The 37-year-old Chawrasia, winner of three Asian Tour titles, two of which were also co-sanctioned by European Tour, carded 67 that included six birdies and two bogeys.
As for the other Indians who made the cut, Chiragh Kumar (70) was tied 15th, down from overnight tied 13th while Khalin Joshi (75) dropped to 40th from 18th and Rashid Khan (74) went down from 33rd to 45th.
Japan's Akinori Tani, a seasoned player at 39, took the lead with a seven-under 64 and at 11-under, he is three clear of his nearest rival, Prayad Marksaeng (71).
Chawrasia, who is recovering from a shoulder niggle, said, "I have been hitting the ball well and I am looking forward to the final day. There are a lot of good and in-form players in the Top-5 and they can all contend despite the leader being at 11-under."

On his game in the third round, he said, "I played very good today, to be honest. I putted well but I am not hitting the ball as good. It's a little bit wet out there due to the rain earlier but it was not as tough compared to the first two rounds. It wasn't really windy. The course is a little bit soft today. I have been playing good this week."
"I hope I can continue to play like how I did in the last three rounds tomorrow. I will stick to the same mindset tomorrow and will see how it goes. I almost eagled the first hole as I hit my second shot to about one-foot from the pin and that got me off to a good start. I also had a 20-feet putt for birdie on the fifth hole which was one of the notable birdies for me today.
"It (the game) is coming around. After the Hero Indian Open, when I finished second, I did not play much as I missed a few events for various factors including a small injury problem, but now things are falling in place," he said.
Tani put himself in prime position for a breakthrough victory when he charged into a three-shot lead after signing for a sensational seven-under-par 64 in the penultimate round.
