Aidan O'Brien goes for his 17th Group One win of the season when Halfway To Heaven faces nine rivals in the Blue Square Nassau Stakes at Goodwood on Saturday.
The filly has already contributed to the Irish trainer's impressive tally by landing the Irish 1000 Guineas on her latest start.
The daughter of Pivotal steps up to a mile and a quarter for the first time as she bids to follow up her trainer's win with Peeping Fawn 12 months ago.
O'Brien has taken out his other four remaining entries but there is another strong Irish candidate in Lush Lashes.
Jim Bolger's charge opened her account at the highest level in the Coronation Stakes at Royal Ascot but showed she stayed this distance when winning the Musidora Stakes at York in May.
Her trainer sent out Alexander Goldrun to strike here in 2005 and run Ouija Board close 12 months later.
Michael Stoute has won this race seven times and he relies on the five-year-old Heaven Sent this time while Henry Cecil goes for win number six with Passage Of Time.
A star-studded line-up is completed by Majestic Roi, Soft Morning, Cape Amber, Classic Remark, Muthabara and Sugar Mint.
