Playing partners Matt Wallace and Finland's Sami Välimäki both started the day two shots behind the lead and went on to card 67s for a share of the lead at 16-under at the D+D Real Czech Masters.
"Three holes there in the middle that could have really derailed me in the past," said the Englishman. "I’d like to say a future Matt can deal with those sorts of things quite well. I’m dealing with them pretty good now. I still feel like I’m going to be in contention, got through that sticky patch and managed to finish strong.
"There have been a few winners up at the top of this leaderboard this week but I’d like to say I think I’ve got the most. I can get the job done, so I know that. I know what I’m going to do now in preparation for tomorrow that gets me in the best mindset. I know that I can win, that’s the beauty of this game."
Dane Nicolai Højgaard lies on third place one shot back after a third-round 69.
The Netherlands' Wil Besseling also closed with a 67 for solo fourth place at 14-under one shot ahead of Germany's Nick Bachem (67) and Maximilian Schmitt (68) as well as England's Todd Clements (69), Japan's Ryo Hisatsune (69) and Paraguay's Fabrizio Zanotti (65).
