Another feast of top-quality racing action beckons at Randwick this Saturday with day two of The Championships.

The headline act is the Queen Elizabeth Stakes, where Chris Waller's mighty mare Autumn Glow will be looking to extend her unbeaten run to 12.

In the other Group 1s, the imports will again dominate discussions in the Sydney Cup, while the staying fillies battle it out in the Australian Oaks and the miler mares lock horns in the Queen of the Turf.

Further south, there's black type in Adelaide, with six stakes races headed by the Group 3 Auraria and R.N. Irwin.

You'll find Australia's best form guide for Saturday's Caulfield, Randwick, 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.
