William Buick is undecided as to which of Soliloquy or Wild Illusion he will ride in the Qipco 1000 Guineas on Sunday.
Wild Illusion showed the better form at two, winning the Group One Prix Marcel Boussac, but Soliloquy made an impressive reappearance in the Nell Gwyn at the Craven meeting.
And it is the fact the latter has a run under her belt which could tilt Buick towards her.
“I’ve not made my mind up yet. They are two high-class fillies and nothing we know splits them. That (Soliloquy having a run) could be a deciding factor,” said Buick.
“I will have a good look and make my mind up. I think it’s really tough. The more I think about it, the more I confuse myself.”
He added: “Soliloquy has always been very smart and that (Nell Gwyn) didn’t surprise me at all. She was a big two-year-old and was always going to improve for the winter. She is beautifully bred.”
Connections of Liquid Amber believe their filly is heading towards the Classic “under the radar”.
The daughter of Kitten’s Joy broke her maiden in startling fashion in the Group Three Flame of Tara Stakes at the Curragh in August.
Trained by Willie McCreery, she will race in the famous Niarchos family silks carried to victory in the race by Miesque in 1987.
“She only ran twice last year and this will be her first start of 2018 so from that point of view I suppose you could say she’s under the radar,” said Alan Cooper, racing manager for the owners.
“She broke her maiden in a Group Three, she’s wintered well and has been pleasing Willie.
“The thought at the moment is to run her on Sunday and hopefully she can give a good account of herself and we can map out a programme from there.
“Willie has a very nice filly in Mary Tudor who is going for the Irish Guineas so he has a pretty good idea where he stands in that division.”
Liquid Amber’s price ranges from 16-1 to 20-1.
With Andrea Atzeni required to ride Madeline for owner Sheikh Mohammed Obaid, Frankie Dettori has picked up the ride on Roger Varian’s Altyn Orda.
“I went to see Roger Varian and we watched a video of Altyn Orda,” Dettori said in his Ladbrokes blog.
“She is interesting because in both of her races, she was sharp and she really finished the race strongly. The mile will suit her.
It looks wide open but I think she will run a big race.”
