Chess grandmasters' battle for world championship title ends after 12-match stalemate

Norwegian grandmaster Magnus Carlsen on Wednesday defended his world chess championship title after he defeated United States challenger Fabiano Caruana 3-0 in rapid tiebreaker games today in London.

After their three-week match ended in 12 draws, Mr Carlsen wrapped up the victory quickly with three straight wins to build an unassailable lead in the best-of-four rapid format.

The tiebreakers were played with 25 minutes for each player per game, while the 12 previous classical-style games lasted up to seven hours each.

Every single one of their 12 classical games ended in a draw, which had made the match between Mr Carlsen and Mr Caruana the first title contest in which no decisive results were managed in the competition's official 132-year history.

It's the third time Mr Carlsen, 27, has successfully defended his title after the Thor of Chess won it from Viswanathan Anand of India in 2013.

Mr Caruana, 26, failed in his bid to become the first American since Bobby Fischer in 1972 to become the world chess champion.

Mr Carlsen pockets NZ$910,637 for the win, while Mr Caruana gets NZ$745,209.
