Shiv Kapur staged a fine comeback on the front nine as he turned in a four-under for nine holes to move from two-over to two-under at the Abu Dhabi HSBC Golf Championship after the second round was delayed by early morning fog.
Kapur still has nine more holes to play in second round.
Kapur started from 10th and birdied the 10th, 13th, 14th and 17th to get to four-under and two-under through 27 holes.
Andy Sullivan fired a second consecutive 67 to set the target. The second round is unlikely to be completed because of the two hour 45 minute delay in the morning.
Sullivan book-ended his round with two three-birdie runs to get to ten under.
Overnight leader Bryson DeChambeau, looking to become just the fourth amateur winner in European Tour history, was one shot back after his opening 64 and he was one-under through nine holes.
In the tied third place was Joost Luiten, who added a 68 to his first round 69 and was seven-under.
Sullivan has good memories of his last visit to the Gulf states, when he pushed Rory McIlroy all the way at the season -ending DP World Tour Championship, Dubai.
The 28 year old finished eighth in last season's Race to Dubai after claiming three wins and arrived at Abu Dhabi Golf Club on the back of claiming three points out of three for Europe at last week's EURASIA CUP presented by DRB-HICOM.
He continued the theme of threes on Friday as he opened with three birdies from the tenth and, after dropping a shot on the 15th, he played a fantastic second shot from a fairway bunker on the first set up another gain.
