Rupam's first rating tournament triumph of the year
The top seed of the tournament and reigning Hooghly District 2025 Open champion, Rupam Mukherjee made a brilliant start scoring a triple hat-trick of wins. WCM Rajanya Datta was the sole player trailing him by a full point at 8/9. A draw would have sufficed for Rupam to become a clear champion. He still went for a maximum and defeated Somiddho Rajbanshi to become champion with a 100% score 10/10. Arhashirsha Biswas won against Rajanya to finish second. Satyam Prakash scored a full point versus Tanmoy Mondal to claim third place.
A total of 279 players took part from various parts of India.
