TRAINER Gary Ng Ting-keung's Sure Win King once again starred during yesterday's Sha Tin trackwork session. Trackwork was unusually quiet last week, but there was more fast work to puzzle over yesterday, led by the highly-progressive three-year-old, who looks like developing into a really top horse. He ran second on his first two outings in Hong Kong, having won his only start in Australia, where none other than Ivan Allan was the under-bidder on him as a yearling. Those two defeats in Hong Kong can be attributed to age and distance. He was only a two-year-old when asked to give weight to older horses last season and the distance of 1,235 metres is on the short side for him. Pushed up to 1,400 metres last time out, he found a devastating burst of speed to win going away and the mile in tomorrow's feature Royal Hong Kong Golf Club Centenary Cup should suit him ideally. Yesterday, he looked in top condition for the Cup race when picking up off some very solid pace work to notch a final quarter in 24.2 seconds and complete a 1,200-metre workout in one minute and 16.3 seconds. His work and his form suggest he is going to be very hard to beat. Allan's In The Picture has also been working well for this event and, yesterday, his jumpout from the barriers with speedy stablemate All-Winners confirmed he must hold some kind of quinella chance. But then this is a tricky race for the quinella as Geoff Lane's Jacko was noted moving well in a recent trial, while there has also been good work from David Oughton's Quest For Gold and John Moore's Nervous Witness. Oughton's Classabove, a good winner of his last start over 1,235 metres at the Valley, is dropped back in distance for the 975-metre final event. This is a sprint where the top-weights look set to dominate and Classabove yesterday confirmed he goes into the race working as well as ever. He also jumped out yesterday morning when he always had the edge over his stablemate Strike It Hot who is fair worker, possessed of definite speed. In other jumpouts, Eddie Lo's Good Choice has reacted well to the fitting of blinkers and yesterday held stable-mates Lucky Sound and Charity Spirit down the back. Wong Tang-ping's Hammerhead has been working fluently since his win and is going to take plenty of beating in the third event tomorrow night.
