Ding Liren became the first male world chess champion from China in April 2023. He took the title after Magnus Carlsen declined to defend it — a circumstance that has been used to qualify his achievement, but only by people who have not watched the match. Ding’s 2023 victory over Ian Nepomniachtchi was a fifteen-day contest of resilience that produced some of the most dramatic chess of the modern era. He has paid for it in the two years since.

Early years

Ding was born in Wenzhou, a coastal city in southeast China. He learned chess at four from his father, a doctor and amateur player. The Chinese chess infrastructure of the late 1990s was thin — far thinner than the Soviet or Western European equivalents — and Ding’s development came largely through provincial tournaments and self-study.

He earned the International Master title at fourteen and the grandmaster title at sixteen years and ten months. He won the Chinese Championship for the first time in 2009 at age 16. He won it again in 2011 and 2012, becoming the most accomplished Chinese player of his generation.

His international breakthrough came in 2015 and 2016, when he won several major events including the Chinese Chess League MVP awards and a strong finish at the World Cup. By 2017 he was in the world top 10.

The 2017–18 streak

Between August 2017 and November 2018, Ding played 100 consecutive classical games without losing. The streak crossed three major tournaments — Sinquefield Cup, World Cup, Wijk aan Zee — and was the longest unbeaten streak in elite chess history until Magnus Carlsen surpassed it in 2020.

The streak elevated Ding’s profile internationally. He reached his peak rating of 2816 in November 2018, briefly the world No. 2. He qualified for the 2018 World Cup final, losing to Magnus Carlsen, and for the 2020-21 Candidates Tournament, where he finished second to Ian Nepomniachtchi.

The 2023 Championship

The path to Ding’s title was complicated. Magnus Carlsen — the reigning champion — announced in July 2022 that he would not defend the title against the 2022 Candidates winner (Nepomniachtchi). FIDE arranged for the 2023 match to be played between Nepomniachtchi and the second-place finisher from the 2022 Candidates — Ding Liren.

The match was held in Astana, Kazakhstan, from April 9 to April 30, 2023. The fourteen-classical-game format ended 7–7. Tiebreaks began. Ding won the rapid playoff 2.5–1.5, securing the title in the fourth rapid game.

The match’s defining feature was its volatility. Three classical decisive games for Nepomniachtchi, three for Ding. Two of Ding’s wins came after positions where he had been demonstrably worse. His preparation in the Spanish (the Berlin Defense as Black, multiple Anti-Marshall systems as White) was deeply researched but never decisive — the wins came from middlegame and endgame play under pressure that exceeded what most players manage.

The difficult defense

Ding’s reign has been the most difficult in modern history. He played little chess in 2023 after winning the title, citing health and personal reasons. His rating dropped from 2780 to the 2730s over the following twelve months — an unusually large drop for a reigning world champion.

The 2024 World Championship match in Singapore, against Gukesh Dommaraju, was held in November-December 2024. Ding lost 7.5–6.5. He did not play poorly in any single game — only one of his classical losses involved a clear blunder — but he did not play with the intensity that wins championship matches. He has spoken since about the toll of the title.

He has continued to play in selected events but has not returned to the top 10 rating list as of 2025.

Playing style

Ding’s style is universal in the modern grandmaster sense: he plays both colors of any opening, calculates accurately, and converts most positions where he has an advantage. His distinguishing feature, when he is at his best, is resilience. He plays positions that look lost and finds resources. His World Championship 2023 match contained three or four games where he was assessed as worse before producing the win.

His opening preparation is broad rather than deep. He does not specialise in any single system as Caruana does in the Petrov or Carlsen does in the Najdorf. The breadth has advantages — he is harder to prepare against — and disadvantages: his games tend to be decided by middlegame play rather than home preparation.
