French import Prince Cheri will be on trial to prove his worth for one of Australia's biggest races in Saturday's Kingston Town Stakes at Rosehill.

Trainer David Vandyke has Caulfield Cup ambitions for the five-year-old but they won't be entertained unless Prince Cheri performs this weekend.

"If we're going to be looking at the Caulfield Cup seriously then he just has to win in this field, down on the limit," Vandyke said.

Prince Cheri is unexposed. He has raced just five times, twice in France for a 2400m victory and a stakes placing over the same trip.

His three starts for Vandyke have yielded two wins and a close-up third and Saturday's race will be his first Australian assignment beyond 1600m.

Despite his inexperience, Vandyke is confident the five-year-old has the race smarts to match his raw ability.

"He is quite an exceptional horse when it comes to his temperament, on and off the track," Vandyke said.

"He's a really intelligent horse. He is switched on and he knows what to do now."

Vandyke will hold a strong hand in the Kingston Town Stakes (2000m) because he will also start the in-form Less Is More.

Jay Ford has been the regular partner of both Vandyke-trained gallopers and had the choice of mounts.

"He was pretty keen to ride Prince Cheri," Vandyke said.

A last-start winner of the Premier's Cup, Less Is More is following the same path as Vandyke's former star Lamasery two years ago.

Lamasery won the Kingston Town Stakes and Colin Stephen Quality before a fine third in the Group One Metropolitan.

Blake Shinn, who rode a double at Randwick last Saturday and added a winner at Warwick Farm on Wednesday, has picked up the ride on Less Is More.

"He's done a treat. The 2000 metres is perfect for him and he's had a lovely preparation," Vandyke said.
