National Challengers 2017 Round 4: Mary Ann Gomes wins an instructive rook endgame

by Gopakumar Sudhakaran - 16/08/2017

Perfect scorers were chopped down from seventeen to just six in the fourth round of the 55th National Challengers. The round witnessed some nail-biting action: Mary Ann Gomes won the day with her instructive endgame against GM Deepan Chakravarthy; GM Abhijit Kunte squeezed a win out in a seemingly drawn endgame against Arjun Erigaisi; while players from team Railways showed no mercy beating down their own teammates on the top two boards. A report with pictures and games from Ahmedabad.

Six players including former National champion Abhijit Kunte of PSPB are leading with a perfect score after the fourth round of the ongoing National Challengers Chess Championship at Karnavati Club on Monday.

 

Pune based GM Abhijit Kunte has the company of Mary Ann Gomes, Sammed Jaykumar Shete of Maharashtra and Railway men Swapnil Dhopade, Himanshu Sharma and S. Nitin at top of the points table.

Playing with white pieces, Kunte defeated Asian Under-14 champion Arjun Erigaisi of Telangana with some brilliant endgame play

Abhijit Kunte did a ChessBase India show with IM Sagar Shah a few days ago in which he discusses his brilliant performance at the Olympiad in Istanbul in 2000. Have a look at one hour show and also some brilliant endgame play by the Pune grandmaster. His technique is really something to learn from.

In the all-railways encounters, GM Swapnil Dhopade and GM Himanshu Sharma defeated team mates CRG Krishna and Hemant Sharma respectively to maintain their clean slate.  IM S Nitin joined the leaders after beating Chakkravarthy Reddy while Jaykumar Shete received a walk over from ninth seeded M.S. Thejkumar, who later withdrew from the championship due to health issues.

Chess is a war over the board. And team railways showed their warriorhood. GM Swapnil Dhopade showed no mercy finishing off his round 4 opponent and teammate, IM CRG Krishna on board 1... 

...while GM Himanshu Sharma went all guns blazing against Hemant Sharma on the second board. Do enjoy the games below.
