Vincent Keymer conquers Quantbox Chennai Grand Masters with a 2917 performance, Arjun Erigaisi third

by Shahid Ahmed - 16/08/2025

Vincent Keymer (GER) finished Quantbox Chennai Grand Masters in style as he defeated Ray Robson (USA) to finish with an unbeaten 7/9. It was his fifth win of the tournament, finished a whopping two points ahead of the rest, performed at 2917 and gained 20.9 Elo rating points. The last round win also allowed Keymer to cross 2750 in the live ratings. He is now at 2750.9 to be exact and World no.10. Anish Giri (NED) scorched the reigning Dutch champion, Jorden van Foreest (NED) to score his first win of the tournament after eight draws. It was enough for him to secure second place. Arjun Erigaisi had a well contested draw against Karthikeyan Murali to finish third. The total prize fund was ₹1 Crore, for Masters it was ₹7500000. The top three prizes were ₹2500000, ₹1500000 and ₹1000000. Photos: Anmol Bhargav and Himank Ghosh

Pranesh clear first in Challengers, Adhiban remains undefeated

GM Pranesh M became the champion in the Challengers section as he hoped he would before the final round. The only thing that did not happen as he wanted was a win against IM Harshavardhan G B. The former Asian Junior champion and the first IM to take part in this tournament, defeated the eventual champion, Pranesh in the final round. GM Adhiban Baskaran showed his class in the final round by winning against GM Leon Luke Mendonca to finish second. The reigning National Rapid champion, GM Iniyan Pa finished his campaign with a win over GM Abhimanyu Puranik, still Abhimanyu managed to finish third. Adhiban is the only player to have remained undefeated in the Challengers section, reminding everyone once again why he crossed 2700 a little over a decade ago. The prize fund in the Challengers section was ₹2500000. The top three prizes are ₹700000, ₹400000 and ₹325000.

After eight draws, GM Anish Giri (NED, 2748) made his intentions clear that he wants to finish the tournament with a victory over the reigning Dutch champion, Jorden van Foreest (NED, 2697). 15...e5! was an inkling to that. What followed next is a wild battle 16.exd5 exd4 17.0-0-0 c3 18.Kb1 a5 Black did not waste any time in launching an attack, leaving White no time to launch an attack of his own.
