Australian Hannah Green is on her own in 3rd place and five shots from Iturrius's lead.
With the outer edges of Cyclone Oma sweeping across the outstanding and picturesque Bonville layout, Iturrius was the only player to break 70 on day two and one of a very few to break par in the gusty winds which made club selection on a golf course surrounded by tall and mature vegetation particularly difficult.
No bogeys in 36 holes is almost impossible to comprehend given the demanding conditions, but Iturrius is an aggressive player who backed herself through the round.
Iturrios, who finished T34 at this event last year, said she was feeling confident in her game after making some swing changes recently.
“In the off-season, I changed my swing a bit to hit better low shots,” she said.
“So that’s helped a lot here because of the wind and rain.
“But I’m so comfortable with my game right now, let’s see what happens. 36 holes left.”
“I missed some putts but I made some good saves for par as well, so I’m very happy.”
19 year-old amateur Choi has done remarkably well after taking a two shot lead into day two and then hold on to be in 2nd place and although four behind the lead she will have the chance to play with the leader tomorrow.
After a shaky start the Concord Golf Club member regathered in the middle of her round only to drop three shots over the closing stages but she is still very much in contention for tomorrow.
Green was rock solid with a round of even par 72 to follow her opening 69 and as a three time winner on the Symetra Tour in the US and one of the more impressive rookies on the LPGA Tour in 2017 she must be considered a real chance to take the title.
The cut at the halfway mark fell at 7 over with 70 players to play the final 36 holes.
