A consolation for all chess fans: even the best sometimes blunder. In Round 5 of the Oslo Esport Cup, World Champion Magnus Carlsen blundered a whole rook against Jorden van Foreest, which cost him the game, the match, and the lead in the tournament. With two rounds to go, Praggnanandhaa, who won his match against Eric Hansen 2.5-0.5, is now again sole first with 12/15 and three points ahead of Carlsen who follows with 9.0/15. | Photos and pictures: Play Magnus Group
