Arjun Erigaisi and Aditya Mittal in a seven-way lead
Only three games ended decisively among the top ten boards and Black won in all of them. IM Sayantan Das defeated GM Harsha Bharathakoti. IM Arghyadip Das, IM Sidhant Mohapatra and CM Prraneeth Vuppala drew with GM Jiri Stocek (CZE), GM Marc Narciso Dublan (ESP) and IM Nico Zwirs (NED) respectively.
Arjun Erigaisi - Aditya Mittal: 0.5-0.5
GM Arjun Erigaisi got himself a pleasant position in the middlegame, despite his opponent IM Aditya Mittal having a bishop pair.
19.Nb3 Qa4 20.fxe4 dxc4 21.d5 Bxg4 22.Qxc4 Qb5 23.Rc1 Be2 24.Qxc6 Rhe8 25.Nf3 Qxc6 26.Rxc6 Bd3+ 27.Ka1 Bxe4 and Black managed to free up the position which gave him a slight edge due to both bishop getting activated in the open position. Arjun eventually liquidated into a completely winning rook endgame.
The one thing that you should not do when you have two connected passed pawns in a rook ending is, push the rook pawn to the seventh rank without having a sure way to win as this results in a draw because Black has a lot of stalemate tricks and it becomes excruciatingly difficult to move the knight-pawn, in this case b-pawn to the desired square which can fetch you a full point. Arjun probably made this mistake under time scramble. Aditya capitalized on his opponent's mistake and the game ended in a draw in the next few moves.
Karthikeyan - Nikita: 0.5-0.5
Karthikeyan got himself a good position, however he was unable to capitalize on it against Nikita Meshkovs (LAT).
It is evident from the above diagram that White is in full control. After 26...Qg3, White needed to go 27.fxg6 hxg6 28.h5 and things could have turned out better than the game continuation. In the game both bishop and queen got exchanged in consecutive moves, White still had a better position which practically is not easy to convert into win.
Sethuraman - Karthik: 0.5-0.5
Sethuraman had a fantastic position against Karthik Venkataraman.
24...g6 creates dark square weakness for Black on the kingside. 25.Ng4 is an interesting way for White to exploit that. Find out why it is a good idea. The game continued 25.Be2 Ne4 and Black managed to defend the position.
