ASTAN: China’s Ding Liren was crowned on Sunday as the 17th world chess champion in a tense match against Russian-born Ian Nepomniachtchi in Astana, Kazakhstan, in the last chapter of an odds-defying sequence of events. Thirty-year-old Ding won the rapid chess playoff by 2.5 points to 1.5, capitalizing on Nepomniachtchi’s mistakes in time trouble in the last of the shorter-format games, following the pair’s 7-7 tie in a psychological battle across 14 longer “classical” games. “One Ding to rule em all,” fellow grandmaster Anish Giri wrote on Twitter in honour of the new champion. Ding’s triumph means China holds both the men’s and women’s world titles, with current women’s champion Ju Wenjun set to defend her title against compatriot Lei Tingjie in July. Ding had leveled the score in the regular portion of the match with a dramatic win in game 12, despite several critical moments — including a purported leak of his own preparation. The Chinese grandmaster takes the crown from five-time world champion Magnus Carlsen of Norway, who defeated Nepomniachtchi in 2021 but announced in July he would not defend the title again this year.
