Gukesh Dommaraju — an 18-year-old from India — has become the youngest-ever world chess champion. That’s after beating defending champion Ding Liren, a 32-year-old from China.

Dommaraju comes from Chennai, in the state of Tamil Nadu. Saradha V, a BBC reporter in Chennai, explains how the city became India’s chess capital and how schools there are producing an impressive generation of young players.

Plus: Giovanni Sala, a Lecturer in Psychology at the University of Liverpool, explains how the Internet is helping chess players master the game more quickly than players did decades ago. He also describes the benefits that chess has for young people.
