US Navy Flag, Europe's champion juvenile last year, and Gustav Klimt head Aidan O'Brien's bid for a 12th victory in the Tattersalls Irish 2,000 Guineas – a race the Ballydoyle trainer first won with Desert King in 1997.
Success for one of O'Brien's four runners would give the trainer a 40th Irish Classic win with US Navy Flag and Gustav Klimt attempting to improve on their efforts in the Guineas at Newmarket and Longchamp.
Ryan Moore has opted to partner US Navy Flag, who finished fifth in the French equivalent, in which he was in the lead when stumbling under three furlongs from the finish.
Completing the Ballydoyle quartet are Threeandfourpence and the the maiden Spanish Point, who is blinkered for the first time. The race is off at 4.10.
Unless there is a raceday plunge on a Ballydoyle runner, it is Britain who will have the horse to beat in the race with Elarqam, favourite on Friday and who is well fancied to improve on his fourth-placed finish in the English 2,000 Guineas.
The Fozzy Stack-trained Zihba goes into the race with an unblemished record and steps up to the top level for the first time.
Unraced last season, he is three from three since starting out in December and booked his place in this line up when beating older horses in the Group 3 Amethyst Stakes over the same trip at Leopardstown on his most recent start.
Bought by Al Shaqab Racing since his Leopardstown win, the son of Choisir is the mount of Chris Hayes, who will be seeking a second win in the race having scored on Awtaad two years ago.
British trainers have won six of the last ten runnings of the Group 2 Weatherbys Ireland Greenlands Stakes (3.35) and Brando and Tasleet will be bidding to add to that impressive record.
Outside of that sprint and the showpiece race, there is a fantastic undercard on the opening day of Guineas weekend at the Curragh, with the first race underway at 1.50. The ground is good at the track.
