After a rather easy draw with Nubairshah Sheikh in the third round, Gupta came up with outstanding performance on the fourth day that had double rounds.
In the morning, Grandmaster Niaz Murshed did not prove any match for the wily Indian while the peaceful intentions of GM Ankit Rajpara also received a jolt in the fifth round.
Grandmasters Swapnil Dhopade and Vaibhav Suri played out a draw on the top board and these two were joined by Gupta, Aravindh Chithambaram and Tejas Bakre in the lead on 4.5 points out of a possible five.
Gupta was up against the Fianchetto variation in the Grunfeld defense and chose a solid setup giving little away to Rajpara. The early phase of the game saw Gupta spurning an unconditional draw offer and the defending champion was in full flow on the queen side to hand Rajpara his first defeat in the event.
