Sky Lantern will kick off her season in Wednesday's Lanwades Stud Nell Gwyn Stakes at Newmarket after a late change of plan.
Trainer Richard Hannon had intended to run his Moyglare Stakes winner in Saturday's Dubai Duty Free Stakes at Newbury, with stablemate Maureen heading to Newmarket instead.
However, the Hannon team believe the ground will be in Sky Lantern's favour, and have opted to shoulder a 3lb penalty rather than run her on unsuitable ground at Newbury.
That leaves Maureen to head to the Berkshire track for her seasonal bow.
Assistant trainer Richard Hannon jnr said: "Maureen is going to Newbury now and Sky Lantern goes to Newmarket.
"She was primed for Newbury anyway so it makes no difference. We put them in both races so we could have the choice.
"The reason we preferred Newbury for Sky Lantern was that she wouldn't have a penalty there, but the ground is going to be soft and she does need good ground."
Ed McMahon's Winning Express and the Mark Johnston-trained Baileys Jubilee finished second and third respectively in the Cheveley Park Stakes last term and are set to cross swords again, along with eighth-placed Jadanna.
Henry Cecil's Hot Snap, a half-sister to multiple Group One winner Midday, and William Haggas' Lady Nouf are interesting contenders, having won their sole racecourse starts to date.
Hannon also field Light Up My Life, while Luca Cumani's Nargys claimed second in the Rockfel Stakes on her final start of 2012.
Coincidently, Exactement, Reyaadah, Sorella Bella, Sound Of Guns and Waterway Run complete the field.
