Kapur was third overnight and moved to tied second. He along with Australia's Wade Ormsby (66) have one victory each on the region's premier Tour and share the second place at the storied championship after Manley signed for a 66 to take his place atop the leaderboard with a three-day total of 10-under 200 at the Hong Kong Golf Club.
Among other Indians, Jyoti Randhawa (66) and Anirban Lahiri (67) moved to tied 15th at five-under 208, while Himmat Rai (68) was tied 29th alongside SSP Chowrasia (70) at three-under 210. Sujjan Singh (73) slipped to 66th at two-over 212.
Kapur gave the crowd at the Hong Kong Golf Club a reminder of his talent when he stormed his way back to the top with a flawless 66.
As he stands on the verge of another victory at the Hong Kong Open, which is celebrating its 55th anniversary, Kapur is confident he can maintain his good form and return to the winner's circle again.
"The key is to stay patient and it showed when I was rewarded with my birdies. If I can continue to keep the mistakes off the card, I stand a good chance," said Kapur, who claimed his maiden Asian Tour title in Thailand during his rookie year in 2005.
