Indian Grandmaster R Praggnanandhaa defeated Russia's Vladislav Artemiev in the 15th and final round of the preliminary phase of the Airthings Masters, an online rapid chess tournament, but missed out on qualifying for the quarterfinals. The 16-year-old started the final day of the preliminary rounds with a draw against German Vincent Keymer in round 13 before going down to Hans Mokko Niemann (USA) in the next. His stirring win over world champion Magnus Carlsen in the eighth round caused a flutter but up-and-down performances pegged Praggnanandhaa back.
