Alexander Levy and Eddie Pepperell shared the lead as the second day of the Sky Sports British Masters got under way at Walton Heath Golf Club.
Both men had signed for first rounds of 67 and home favourite Pepperell turned in 34 on the back nine in round two to get to seven under.
Frenchman Levy was alongside him after two birdies in his first five holes on a day of tough scoring in windy conditions.
Matt Wallace was at five under, a shot clear of Joakim Lagergren, Mike Lorenzo-Vera and Richard McEvoy, with all of those players not due out until the afternoon.
Pepperell and Levy both already have wins this season, with the former making the headlines on day one with a spectacular hole-in-one on the ninth.
Levy had a hole to complete after play was suspended due to darkness on Thursday night and he birdied the last to make it a four-way tie at the top at the end of round one.
Pepperell broke out of that group with a birdie on the 11th but Levy made a gain on the same hole before Pepperell holed an 18-foot left-to-righter on the 14th to get to seven under.
Tommy Fleetwood had started the day in a share of the lead but he made three bogeys in a row from the 11th to quickly find himself five shots back.
That was soon four as Pepperell made a first bogey of the day on the 15th and the lead was shared again.
Not for long, however, as Levy put his approach to the 14th to eight feet and the five-time European Tour winner was seven under.
Pepperell then hit back with an approach to six feet on the 18th and the duo were tied at the top.
American David Lipsky was one over after 11 holes to sit at three under alongside Scot David Drysdale and England's Ross Fisher, who were both level par for the day.
Fleetwood bogeyed the 17th to turn in 40 and sit at one under.
