Simon Wakefield maintained his position at the front of the field after a second round 67 in the Rolex Trophy in Geneva.
The 27 year old is on 12 under par 132, a shot clear of two more Englishmen, Andrew Marshall and Stuart Little, with Denmark's Mads Vibe-Hastrup in fourth place on 134.
Wakefield, who shared the lead overnight with Vibe-Hastrup after opening 65s, was out in 32 with four birdies, and collected two more coming home, while
also dropping his only shot at the short 11th.
Stoke-based Wakefield has yet to win a Challenge Tour title, his best finish being tied 3rd in this year's NCC Open in Sweden. But if he can maintain this form he could join the list of champions come Sunday.
Marshall, from Norfolk, another seeking a maiden Challenge Tour title, and Gloucestershire left-hander Little, winner of the Rolex seven years ago, maintained their pursuit of Wakefield with 67s of their own.
But Vibe-Hastrup dropped back with 69, while Manchester-based Grant Hamerton carded the lowest score of the day, a seven-birdie 65, which hoisted him
into joint fifth place on 136 with Switzerland's Andre Bossert, Wolfgang Huget from Germany, and top-ranked Mark Foster.
The day began with England Paul Dwyer withdrawing with a back injury and ended with Sebastien Delagrange from France taking to his sick bed with a fever after
shooting an uncharacteristic 81 for 150.
There will be a cut after tomorrow's third round with the leading 18 players and ties going forward to Sunday's final round.
