SSP Chawrasia extended his lead to three shots as the third round of the UBS Hong Kong Open got under way in Fanling.
The Indian had led by five at one stage on day two but came into the weekend with a two-shot advantage as he looks for a first European Tour win outside of his homeland.
Swede Alexander Björk cut the lead to one after a flying start but he bogeyed the fourth, with Chawrasia making a first birdie of the day on the third to get to ten under at Hong Kong Golf Club.
Thomas Aiken, Rafa Cabrera Bello and Chris Hanson were alongside Björk at seven under.
The group at five under quickly started to expand, with the majority of players taking advantage of the par five third, and Cabrera Bello, Tommy Fleetwood and Justin Rose were among those to move four off the lead.
Last season's runner-up then rolled a slippery eight-footer down the hill on the eighth and the Spaniard was six under.
Englishman Hanson hit a smart approach into the seventh to add to gains on the first, third and fourth, and Björk birdied the first to also sit three off the lead.
Björk made it a birdie-birdie start as he put his tee-shot to tap-in range on the second and Hanson put his close on the eighth to join him at seven under, with Aiken saving par on the first after a smart up-and-down.
Cabrera Bello had been flying but a bogey on the ninth stalled his momentum as he turned in 32.
South African Aiken was looking shaky in the early stages but produced another excellent up-and-down on the second to stay two back.
Cabrera Bello bounced back brilliantly as he holed his second on the tenth for an eagle but he could not keep pace with Björk who became the latest man to capitalise on the third and moved to eight under.
Chawrasia was forced to lay up on the par five but it made no difference as the 39 year old made his birdie to get into double-figures, with Björk bogeying the fourth to make it a three-shot lead.
Thomas Detry, Wade Ormsby and Poom Saksansin were then all at six under.
