Four birdies in five holes saw Darren Beck move to 12 under par and into the lead at the Avantha Masters midway through the third round at DLF Golf and Country Club.
Starting the day in a tie for fourth place, two strokes off the lead, the Australian quickly made a move with three birdies and a bogey in his opening four holes.
Beck then picked up another shot at the sixth to reach the turn in 33, to be one stroke ahead of the chasing group of Barry Lane, Andrew Dodt, David Drysdale and Tetsuji Hiratsuka.
Veteran Lane, who at 49 is looking to become the oldest winner on The European Tour, remained well in contention after two birdies and a bogey saw him reach the turn on one under for the day.
Dodt began his third round in blistering fashion, the Australian opening with three consecutive birdies before a double bogey six at the fifth halted his momentum. However, he bounced back by picking up another shot at the eighth to reach the turn in 34.
Hiratsuka, who set a course record of 62 in the second round, was producing a more pedestrian effort as two birdies saw the Japanese golfer move to 11 under through ten holes, while Drysdale birdied the tenth to join him.
Chan Yin-shin, who led after the second round, had fallen to ten under after two bogeys were offset by only one birdie alongside Indian Rahil Gangjee.
