GM M. Pranesh handed world champion D. Gukesh a second consecutive defeat at the Chennai Grand Masters 2026 on Tuesday, 22 July, while GM Nihal Sarin produced a brilliant rook sacrifice to eliminate compatriot Arjun Erigaisi from joint lead in the penultimate round of India's most prestigious classical chess tournament. The twin upsets have reshaped the title race at The Westin Chennai Velachery hotel, with French GM Alireza Firouzja now in sole command.

Firouzja Takes Sole Lead

Firouzja, who drew his Round 6 game against GM Nodirbek Abdusattorov, sits atop the standings with 4 points. Erigaisi and Abdusattorov are tied in joint second place on 3.5 points each, with two rounds remaining in the fourth edition of the tournament organised by MGD1. The event offers a prize purse of ₹75,00,000 along with valuable FIDE Circuit points.

Pranesh Punishes Gukesh's Calculation Errors

The round opened with a ceremonial first move by Narendra Kumar, Managing Trustee of Chola Foundation, and WGM Aarthie Ramaswamy. For much of the game, Gukesh appeared on course to end his losing run — but the world champion erred more than once in his calculations. Pranesh capitalised ruthlessly, converting the advantage to register his first win of the competition in 39 moves. Gukesh now sits at the foot of the table with just 1.5 points.

Nihal's Rook Sacrifice Ends Erigaisi's Title Hopes

The day's most dramatic game unfolded between Erigaisi and Nihal Sarin. Erigaisi needed only a draw to remain in joint lead with Firouzja, and for the majority of their 60-move encounter, that outcome appeared likely. A stunning rook sacrifice by Nihal, however, swung the game decisively in his favour, forcing Erigaisi's resignation and dropping him a full point off the lead. Nihal climbs to 3 points.

What to Watch in the Final Rounds

With Firouzja holding a half-point cushion, the critical clash in Round 7 is his head-to-head against Erigaisi — a must-win for the Indian if he is to reclaim a share of the lead. Meanwhile, Gukesh faces Niemann in what is now a pride-salvage mission. The final round will determine whether Firouzja clinches the title outright or whether the Indian contingent forces a dramatic finish at one of the country's most celebrated chess gatherings.
