Indian teenager Gukesh Dommaraju has become the youngest-ever world chess champion after beating defending champion China's Ding Liren in a dramatic turn on Thursday.
Dommaraju, 18, is four years younger than the former record-holder, Russian grandmaster Garry Kasparov, who was 22 when he won the title in 1985.
The Chennai prodigy has long been a superstar in the chess world, having attained the status of chess grandmaster at the age of 12.
But he was seen as the outside challenger going into the final round of the FIDE World Chess Championship, held in Singapore this year.
Playing on black, Dommaraju won the game after Ding, who had been in a solid position, made a fatal move that gave up his last powerful piece.
His blunder delivered victory to the 18-year-old, who until now had been ranked fifth in the world and second in his own country.
The 14-game World Championship competition had been closely watched by chess fans around the world this past fortnight.
