Magnus Carlsen of Norway has won the World Chess Championship for the third consecutive time after defeating challenger Sergey Karjakin of Russia.
Carlsen sealed victory following three weeks of play and a series of tiebreakers in New York.
Karjakin tied against Carlsen in 12 regular rounds but was beaten in the final phase of four quickfire games.
Organisers said the event was followed by about six million chess fans around the world.
Hundreds of spectators paid between $100 and $500 to watch the games at a former fish market in Manhattan, separated from the two grandmasters by soundproof glass.
After his victory, Carlsen's supporters greeted him by cheering and singing ‘Happy Birthday’, to mark his 26th birthday.
The prize of $1.1m (£879,000) is divided between the two players with the winner taking 60 per cent.
