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 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. The prize of 1.1 million dollars is divided between the two players with the winner taking 60 per cent.
The last Russian to claim the title was Vladimir Kramnik in 2007.
The competition initially offered prize money of 600,000 euros ($637,000) for the winner, and 400,000 euros for the losers, but that was changed to 550,000 and 450,000 euros respectively because the battle went into extra time.
