The John Moore stable is not yet enjoying a vintage season by its own high standards, but the trainer looks a key factor at Sha Tin tomorrow for punters chasing the elusive Triple Trio at the mixed meeting.

Moore should provide banker material in at least the second and third legs with Maroon Prince (Neil Callan) and Cultural City (Derek Leung Ka-chun), and possibly even in the first leg with the in-form Thanksgiving (Tim Clark).

In the middle leg, three-year-old Maroon Prince has been a revelation since he was switched to the all-weather surface, winning at long odds in December before backing that up with a solid fourth to Hearts Keeper last time.

On both occasions, Maroon Prince did a good job after drawing wide at the start, but barrier four might allow him an easier run tomorrow and the youngster looks likely to be in the finish again, as does his last-start conqueror.

Also a three-year-old with some upside, Hearts Keeper (Ben So Tik-hung) has found a niche on the artificial surface with a win and a second in two outings and he is also drawn low. He showed last time that he is able to be ridden handy to the lead and that is always a plus on the surface.

Away from the pair of smart three-year-olds, this looks an open affair, with cases to be made for consistent Flying China (Brett Prebble), Regency Champion (Matt Chadwick), likely leader What A Heart (Alvin Ng Ka-chun) and the lightweights, Nobody But You (Vincent Ho Chak-yiu) and Supreme Hong Kong (Umberto Rispoli).

The opening leg looks fairly clear cut, especially after Divine Diya's win last weekend highlighted the prospects of Good Good View (Zac Purton). The Dennis Yip Chor-hong-trained gelding looked unlucky to be beaten by Divine Diya on debut over 1,200m and the step up to 1,400m won't bother this promising youngster by former top miler-middle distance galloper Intergaze.
