Germany's Elisabeth Esterl and Italian Veronica Zorzi lead the European Ladies Tour's Raiffeisenbank Prague Masters after opening rounds of 66.
At six under par, the pair are two in front of England's Melissa Reid and South Africans Connie Chen and Lee-Anne Pace, while Reid's Solheim Cup team-mate Laura Davies - now 48 - is in a tie for sixth, one shot further back.
Zorzi went to the turn in just 30 with four birdies and an eagle at the long ninth, where she struck a five-iron to four feet.
"There are many par fives (four in all) and I'm a long hitter, so for me it's good," she said.
Esterl, also a two-time winner on the circuit, turned in 32 and then eagled the 470-yard 12th. "I've been struggling for a while, so it feels really, really good," she said.
