India's Rameshbabu Praggnanandhaa came back strongly from a game deficit to stun world champion Magnus Carlsen in tiebreaks in the seventh and final round thus finishing runner-up in the FTX Crypto Cup, the second major on the Champions Chess Tour.

Starting the round two points behind the Norwegian Carlsen, the 17-year-old Pragg was looking down and out after losing the third of the four rapid games. But Carlsen, who was steering the fourth game to a draw, blundered in the endgame and the Indian capitalised on it to take the match into blitz tiebreaks. In the four rapid games, Praggnanandhaa created a number of chances in the drawn first game, defended superbly in the second -- another draw --, went down in a tense third encounter before capitalising on Carlsen's mistake to win the fourth.
