Results
Championship match
The Championship match between Magnus Carlsen and Fabiano Caruana was held from 9 to 28 November 2018 in London, United Kingdom, at the Cochrane Theatre of The College in Holborn.
Match regulations
The match was organised in a best-of-12-games format. The time control for the games was 100 minutes for the first 40 moves, an additional 50 minutes added after the 40th move, and then an additional 15 minutes added after the 60th move, plus an additional 30 seconds per move starting from move 1. Players were not permitted to agree to a draw before Black's 30th move.
The tie-breaking method consisted of the following schedule of faster games played on the final day in the following order, as necessary: Best-of-four rapid games (25 minutes for each player with an increment of 10 seconds after each move). The player with the best score after four rapid games is the winner. The players are not required to record the moves. In the match, Carlsen immediately won three games in a row, securing the championship. If the rapid games had been tied 2–2, up to five mini-matches of best-of-two blitz games (5 minutes plus 3 seconds increment after each move) would have been played. The player with the best score in any two-game blitz match would be the winner. If the blitz matches had failed to produce a winner, one sudden death "Armageddon" game: White receives 5 minutes and Black receives 4 minutes. Both players receive an increment of 3 seconds starting from move 61. The player who wins the drawing of lots may choose the colour. In case of a draw, the player with the black pieces is declared the winner.
Prize fund
The prize fund was 1 million euros net of all applicable taxes. Had the match been decided in the classical portion it would have been divided 60% vs 40% between winner and loser. As the match went to a tiebreak the split was more even at 55% vs 45%.
Previous head-to-head record
Prior to the match, Caruana and Carlsen had played 33 games against each other at classical time controls, of which Carlsen won 10 and Caruana 5, with 18 draws. The most recent game, during the 2018 Sinquefield Cup tournament, resulted in a draw.
Alternative logo
The World Chess Federation also showcased an "alternative logo", which depicts two figures with overlapping legs holding a chessboard. The image received controversy for appearing provocative and even "sexy". When the head of World Chess, Ilya Merenzon, was asked to speak on the topic, he said that "it's about two people fighting", but later added that "it would be nice to bring a little bit of sexual appeal into chess".
Organisation and location
The match was held under the auspices of FIDE, the world chess federation, with the organisation rights belonging to Agon, its commercial partner. Following the previous championship match in 2016, the president of FIDE, Kirsan Ilyumzhinov, said that the next venue would be in London or somewhere in Asia. Japan, South Korea and Singapore all said they were prepared to host the match. In November 2017, London was revealed as the host.
The Chief arbiter was Stéphane Escafre from France, and deputy arbiter was Nana Alexandria from Georgia. The appeal committee was composed of International Grandmasters and was chaired by Alexander Beliavsky (Slovenia) with Nigel Short (England) and Jóhann Hjartarson (Iceland) also present. The FIDE Supervisor was Ashot Vardapetyan, an International Arbiter from Armenia.
