Home favourite Thomas Bjorn finished round one of the Made in Denmark championship as co-leader on five-under-par.
Bjorn shot an opening-day 66 in his homeland to share the lead with Chilean Felipe Aguilar and Bradley Dredge of Wales heading into Friday.
The trio are followed by another Dane in Thorbjorn Olesen, who sits three shots behind after carding a 69 in the inaugural tournament in Aalborg.
There are no fewer than six players sitting on one-under-par, with Ireland's Peter Lawrie and Englishman Andrew Marshall among them.
