Racing:Finsceal Beo will face a maximum of 13 rivals in the Boylesports 1000 Guineas as she attempts to atone for a near-miss in the French equivalent.
Jim Bolger's filly won the Newmarket version in thrilling style and she will attempt to match the feat of Attraction who won both races in 2004.
Bolger also has Gaudeamus in the race while Finsceal Beo could clash again with her nearest pursuer from Newmarket, John Oxx's Arch Swing.
Mick Channon's Treat (fourth), Richard Hannon's Indian Ink (fifth) and Stan Moore's Satulagi (ninth) could also reoppose.
Other notables include Tommy Stack's Alexander Tango and Kevin Prendergast's duo of unbeaten Boca Dancer and Dimenticata.
Aidan O'Brien has two possibles, Diamond Necklace and Peeping Fawn while Dermot Weld could run Truly Mine and Offbeat Fashion.
The John Murphy-trained Silk Dream completes the possibles.
Connections of Treat are delighted to have secured the services of Johnny Murtagh for their filly.
Murtagh has enjoyed big-race success for the owners, Highclere Thoroughbred Syndicate, before on Petrushka in the Irish Oaks and spokesman Harry Herbert is hoping lightning can strike twice.
"She's in good form, she'll have a breeze tomorrow morning and as long as Mick is happy with her, she will head to Ireland. She hasn't done a lot since Newmarket," said Herbert.
"She was in season last week so she had a easy time of it but she will have a nice breeze tomorrow and then it will be all systems go.
"Johnny Murtagh will ride her and we think the stiff mile of the Curragh will be to her advantage. Obviously a bit of rain will help her but it doesn't look as if we are going to get any.
"We just felt that we wanted to have another go at a mile before we stepped her up in trip.
"We think she might be suited to going a bit further but her pedigree very much suggests that she is a miler so we think it is right to give her another chance.
"We would be delighted if she can run another race as good as Newmarket and if she can get a place or two nearer, that would be a bonus.
"She is a lovely, scopey filly which makes us think she wants further than a mile but there isn't much in her pedigree that stayed much beyond seven.
"She has entries in the Ribblesdale and the Coronation at Royal Ascot and hopefully this weekend will tell us in which direction to point her."
