On what turned out to be an easy day for the top seed, Gupta employed his pet Grunfeld defense as black and Lalith Babu went for a variation favoured by Vladimir Kramnik some time back. As it turned out in the middle game, things did not go Babu's way as he missed out on a tactical trick and lost a pawn.
There was compensation as the game was still around the boundaries of a draw but Babu again faltered and entered a worse endgame after which it was a long grind and Gupta made no mistakes to maintain a clean slate.
With Gupta on six points and Sengupta on 5.5, a pack of 16-players are sharing the third spot with five points apiece. Prominent among them are Grandmaster Ziaur Rahman of Bangladesh and Indian GMs Sahaj Grover, Deepan Chakkravarthy and Abhijeet Kunte.
Among the norm seekers, Himanshu Sharma remained on course for his final Grandmaster norm holding Rahman to draw while Arghyadip Das held Sahaj Grover to a draw.
In the women's section Padmini Rout put it across Harsha Bharthakoti to take her tally up to five points.
