Midlander John Bickerton revealed a flash of inspiration on the putting green contributed to him holding the lead after the first round of the French Open.
The Droitwich golfer, who won his maiden European Tour title last October, fell just one short of the course record at Le Golf National but his eight-under-par 63 was good enough to give him a two-stroke lead over 2005 US Open champion Michael Campbell.
And it was all down to finding a "feeling" in practice on Wednesday.
"I just holed a lot of putts today and that was the difference," said the 36-year-old, who won the Open de Canarias eight months ago and lost a play-off to Niclas Fasth at April's Andalucia Open.
"The last few weeks I have been struggling and when that happens the rest of your game tends to suffer as well.
"I did some hard work yesterday on the putting green and it paid off. When I played well in Spain I had a feeling and that clicked yesterday.
"I had the ball in a certain position - it felt like it was back in my stance and it made the difference.
"You get a feeling - it's ever so strange - like you've done it before. You are on the range or the putting green and something clicks and you think 'remember that'. That was the feeling I had yesterday."
It certainly worked as, starting on the back nine, Bickerton had three birdies in a row from the 11th with his longest putt being just 15 feet to turn in 32.
At the 563-yard third he was in trouble off the tee and had to chip out but he then holed a long birdie putt after hitting a five iron to 30 feet.
He picked up more shots at his next two holes, one from 25 feet and another from 12, before he closed with back-to-back birdies, signing off in style at the last with a 20-footer.
For New Zealander Campbell, it was a change of putter which did the trick for him.
Among his seven birdies - he bogeyed his opening hole - were two putts of 25 feet, one of 15 with the remainder all coming from inside ten feet.
"I changed putters for the first time in probably two years. The putter I used for the US Open and the World Match Play (which he also won last year) is being rested," said Campbell.
"The one thing that has really bothered me the last c ouple o f months has b e e n m y putting and today I finally saw something. I hit 17 greens today and had 30 putts. It was nice to see the ball go in the hole from 20 feet away."
Sweden's Joakim Back-strom did briefly reach eight-under himself after 13 holes but three successive bogeys from the 15th saw him finish with a five-under-par 66.
Ryder Cup-chasing Paul Broadhurst and Hereford's David Park were among a group on three-under. Broadhurst, pushing for a place in European team 15 years after his last appearance, birdied the water-guarded 18th as his fourth birdie but dropped a shot at the par-four 15th, while Park also recorded four birdies and a bogey at the 17th.
Steve Webster will will looking to improve after a one-over 72, especially after a double-bogey at the 18th which proved costly after three birdies and two bogeys.
European No 1 David Howell had a quadruple-bogey eight at the 18th in a seven-over 78 while Ian Poulter had a 68. Seve Ballesteros, a four-time winner of the French Open and making another comeback on the European Tour, carded a ten-over 81.
