HAPPY VALLEY on Wednesday night

Howard Cheng Yue-tin looks the spoiler to what oddsmakers labelled a two-man Jockey Challenge in opening prices. In another Whyte-Prebble free zone, with the top riders suspended, Weichong Marwing was posted a $2.80 favourite when prices went up for tonight's final Happy Valley Challenge of the season, with Sunday's Sha Tin victor, apprentice Matthew Chadwick, a tight second pick at $3.40.

While both have solid chances, the contest looks more open than that with a number of riders looking to have one or two plum rides mixed with hopefuls. A single upset result could swing the Challenge and punters might find better value away from the favourites.

Darren Beadman fans might fancy a piece of the $15.00 posted last night as he has two strong chances in Ever Beauty (race five) and White Jade (race eight), but with only five rides he will have to conjure something clever out of the remaining mounts to be the winner.

Cheng, though, has eight mounts, most of them with some claims to at least minor points and was listed at $7.50 in opening odds. His mounts include honest Kingston Winner, Steel Nerves and Royal Portrait, before coming home with winning chances - Speedy Star and Gilded Flight - at the back of the card. But perhaps his best chance will be Aipoder Image in the first - he came from last in a big effort for second last time and can round them up to break his maiden tonight, despite the outside draw.
