The world No 238 birdied four of the first six holes on her inward nine and ended the day with a one shot lead over Scotland's Kelsey MacDonald, Nanna Koerstz Madsen of Denmark, Finns Minea Blomqvist and Noora Tamminen - who had a hole-in-one at the 140-yard 11th - and Australia's Celina Yuan.
Anne van Dam of the Netherlands leads on 10 under after a bogey-free seven-under 65 at Emirates Golf Club.
England's Georgia Hall is in a three-way tie for third, one shot behind MacDonald, after a five-under 67.
Hall admitted she was suffering with jetlag and fatigue having travelled to Dubai immediately after securing her LPGA Tour card for next season at the Final Stage of Qualifying School, finishing the gruelling five-round event in a tie for seventh at Daytona Beach in Florida.
I did putt well today and I wanted to take advantage of the morning round, because the greens were in better condition and less wind, so I'm glad I did it.
The 27-year-old world number 521 made six birdies and two bogeys to move to outright second on eight under.
