MOSCOW, July 28, 2013 (AFP) - Hoey set up his fifth European Tour victory with Saturday's decisive seven under par round of 65, to leave him five shots clear overnight.
The 34-year-old, who had missed seven of his last ten cuts, finished with a 16-under par total of 272.
Last year's winner Alexandre Kaleka of France and Englishman Matthew Nixon were the closest challengers, finishing on 12 under, with Joachim Hansen of Denmark one shot further back in fourth.
Hoey told europeantour.com: "I have absolutely loved the golf course this week.
"The putting was the key for me. I have been working hard on that a lot recently and the improvement is really showing because I was making a lot of birdies.
"That is the main difference at this level. You have to be able to make a lot of putts because the standard is so high these days that it usually comes down to who makes the most putts.
"It's pretty amazing to think that I have won five European Tour titles.
"It is a great feeling to win and every time you do it you just want more and more. Hopefully I can get at least another one before the end of the season.
"It has given me a great boost. I am not the most consistent player in the world but when I get into these positions I usually do okay."
Hoey dropped just one shot throughout the day, at the 12th, and his lead was cut to two by Kaleka and Dane JB Hansen.
But a birdie at the 17th steadied nerves and Kaleka (bogey) and Hansen (double bogey) both dropped strokes at the last to card 68s.
China's Liang Wen-chong, Frenchman Gregory Havret and English duo James Morrison and Mark Foster finished in a tie for fifth on 10 under.
