England's Samantha Head carded a six-under-par 66 - 10 shots better than her first round - to leap into contention in the Vediorbis Open de France.
The Bedford-based 35-year-old was bogey-free around Le Golf D'Arras as she moved into a share of sixth on two under.
However, that was seven strokes behind Italy's Stefania Croce, who maintained her overnight lead by adding a 68 to her opening 67.
"I didn't play very well yesterday and after the round I slept for a couple of hours in the hotel here and then I hit some balls and worked on my game," said Head, whose round was the lowest of the tournament and lifted her from joint 86th.
"I knew the greens would be quite bobbly this afternoon and the only thing you can do when there have been lots of people on the greens is just trust your stroke.
"I'm just going to do the same tomorrow, trust myself and enjoy it.
"I'm starting to realise that it doesn't really matter what preparation you put in, if it's your day, it's your day and today it was."
Compatriot Felicity Johnson, from Harborne near Birmingham, carded a 72 to join Head in sixth.
Denmark's Iben Tinning won a car for a hole in one at the 14th on the way to a round of 69 and five under for the tournament.
