David Wachman, who won the big race at the Curragh on Sunday, will be out to take the featured Follow Leopardstown On Facebook Race on Wednesday.
His Alkazim remains a maiden after six starts, though, and faces stiff opposition, with Aidan O'Brien saddling Vault and Furner's Green.
Dermot Weld's Hit The Jackpot also looks promising after taking a Galway maiden last summer, but the benefit of race fitness could tip the balance in favour of Honourable Emperor, who is chasing a hat-trick after a couple of narrow wins at Dundalk.
The Spin 103.8 Handicap also provides a generous prize and sees Glor Na Mara take a huge step up in trip.
Jim Bolger's charge ran on for third over six furlongs at the Curragh on Sunday, though whether that warrants a step up to a mile and a quarter remains to be seen.
Jazz Girl signed off last year with successive wins and has to be feared, while Roman Flight blew away any cobwebs with a fourth place at Dundalk earlier this month and should be suited by this trip.
The meeting begins with the EBF Fillies' Maiden, which sees O'Brien saddle three newcomers, though Weld's French Hen, a half-sister to Irish Oaks heroine Blue Bunting catches the eye.
Taigan steps up in trip for the Summer Festival Series Maiden and on pedigree that should be ideal, so the fact he was quick enough to go close over much shorter bodes well.
Both Fairy Wing and Eclipseoftheheart bid for a hat-trick in the Intervarsity Challenge Handicap, while the Ross Nugent Foundation Handicap sees Spunky trying to end a run of three straight seconds.
