In the Chennai Grand Masters 2026, M. Pranesh handed world champion D. Gukesh his second consecutive defeat, a stunning upset that reshapes the local standings. Pranesh’s victory came in 39 moves, reinforcing his rising status and highlighting the depth of India’s chess talent. The result tightened the top of the field as Nihal Sarin beat Arjun Erigaisi, leaving French GM Alireza Firouzja with sole leadership on 4 points in a round-robin event featuring eight grandmasters and a prize purse of ₹75,00,000. Gukesh’s loss followed a string of costly miscalculations, contributing to a slide in his form and rating as he sits near the bottom mid-tournament. The drama underscores the tournament’s narrative of intense competition among India’s young grandmasters, with Pranesh’s upset serving as a marquee moment in the event.
