Thomas Bjorn and Stephen Gallacher are tied at the top at the halfway point of the European Masters at Crans Montana in Switzerland.
Bjorn looked set for the outright lead having moved clear of the field at 11-under, but contrived to bogey the last from the middle of the fairway to drop back alongside Gallacher at 10-under.
The duo are a stroke clear of a group of five players that includes Miguel Angel Jimenez who, like Bjorn, made a clumsy bogey at 18 to slip just off the 36-hole pace.
Jimenez - who is making his 25th consecutive appearance at the event - has been joined at nine-under by English trio Tommy Fleetwood, Danny Willett and Richard Finch and France's Victor Dubuisson.
Also within three shots of the top two on a packed and high-quality leaderboard are Paul Casey (eight-under) and Padraig Harrington and Richard Sterne (both seven-under).
Having posted a flawless 66 on Thursday, Bjorn produced another very solid round and looked set to go bogey-free once again before his blemish on 18 which was the result of a misjudged wedge and a rather heavy-handed chip.
The Dane made a total of six birdies and told Sky Sports afterwards: "I played better today than yesterday, although at the end it wasn't the prettiest.
"I stayed patient and tried not to make any silly bogeys, but I made one down the last. I'm happy with the way I'm playing, I've been steady rather than spectacular.
"There's plenty of opportunities out there, but it's easy to get carried away and make silly bogeys. It's a lot in the mind this golf course."
Gallacher went one better than Bjorn with seven birdies before his only bogey which arrived at the 17th after he found sand from the tee.
The Scot also made a bit of a mess of the 18th after firing his approach into the grandstand, but recovered to get up and down from the drop-zone to grab a share.
It proved a much tougher day for some of the bigger names as the likes of Francesco Molinari, Darren Clarke and Branden Grace all missed the halfway cut, along with defending champion Richie Ramsay.
