2025 O2C Doeberl Cup - GM Mitrabha Guha wins

 The 2025 O2C Doeberl Cup has seen the top seed GM Mitrabha Guha finish in 1st place, with 7.5/9  He went through the tournament undefeated, and played the other 4 GM's in the field along the way. Interestingly, the top 5 places were all occupied by the 5 GM's in the tournament, with GM Das Sayantan in 2nd on 7/9, and GM's Zhao, Antonio and Stopa all tying for 3rd on 6.5.

The 59 player field was tougher than last year, with the the Premier being harder to qualify for. Despite this, Guha won when he needed to, and event though he only needed a draw in the final round, still pushed hard for a win (it was eventually drawn). His style suited the  shortened tournament format ( 9 rounds over 5 days), keeping his positions under control until his opponent made a mis-step. 

For winning this years event Guha collects $5000 first prize. Das picked up $3000 for 2nd, as well as a 33% share of the Fighting Fun, alongside Zhao and Stopa.

 Overall the tournament attracted 377 players across the 5 division, while the Saturday night blitz attracted 200 players across 2 sections. 

Reports on the other events to follow across the next few days

Usual blunder on my part, chessbase export of 0-0 needs to be changed to O-O
