MOSCOW (Sputnik) — The tie-break, consisting of four games, took place on Wednesday in New York. Carlsen won the third and fourth games, thus beating Karjakin with an overall score of 3 to 1.
Karjakin said at a press conference after the Wednesday tie-break that he was "completely not ready" for the rapid-game format and made a lot of mistakes that Carlsen used to secure his victory.
During the 12 main games that Carlsen and Karjakin played on November 11-29, no winner emerged.
Carlsen first won the title of the world chess champion in 2013 and then successfully defended it the next year.
This year, the world chess championship prize is $1.1 million with the winner getting 60 percent of the monetary award.
