Happy Valley's dominant stable, the Caspar Fownes yard, looks ready to strike in tonight's Tung Wah Centenary Challenge Cup (1,000m) with the lightly raced four-year-old Nirvana. The grey put the writing on the wall as a future winner in his controversial last-start eighth up the Sha Tin straight behind South China Elite, but most importantly he has come up with gate one and a race that should be run to suit. Nirvana's first-up run over the Valley 1,000m was also an eye-catcher behind Glory Years, but a stewards' inquiry into the run at Sha Tin certainly shone a spotlight on him that day. Jamie Stier's panel grilled jockey Shane Dye over a section of the race in the final 150 metres when Dye stopped riding his mount forwards, despite having an open gap in front of him between the outside rail and race leader Shy Baldy. Dye explained to the stewards that he was concerned at another runner that was shifting out and into the path of Shy Baldy and said he felt the gap was going to close before he got through it.An understanding stewards panel decided not to take action over the incident, according to the stewards report, as it could not be satisfied that Dye had cost Nirvana a place. But the incident certainly cost Nirvana ground and, being only his second run for the season and fifth in Hong Kong overall, it would seem logical to expect some improvement from the horse. Though he looks to be a backmarker in these 1,000m races, gate one should assist him to be appropriately placed and the range of speed engaged gives every reason to believe the pace will be on for him to have the last run. Wine Win, Plezayre, Thunder Flash and Flag Finder are all quick horses who like to press forward so the tempo should be generous. The John Size-trained Super Honey (Douglas Whyte) is an interesting proposition for the same reasons of inside gate and the fact he will be running on. He finished last season with a Happy Valley 1,200m win and opened the new one with a worthwhile effort behind Top Top Light, but Super Honey has not fired a shot in starts at Sha Tin and on the dirt since. The return to the city track should make him a more viable proposition, even if the distance looks on the short side.
