Racing Post tipster Dave Randall outlines his best bets on the card.
The Group 1 1m Irish 1,000 Guineas for three-year-old fillies takes pride of place on a cracking card from the Curragh and the short-priced favourite Tahiyra is going to be extremely hard to beat.
The daughter of Siyouni travelled strongly in a prominent position throughout before quickening clear for an impressive debut success over 7f at Galway in July last year and her in-form trainer Dermot Weld gave the filly a big vote of confidence by pitching her into the Group 1 7f Moyglare Stud Stakes at this course on her only other start as a juvenile in September.
On that occasion, she had today's clear second-favourite Meditate in behind when running out a ready winner.
Weld is renowned for giving his horses the time they require to come to themselves and it was telling in the run up to her reappearance in the 1,000 Guineas at Newmarket that he felt she was a couple of weeks away from being at concert pitch.
She travelled like the best filly in the race but got narrowly worried out of a Classic success by Godolphin's Mawj, who had the conditioning benefit of two successful runs earlier in the year at Meydan.
The front two pulled over seven lengths clear of the third and Meditate was back in sixth.
Meditate may pose more of a threat given the benefit of that return but, while Mawj lies in wait in the Coronation Stakes at next month, the coast is clear for Tahiyra to strut her talent and she is a shortie worth siding with.
Tahiyra has been given a strong vote of confidence in the Irish 1,000 Guineas but a small each-way saver in the same race is also advised.
's Jackie Oh never raced as a juvenile but she showed distinct promise in her two runs this spring when first and second on heavy ground at Naas and Navan.
Being by Galileo, she is expected to relish this drop back to 1m on a quickish surface and can continue her progression as she steps up from Listed to Group 1 company.
O'Brien is 5-34 in this race since 2013 and all five winners were sired by Galileo. Jackie Oh has decent place claims at the very least.
A field of six will face the starter in a fascinating running of the Group 1 extended 1m2f Tattersalls Gold Cup for older horses at the Curragh.
Half the field breaks away from the rest as they are officially rated in the 120s.
Luxembourg (122) is one of those three, and it is likeable that he has won over this course and distance, but the body of his work isn't as deep as the other two.
Vadeni (124) and Bay Bridge (122) have registered four and three Racing Post Ratings (RPRs) in the 120s whereas Luxembourg's 124 for his Irish Champion Stakes success in September is an outlier in his regard.
Bay Bridge and Vadeni ran third and fourth in the Prix Ganay at Longchamp on their returns, but Vadeni's excellent second in the Arc last October is the pick of the form on offer and he is taken to reverse the placings.
