Begg said Zakouma's last start had been effectively a 2000m barrier trial, but the set-weights conditions of the contest do concern Begg as Zakouma, who has untapped potential, is weighted the same as Sydney Cup winner Changingoftheguard.
"He's got to go the distance and he's not well-weighted under the conditions," Begg said.
"I don't understand why it's a set-weights race.
"Outside three-year-old Classic races, I can't think of one, while the winner gets free passage into the Melbourne Cup and then goes back to a handicap, so why not make this a handicap."
Zakouma has yet to race beyond 2000m since joining Begg's yard after starting his career with Pat Carey and Harris Walker at Mornington.
In his three-year-old days, Zakouma ran second over 2200m at Bairnsdale and fourth over 2400m at Caulfield before moving to Begg.
What Begg wants to see on Saturday, is a steady tempo with Zakouma ridden patiently as the gelding bids to get the trip.
