18-year-old chess prodigy R Praggnanandhaa has finished as runner-up in the FIDE Chess World Cup held at Baku, Azerbaijan. He held world No 1 Magnus Carlsen to two consecutive draws in classical chess. The match then went to a tie-break, where Carlsen won 1.5-0.5. This is the first time since V Anand that an Indian has reached the final of the Chess World Cup, and Praggnanandhaa is the third youngest player to achieve this feat. What does this achievement mean for India? How do we rate his performance in this tournament? What is it that separates Carlsen from the rest of the field?
