–3 were discounted for tournament purposes, and counted only for rating purposes.[44]
The tournament regulations for the classical tournament were different than other tournaments. Players were awarded 2 points for a win, and 0 points for a loss. In the case of draws, the players would move on to an Armageddon game, with 10 minutes for White and 7 minutes for Black, with Black having draw odds. Players were awarded 1½ points for a draw and an Armageddon win, and ½ points for a draw and an Armageddon loss.[46][47]
The performance rating is based on classical games only. As with 2019, an Armageddon game was to follow if the main classical game ended in a draw. The points system was altered to award 3 points for a win, 0 points for a loss, 1½ for a draw and an Armageddon win and 1 for a draw and an Armageddon loss.
Seeding was based on a blitz tournament played before the classical event. A classical win was worth 3 points and a loss 0 points. If the classical game was drawn, an armageddon game was played, with the same colours as the classical game. The player who won the armageddon game received 1½ points and the loser 1 point.

In parallel with the open tournament, an inaugural women-only version will be held, with an equal prize fund given for the open and women's tournament.[54] A classical win is worth 3 points and a loss 0 points. If the classical game is drawn, an armageddon game (white with 10 minutes, black with 7 minutes) will be played, with the same colours as the classical game. The player who wins the armageddon game will receive 1½ points and the loser 1 point. The open section of the tournament was won by Magnus Carlsen, whilst Ju Wenjun won the women's section of the event.[55][56]
