A second-round score of 67 has given SSP Chawrasia a one-shot advantage at the top of the Indian Open leaderboard.
Chawrasia was one of five players to share the lead after Thursday's play, but the world number 204 was able to build on his opening round with a faultless display that included four birdies.
Bangladesh player Siddikur Rahman sits in second place after a 68, while Chapchai Nirat and Joakim Lagergren lie three shots further adrift in a tie for third place.
Indian number one Anirban Lahiri is in a share of seventh position, while Miguel Angel Jimenez is down in 18th spot after only recording a level-par round on Friday.
