Victor Dubuisson held a two-shot lead at the end of the opening day of the Ballantine's Championship in Icheon, South Korea.
The Frenchman recovered from a double bogey on the par-four fourth to mix eight birdies with two bogeys in a round of 68.
That left Dubuisson on four under, two ahead of a group of five players which includes English pair Paul Casey and Mark Foster.
Casey picked up four shots with bogeys at the ninth and 11th holes, while Foster also had four birdies and two dropped shots to card 70.
Scotland's Richie Ramsey had a double bogey on the fifth, but sank five birdies to lie on two under, with Welshman Jamie Donaldson on the same mark after dropping a shot on the 18th.
Local favourite Jung Ji-ho completed the group.
Eleven players were tied for seventh on one under, among them Oliver Fisher and Ross Fisher of England, and Irishman Paul McGinley.
Windy conditions made life difficult for many of the competitors, but Dubuisson was more than satisfied with his efforts for the round.
"Very pleased with playing four under today," he told the European Tour website.
"My putting was really, really good today and I think it's the only way to achieve good scoring in these conditions.
"On the third hole the wind was from the left, and so on the fourth tee I thought the wind was going to be sort of left to right, but the wind was turning all the time.
"The wind just turned right to left and it went into the water. So I was not really upset after this double bogey because I didn't hit a bad shot.
"I did my best to get back my concentration, and I made two birdies, good putts on five and six, and that was the good turn today."
Casey, who only recently returned to playing following a shoulder injury, believes he can challenge for the title if he finds some consistency.
"I know if I play the golf I'm capable of, I've got a very good chance to win," said the Englishman.
"The way I played today, I need to keep that form going because there's a long way to go."
