Only two other Indians, defending champion Gaganjeet Bhullar and Rahil Gangjee made the cut and among those missing it was Anirban Lahiri.
Chiragh, who has been under weather for the past two days and has admittedly avoided practice to conserve energy, played steady and avoided mistakes. Starting on the tenth, he managed four birdied against one sole bogey on the eighth. Chiragh at seven-under 137 is two shots behind leader Thaworn Wiratchant, who roared back into form with a second round card of 67 after shooting 69 on first day.
"I just hope to continue my form. I'm going back to rest now because I don't have any energy to practice. My ankle is alright now but hopefully the pain won't come back," he said.
Bhullar succeeded in bringing himself back into the picture with a round of 69 that somewhat made up for his first round 73 and at two-under 142, he is tied ninth.
Rahil Gangjee (70-74) tripped on his second nine, the front side of the course, with three bogeys between second and seventh, but he is still tied 22nd as he was the third Indian to make the cut.
However, Abhinav Lohan (73-76), Himmat Rai (75-74), Anirban Lahiri (72-75) and Ajeetesh Sandhu (75-80) missed the cut.
