After two hard runs from poor draws Smolda will start from barrier three in the last heat, where the step up to 2536m will also suit.
He will be favoured to run to the front and win.
But even if he can't he will be able to sit parked and control the race and with key rivals Bling It On and Beaudiene Boaz drawn wide, Smolda gets the perfect chance to go into the final a winner.
Franco Nelson was disappointing by his early spring form standards on Tuesday but has also drawn barrier three tomorrow night in a race that should be dominated by Lennytheshark (barrier one) and Bettors Fire (two).
So Franco Nelson should sit just off the speed and driver Dexter Dunn gets the perfect chance to sneak him into a placing and therefore the final.
Defending champion Lennytheshark was disappointing when he finished only fourth, his first unplaced run in 18 months, on Tuesday but gets the perfect chance to bounce back from the ace.
Tuesday's defeat has cost him his place at the head of the markets, with Hectorjayjay now the $2.40 favourite for the final with the New Zealand TAB.
He was supersonic pacing his last 1200m in under 1:23 to win untouched on Tuesday and from another good barrier tomorrow night will be expected to lead and win again.
While victories have been hard to come by for the small New Zealand team at the carnival that should change away from the Interdom heats tomorrow night, with Smolda's four-year-old stablemates Piccadilly Princess and Mr Mojito both favoured to win their feature races.
Both have drawn barrier two and they give Purdon a rare, realistic chance at training a Gloucester Park treble, a feat that may not have ever been accomplished by a New Zealand trainer before.
The all-important barrier draw for the Inter Dominion final will be conducted on Sunday.
