The Group Three Desmond Stakes features at Leopardstown and following the wins of Carribean Sunset and Famous Name in the past two renewals, Dermot Weld seeks a third straight success through Emulous.
The daughter of Dansili has failed to add to her juvenile win in a couple of outings this term, however, and faces stiff competition from fellow three-year-old filly Akdarena.
John Oxx's contender ran below par when sixth in the Irish Oaks but had previously finished third in the Pretty Polly and the drop back in distance is likely to suit.
Aidan O'Brien's Dewhurst hero Beethoven also represents the Classic generation and he, too, drops from Group One company after finishing fourth in the Sussex at Goodwood.
Dandy Boy and the vastly experienced King Jock complete the line-up and neither can be ruled out confidently.
The seven-race card commences at 5.30 with the Tattersalls Ireland Ltd EBF Fillies Maiden and Pat Fahy's Galway runner-up Ballybacka Lady arguably sets the bar at which the newcomers must aim.
Money for Constant Charmer or Eva's Time would have to be taken seriously but the Ger Lyons-trained Break Bread, a full sister to the stable's Berg Bahn, who won first time out, is of particular interest.
O'Brien takes the wraps of a couple off Montjeu colts, namely Auguste Renoir and Eagle Canyon, in the Tattersalls EBF Maiden, while he also runs Outrider, who will have learnt plenty from his Naas debut experience.
The likeable Collingwood bids for a second course win in the "Sharon Shannon Big Band" Handicap, while last-time-out scorers Strandfield Lady and Belle Noverre clash in the Racing Rocks At Leopardstown Handicap.
David Marnane's lightly-raced Teak is one to note in the Derrinstown Stud Apprentice Handicap, but the trainer's duo, Countess Salome and Pinnk, have Fedora, Mount Abora and Truth Seeking to beat in the concluding Irish Stallion Farms EBF Fillies Maiden.
