Weight-for-age racing often produces tactical battles and jockey Damian Browne is looking forward to that scenario in the Group Two Eagle Farm Cup.

With only six runners in Saturday's race, Browne is relishing the prospect of a battle of wits with his fellow riders.

"Weight-for-age racing lends itself to a bit of cat and mouse between the best horses and the best jockeys and they're enjoyable to ride in," he said.

"It's not a cream-of-the-crop field but most of them have contested some of the better quality races this season and it should be an interesting battle."

Browne rides Quintessential and believes the mare's adaptable racing style makes her a genuine winning prospect even though she's only rated a $10 chance.

"She can race anywhere in a field and handles all types of track conditions," he said.

Heavy rain on Thursday will ensure a rain-affected track for Saturday's meeting and Browne believes that will assist the mare's chances.

"We don't need much more rain for it to be a pretty ordinary track and she's performed under those conditions on more than one occasion," he said.

Quintessential won last year's Queensland Oaks at Eagle Farm on a heavy surface and is coming off a win in the Chairman's Handicap at the same track in similar conditions at her last start on May 11.

While Browne acknowledges Quintessential hasn't developed physically to any significant degree since last year's carnival he believes her Chairman's win is evidence she is in top form.

He regards the Peter Moody-trained duo Lights Of Heaven ($2.80) and Manighar ($2.90) as the toughest for Quintessential to beat.

Leon Corstens has removed blinkers and added winkers to Zabeelionaire following the four-year-old's poor effort in the Doomben Cup when he finished last to Beaten Up.
