Indian teenager Gukesh Dommaraju capped a stunning ascent to the pinnacle of chess by dethroning China's Ding Liren to become the youngest ever world chess champion on Thursday in Singapore.

The 18-year-old from Chennai snatched the decisive victory from a dead-drawn position in the final game of their best-of-14-games showdown when Ding made one of the worst blunders in the 138-year history of world championship matchplay. The 32-year-old defending champion resigned moments later after a game that lasted 58 moves and just over four hours, sealing Gukesh's 7-6 win in the $2.5m match and rendering moot the widely expected prospect of tiebreaker matches on Friday afternoon.
