O'Brien trio in Guineas reckoning Aidan O'Brien can choose from Adelaide, Geoffrey Chaucer and Giovanni Boldini in the French 2000 Guineas at Longchamp on Sunday. Giovanni Boldini has the best form in the book after he was just denied in the Breeders' Cup Juvenile Turf, but the other two possible Ballydoyle representatives are still unbeaten. Richard Hannon's Shifting Power intriguingly still holds an entry after he finished fourth behind stablemate Night Of Thunder in the 2000 Guineas at Newmarket on Saturday. Powerful owners Qatar Racing could give End Of Line (Andrew Balding), God Willing (Ed Dunlop) and Lat Hawill (Marco Botti) the chance to shine in the race officially known as the Poule d'Essai des Poulains, while the unbeaten Muwaary is in contention for the John Gosden team. Karakontie is one of the leading challengers from the home team, with Galiway a worthy ally for Andre Fabre, who could also run the Godolphin-owned Decathlete. The well-regarded Kiram and Salai remain in the hunt for Jean Claude-Rouget, with Charm Spirit, fifth in the Guineas at Newmarket at the weekend, also among the 20 contenders at this stage. J Wonder and Al Thakhira could clash again after the pair featured among 23 contenders for the Poule d'Essai des Pouliches, also know as the French 1000 Guineas, on the same card. The Brian Meehan-trained J Wonder beat Marco Botti's Al Thakhira just a head in the Fred Darling at Newbury and both skipped possible runs in the Newmarket Guineas to head here instead. Charlie Hills' Queen Catrine is also still in the reckoning after sidestepping the Newmarket Guineas, while Rae Guest's Cape Factor could also take her chance after lifting a Listed prize on her final start last term. Aidan O'Brien is typically well represented at this stage with Wonderfully and Palace, while Paul Deegan's Avenue Gabriel is another Irish-trained possible. Xcellence leads the home team after beating subsequent Newmarket winner Miss France into sixth in the Prix Imprudence last month. This Time, who claimed fourth in the Imprudence, and fifth-placed Marbre Rose could try their luck again for Alex Pantall and Freddy Head respectively, while four of the five runners in last month's Prix de la Grotte reoppose, headed by the Jean-Claude Rouget-trained winner Lesstalk In Paris. Runner-up Straight Thinking could go again for Andre Fabre, with Indonesienne and Bocaiuva also out to reverse the Longchamp form. Fabre has a second string to his bow in Fintry, as does Rouget, who also has Avenir Certain, while Alain de Royer-Dupre has Mintaka and Veda entered for the Aga Khan.
