Shete, now five points adrift of the lead bunch that includes top seed GM Kravstiv Martyn of Ukraine, forced his rival to concede defeat in 41 moves after commencing with the king's pawn opening in the round seven clash.
GM Chanda (ELO 2571) opted for a Kingside Fianchetto response. On the 32nd move, Shete (ELO 2375) won a pawn and later on the 41st move won a piece by forking a bishop and rook.
Faced with a tough challenge, Chanda saw no option but to resign.
Top seed Martyn (ELO 2662) outplayed India's Rahul V S (ELO 2233) showing why he is among the top 100 players in the world.
Martyn then sacrificed his rook and attacked the king aggressively. Rahul, realising there is no way to save the game, accepted his defeat in 30 moves.
GM Amonatov Farrukh (ELO 2605) got the better of FM Erigaisi Arjun (ELO 2505) of India in 51 moves in another clash.
In the B Category (under 2000) final round, 12th seed Pavan BNB from Andhra - with 8.5 points - emerged victorious on the basis of his ranking.
