The two-time European Tour winner, Chawrasia, who was defeated in a play-off last year, made a valiant effort to make early claim to the crown as a double bogey was the only blemish in an otherwise brilliant round that included seven birdies at the tricky Delhi Golf Club (DGC) course.
The 44-year-old Sanjay from Lucknow, who has seven title in the domestic circuit and finished 31st on the PGTI's Rolex Ranking last year, blasted eight birdies and three bogeys in the opening round.
Thailand's Prom Meesawat, Spaniards Jorge Campillo and Nacho Elvira fired a six-under 66 to trail Daniel by one-shot at the USD 1.66 million event sanctioned by the Asian Tour and the European Tour.
Unheralded Honey Baisoya, a 19-year-old golfer from Delhi, who finished 21st on the PGTI's Rolex Ranking last year, also brought home a 68 to grab a share of the fourth spot.
Former PGA Tour winner, Arjun Atwal (70), three-time Major champion Padraig Harrington (71) and six-time winner at the Asian Tour, Jeev Milkha Singh (72) were further down the leaderboard.
