Thomas Aiken and Paul Waring will share a three-shot lead heading into the final round of the Nordea Masters after a thrilling day of ebb and flow at Hills Golf Club.
Waring entered the third round two shots clear of Aiken but the South African turned in 32 to lead by one and his advantage was two shots with six to play.
A dramatic turnaround saw Englishman Waring hold a two-shot advantage of his own after a birdie on the 17th, before another two-shot swing on the last left the duo tied at the top at 12 under.
Dane Thorbjørn Olesen and 2006 champion Marc Warren were three shots off the lead, one clear of German Maximilian Kieffer.
Waring is playing his 200th European Tour event this week in his 11th season since coming through the Qualifying School, having missed large chunks of the 2011, 2012, 2015 and 2016 seasons with wrist and shoulder injuries.
He finished a career-best 60th on last season's Race to Dubai Rankings presented by Rolex, with a runners-up finish at the Joburg Open and a third at the Trophée Hassan II, but a tie for ninth in Morocco has been his only top ten this season.
“It's not always a technical thing for me, I've had a bit of an issue between the ears, shall we say,” he said. “I just get in my own way a little bit. I feel like I'm moving past that point a little bit better and I'll keep getting better the more often I put myself in this position.
“There are still 18 holes of golf to play so I'm not getting too carried away, there's still a big job to do.
“I know Thomas quite well, played with him a few times. He's a good player and knows how to win. Last group on a Sunday, it's all you can ask for.”
Aiken has been an ever-present on Tour since coming through the Qualifying School for the second time in 2008 but the last of his three wins came in 2014, and his week represents a welcome return to form after one top ten in seven made cuts from 19 events this season.
“The conditions were a little tougher today the wind was up from the last two days and swirling as usual,” he said. “I started off really playing well and kept it going. Unfortunately, it didn't finish quite the way I would have wanted to but I was giving everything a go and trying to push and stretch those scores out.
“If you told me I was going to shoot 67 at the beginning of the day I would have taken it. I'm in a nice position going into tomorrow so it should be fun.”
Aiken holed a 15-footer on the second and when he got down in two from 80 feet on the par five third, he shared the lead.
The 35 year old hit an excellent tee-shot into the fifth to hit the front on his own but Waring got even closer in the group behind and the duo led by four shots.
Aiken holed a 12-footer on the eighth to get to 13 under but Waring hit back again with a monster putt on the tenth to join the lead and further extend the gap between the leading pair and the rest.
There was then a two-shot swing on the 12th as Aiken made a remarkable up-and-down from a downhill lie on the bank for a birdie, while Waring dropped a shot after finding the water.
But Aiken found sand off the tee at the par three 15th and failed to get up and down, with three-putts on the next two greens making it three bogeys in a row and Waring was back ahead.
The 33 year old put his second on the 17th green in a similar position to Aiken but he needed just one attempt to get down from distance and led by two.
Aiken took advantage of the par five last to cut the gap to one but Waring dropped a shot after putting his second behind a rock and needing a drop.
Olesen has five top 15s in his last eight starts including his maiden Rolex Series win at the Italian Open and knows a good finish in Gothenburg could go a long way to securing his place on the Ryder Cup Team.
The five-time European Tour winner bogeyed the first after finding sand but holed a very long putt on the fourth and put his tee-shot to eight feet on the par three next. A double-bogey after finding the water on the seventh dropped him back but he holed a long putt on the eighth to turn in level par.
Another long putt on the 11th was followed by a ten-footer on the 12th and when the 28 year old hit a stunning approach into the 16th, he was well positioned for Sunday.
Warren started with a bogey but birdied the second and then made four in a row from the ninth thanks to some dialled-in iron play. He dropped a shot at the 14th but picked it back on the 16th before missing a short putt to get into double figures on the last.
Kieffer fired a 66 with seven birdies and three bogeys to sit a shot clear of Australian pair Adam Bland and Lucas Herbert, and England's Lee Slattery.
Italian Nino Bertasio, Frenchman Sébastien Gros, Scotsman Scott Jamieson and England's Robert Rock completed the top ten at six under.
