Two of the great races on the Australian calendar go head to head this week, one of them 147 years young and the other just 10 years old.

The local, imported and overseas stayers do battle in the Caulfield Cup, while the best sprinters in the land will try to topple Hong Kong superstar Ka Ying Rising in the $20 million Everest at Randwick.

The King Charles III Stakes for the milers and the Kosciuszko for the country sprinters add intrigue to the Randwick card, while the Sportsbet Classic for the derby-bound three-year-olds, the Thousand Guineas Prelude for the fillies and the Caulfield Sprint are on the undercard at the Heath.

In Adelaide, more Victoria Derby contenders will be going around in the Hill Smith Stakes at Morphettville.

You'll find Australia's best form guide for Saturday's Caulfield, Radndwick, Doomben and Morphettville meetings in this week's Best Bets.

On pages 4 and 5 you'll find four-state selections from some of the nation's leading form analysts as well as our popular Black Bookers, Sectional Stars and Video Stars features.
