Jordan Smith has taken a two-shot lead into the weekend at the DP World Tour clash in Hamburg.
The 29-year-old Englishman hit back from an early bogey to register five birdies that carried him to six under par.
France's Victor Perez sits second after two rounds at four under, with Julien Brun, Joakim Lagergren and Niklas Norgaard Moller at three under par.
Chippenham-born Smith claimed his maiden DP World Tour title in 2017 at the same event, and now sits 13th in the tour rankings.
"I have really good memories of most of the holes around here," said Smith.
"Winning back then, even though it was five years ago, I still remember a lot of it.
"I'm looking forward to continuing the good stuff and seeing how the weekend goes."
Australia's Jason Scrivener shot one over in the second round to be tied eighth.
He is five behind the lead at one under.
