But the day's honours were to American Peter Uihlein, who produced a scintillating eight-under 64 with nine birdies and one bogey to take a one-shot first round lead at Black Mountain Golf Club.
Chawrasia, Chiragh and Himmat were tied 14th, while Arjun Atwal was Tied-27th at three-under 68. Shiv Kapur and Rashid Khan opened the week with 70 each in Tied 41st, but Rahil Gangjee (72) in Tied-80th and Gaganjeet Bhullar (73) and Jeev Milkha Singh (73) needed solid second round scores to ensure weekend action.
Chawrasia said, "It was a good round, I hit it well and my putting was also good. Overall I played good today. I think it was windier in the afternoon and much tougher than the morning session. That was the difference. I'm hitting it really good and made a few putts.
"I don't think it's a long hitters' course. It's long but a few holes are also short. It's got a good mix of holes. I've played here every year and I always play well. I don't finish on low numbers but I am normally good around here. I like this course."
