Teen chess sensation R Praggnanandhaa's mother, R Nagalakshmi said on Friday she was elated to see her son seal a berth in the Candidates Tournament, adding the 18-year-old has a "long way to go" in the sport. The Candidates is the final contest to determine the challenger who will take on the incumbent world champion. Grandmaster Praggnanandhaa's dream run in the FIDE World Cup at Baku was ended on Thursday by world No. 1 Magnus Carlsen, who beat him 1.5-0.5 in the tie-break after the classical games ended in a stalemate. Praggnanandhaa became only the second player from the country after Viswanathan Anand -- and the youngest -- to play in the FIDE World Cup final.
