Edoardo Molinari shot his second straight 6-under 66 and earned a two-shot lead Friday after two rounds of the Czech Masters.
Tied for fourth and two strokes off the lead overnight, the Italian surged with six birdies for his second bogey-free round and a 12-under 132 total at the Albatross Golf Resort near Prague.
"At the moment, I'm very comfortable, I'm enjoying playing golf," Molinari said. "I've been going through a tough few years, so at the minute I'm just really enjoying myself on the golf course."
Three straight birdies on the final three holes gave 2015 Czech Masters champion Thomas Pieters of Belgium a bogey-free round of 5-under 67 and sole possession of second at 134.
Defending champion Andrea Pavan of Italy was among seven golfers tied for seventh after posting 68.
Three-time major champion Padraig Harrington was on 141 after a 68.
