Joost Luiten of The Netherlands burst into the lead during the third round of the ISPS Handa Wales Open in difficult conditions at The Celtic Manor Resort.
And he was not the only Dutchman going well - Tim Sluiter moved into a share of second with overnight leader Ross Fisher.
England’s Lee Slattery moved back into a share of the lead and then put two balls in water on the third hole for a quadruple-bogey seven.
First-round leader Slattery resumed two behind compatriot Fisher and wasted little time drawing level.
Fisher, back on the course where he made his Ryder Cup debut two years ago, bogeyed the first after driving into the rough and Slattery then converted an 18 foot chance on the next.
But at the 189 yard third the Bankia Madrid Masters champion Slattery's tee shot rolled down the bank into the lake and then from the drop zone his next attempt spun back in.
From five under par and joint leader he dropped to one under and into a tie for ninth.
Slattery was four behind, but from Luiten as Fisher had gone over the green and after a good chip missed from four feet.
Iskandar Johor Open winner Luiten was six under for the day with only three to play after an eagle two at the 15th.
Sluiter and Fisher were one back, with Thai golfer Thongchai Jaidee, Spain’s Carlos del Moral and German Marcel Siem on three under.
Nineteen year old Italian Matteo Manassero had reached three under as well with five birdies in six holes from the fifth, but the two-time European Tour winner, who on Monday came through a play-off to qualify for the US Open, bogeyed the 499 yard 16th.
Fisher birdied the fifth and sixth to regain the lead, but promptly bogeyed the next two.
That handed top spot back to Luiten and when he two-putted the par five last for birdie he was round in a best-of-the-week 64 to set the clubhouse target at six under.
Jaidee quickly joined him, however, with birdies at the eighth and ninth, while Fisher was two back with Sluiter and Del Moral.
