Magnus Carlsen’s recent struggles against India’s elite young grandmasters continued on Thursday as Arjun Erigaisi delivered a major upset at the FIDE World Rapid and Blitz Team Championships in Hong Kong.Just weeks after suffering consecutive defeats against R Praggnanandhaa at Norway Chess, the world No. 1 found himself on the wrong side of another result against an Indian opponent. This time, it was Arjun who emerged victorious, defeating Carlsen in Round 6 while representing Team MGD1.Playing with the black pieces, Arjun capitalised on a costly late mistake from the Norwegian superstar to secure the win in just 30 moves. The encounter began with a Reti Opening before transposing into the Three Knights Variation of the Queen’s Gambit Declined.The game itself was far from flawless. Both players found themselves under pressure and committed inaccuracies along the way. Arjun appeared to hand Carlsen an opportunity when he misplaced his rook with 26…Rd8, but the world champion was unable to take advantage.Instead, the decisive error arrived four moves later. Carlsen’s rook blunder allowed Arjun to seize control of the position, and the Indian grandmaster quickly converted the advantage. A queen capture on f3 (Qxf3) left Carlsen with no viable defence, forcing the Norwegian to resign.Time management also played a significant role in the closing stages. While Arjun still had nearly a minute remaining on his clock, Carlsen was operating with just 12 seconds, adding further pressure during the critical moments of the contest.The victory proved crucial in the overall team result as Team MGD1 edged WR Chess by 3.5-2.5. Aryan Abhijeet Shah also contributed an important win for MGD1 by defeating Wadim Rosenstein.WR Chess managed only one victory in the round, with Fabiano Caruana overcoming Abhimanyu Puranik.Following six rounds, Team MGD1 occupy second place in the standings with 13 points. They trail Dragon Chilling, the table-toppers led by former world champion Ding Liren of China. WR Chess, meanwhile, sit 12th with 10 points.Carlsen entered the event as the reigning world champion in both rapid and blitz chess. Arjun, meanwhile, continues to establish himself among the game’s elite after claiming bronze medals in both formats at last year’s World Championships in Doha.The result further underlined the growing influence of India’s new generation of grandmasters, with Arjun adding his name to a list of Indian players who have recently troubled the world’s top-ranked player on the biggest stages.
