Thailand's Thongchai Jaidee tops the leaderboard heading into Sunday's final round of the 100th Open de France after shooting a three-under round of 68 at Le Golf National in Paris.
Jaidee had started the day as joint-leader alongside Rory McIlroy and Wang Jeunghun, but carded the only bogey-free round of the day to move two shots clear of his rivals.
The 46-year-old was understandably delighted with his performance which puts him within sight of an eighth career European Tour victory.
"I had a good game plan today," he said.
"I talked all the way around with my caddy and hit a lot of fairways.
"I played very positively today; trying to hit the greens and make a putt and everything worked well.
"I'll be trying the same game plan tomorrow and I'm really looking forward to it."
Wang, meanwhile, undid his fine work on the front nine with three bogeys on his way home, while McIlroy recovered from a poor start to birdie four of the last six holes and record a round of 70.
The Northern Irishman, however, admitted being frustrated by his lack of consistency.
"You saw two ends of the spectrum there," he said.
"There was the front nine where there was nothing fluid at all about what I was doing and then the back nine when I started to get some confidence and it went the opposite way, the best way it could.
"I guess it just shows a little bit of the fragile state of my game at the minute.
"The good's really good and the bad, it's pretty bad."
Wang and McIlroy are tied for second on six under, while defending champion Bernd Wiesberger of Austria is a shot further back and Martin Kaymer is one of five players sharing fifth place on three under.
