Northern Ireland's Michael Hoey will take a five-shot lead into the final round of the M2M Russian Open after shooting a seven-under 65 on Saturday.
Hoey had six birdies and an eagle, with a five on the 11th the only bogey on his card at Tseleevo Golf & Polo Club near Moscow, to move to 14 under par and open up a healthy lead over England's Matthew Nixon and Sweden's Rikard Karlberg in joint second place.
South Africa's James Kingston and France's Alexandre Kaleka are a further stroke back on eight under, while JB Hansen, Mikko Korhonen and James Morrison are in a three-way tie for sixth place on seven under par.
Hoey, who has four European Tour victories to his name, the last coming in the Trophee Hassan II in 2012, was out in 31 on Saturday.
The 34-year-old has not finished better than 25th on European Tour so far this season and missed seven of his last 10 cuts coming into the event.
"It was one of those days where everything went my way for the most part," Hoey, who is down in 142nd position in the Race to Dubai, told europeantour.com.
"I played really well and was swinging the club well, but I got a few breaks here and there that really helped the score.
"I holed a 70-foot putt on the ninth for example - that's was probably the biggest break I had out there. You just don't really expect to hole those ones so that was a bit of a bonus.
"I am making a lot of putts this week and that is always the difference at this level. It's all about putting."
However, Hoey knows anything could still happen on the final day, and he is not yet contemplating his fifth European Tour win.
He said: "Obviously I have a good lead but you just can't take it for granted. Things went my way today but it might be someone else's day tomorrow.
"I am just going to go out there and try to enjoy it. I have been in positions to win before and finished it off and that will help a bit, but you still need to hit the shots and hole the putts."
