An opening birdie saw Thomas Pieters extend his lead to two shots early on day four of the D+D Real Czech Masters.
Albatross Golf Resort has been a happy hunting ground for the Belgian, who tasted victory at the 2015 edition before coming second behind Paul Peterson the following year.
And he has enjoyed further success here so far this week, posting rounds of 67, 67 and 66 on Thursday, Friday and Saturday respectively to head into the final round with a one shot lead.
The big hitting Belgian rolled in his 18 foot birdie putt at the long first to jump to 17 under par before safely parring his next two holes as the wind began to blow in Prague.
Defending champion Andrea Pavan showed he was not ready to relinquish the trophy as he made six birdies in his first ten holes to reach 15 under and move up to second place.
