The 40-year old Brown, won the 2008 Johnny Walker Classic, and is set to make a rare apeparance back on the European Tour next week, scheduled to play in the Russian Open.
He believes he has a shot to get the win at the $110,000 tournament tomorrow afternoon.
"I don't hit it as far as some of these young boys but I hope my experience counts for something because this is a very tough track," he said.
Kiwi Nick Gillespie fired the round of the day, matching Brandson's 67 to get to even-par and a share of 17th. Daniel Pearce sits at four-over par alongside Michael Long, while Gareth Paddison's disappointing tournament has him at six-over.
Brad Shilton (nine-over) and Kieran Muir (11-over) have also made the cut but sit well out of contention.
