Fresh from an upset win aboard Dashing Fellow on Sunday, light weights and low draws can help Karis Teetan strike again on Wednesday night at Happy Valley.

The Mauritian Magician was able to steal a five-runner Class One on Sunday with a front-running ride, and heads to Happy Valley with a strong book, headed by a number of horses drawn low on the C course.

Dynamism looks a great chance from barrier three and bottom weight in the feature race of the night, the Happy Valley Vase, but it is in the first two legs of the Triple Trio where Teetan can steer punters in the right direction on Sum Win Dragon and Generous Heart.

Sum Win Dragon seems to love the extra give in the ground at the city track and stormed home for second, beaten just a short head by Mutual Joy two weeks ago.

Sum Win Dragon might have been flattered by the strange structure of the race, with a slow pace up front inviting mid-race moves.

Still, he has an excellent Valley record, relatively speaking, having finished top four in five of his eight runs there and notching his only career win over 1,650m just over a year ago.

On paper, a lack of speed looks worrying for the backmarker but it’s possible that Sum Win Dragon gets a similar race set up to last time, this time at 1,800m, with a number of horses candidates to get going early.

Ten pound claimer Dylan Mo Hin-tung heads to Happy Valley for the first time and trainer Danny Shum Chap-shing will be instructed him to make use of his weight advantage, especially after Casa Master stole a Class Four with the help of an aggressive Zac Purton ride in January.

Joao Moreira almost has to go forward from gate 11 on Po Ching Treasure, which could create more pressure, and Cash Courier won’t be too far away with apprentice Jack Wong Ho-nam up.

Dutch Windmill (Vincent Ho Chak-yiu) will be in the market while a decent double banker is top weight Super Form (Sam Clipperton).

Super Form shocked punters first-up this season at 93-1 and although the five-year-old hasn’t won since, Tony Millard has kept the gelding racing consistently and barrier three should allow Clipperton to find a perfect spot.

In race five, Teetan looks to build on his combination with Dennis Yip Chor-hong on four-year-old Generous Heart in the second leg of the TT.

Teetan has only ridden the lone winner for Yip and his overall record for the trainer of one from 32 doesn’t read well.

However, Teetan and Yip have placed with their last three runners together, including a second with Generous Heart last start at Happy Valley, the gelding’s first trip across town.

Racing’s superstars shine on the world’s biggest stages

Yip’s ISG finds itself in the rare situation of working into Class Three without winning, going within a short head of breaking through three starts back over 1,400m at Sha Tin.

Generous Heart then copped a wide draw when running into a rampant Nothingilikemore over the same course and distance first time up in grade.

Last start, Generous Heart showed surprising gate speed from barrier two, Teetan easing out of the early fireworks and settling three-back on the fence.

He found clear running and hit the front 100m out, only to be grabbed right on the line by All My Gains.

Stayer Helen Charisma can keep the John Moore-athon rolling

This time from gate three, Teetan can find a similar sit in a race with an abundance of on-pace runners that should ensure Generous Heart again gets every opportunity.

Nash Rawiller will stick close on Diego Kosta, while Kei Chiong Ka-kei will be aggressive from her low draw and Alvin Ng Ka-chun should be too, even if both are coming back in distance.

The likely favourite, Powermax (Moreira), has drawn 12 as he chases three straight wins at the course and distance.
