Chagall could provide the key to tomorrow afternoon's feature event, the American Club Challenge Cup, as far as Triple Trio players are concerned. The David Oughton-trained gelding put in a tremendous run first time out this season when making up a stack of ground to run fourth to Sea Jade over 1,400 metres at Sha Tin. Chagall was only beaten three-quarters of a length and what made the run really good was that Wendyll Woods rode a most cunning and polished race on the winner. Sea Jade loves to lead. Chagall has to be ridden quietly and produced at the death. Woods had to work early on Sea Jade to get to the front but then he slowed them all down rounding the bottom bend before sprinting for home off the corner. That tactical brilliance by Woods won Sea Jade's connections the race and would not have helped Chagall's cause at all as the split times of 13.8, 21.7, 24.4 and 23.5 seconds testify. What they reveal is that Chagall ran an exceptionally fast final 400 metres as he was some lengths off Sea Jade who was the one that clocked that 23.5 seconds. There should be enough speed on for Chagall in tomorrow's contest as Charming Guest can take them along at a good clip. The track should also help Chagall into the placings and possibly even to victory. The new bend was in operation when he ran fourth to Sea Jade so he only had the shortened straight to run down. Tomorrow, racing is on the 'C' course and thus there is a longer home straight and more time for the ace French pilot Eric Saint-Martin to get Chagall into full stride. Pasha ran sixth in Sea Jade's race just 1.5 lengths behind Chagall and is a very similar case in point. He is best coming from off the pace and also when racing away from other horses. His was also a big run behind Sea Jade and now he is drawn out wide he should be able to burst home down the centre of the track and has to be one of the main fancies. Beas Glory also ran well when fifth to Sea Jade and comes into calculations as he didn't have the clearest of runs that night. Aipoder also looks very forward and his combination of trainer David Hayes and jockey Basil Marcus are in form. The top English rider, Brett Doyle, is a significant booking for the Derek Cruz-trained Ming River in the sixth event, the final leg of the Triple Trio. On his reappearance Ming River was poorly ridden by the stable's inexperienced apprentice behind Fit For Royalty. Ming River should have finished a lot closer than he did and had some very useful form for such a Class Six contest as this last term, notably when a solid second to King Star. Treasure Spring appears to have improved for Alex Wong Siu-tan and has to come into the reckoning while Flamme D'Or usually goes well at Sha Tin and Mr Belief appears to have been working exceptionally well. A word of caution about Mr Belief, though, he's a much better worker than he is a racehorse. Owners' Success and Sunflower look the other two main form picks for this low-grade contest. The third event, a Class Four 1,150-metre sprint on the dirt which opens the Triple Trio, is the toughest leg to get through. Third Time Lucky and Streak Of Dawn are both tremendous dirt performers in this grade and should go well. They appeal as the probable bankers. Keep the newcomer Full Energy safe, despite his lack of experience on the dirt, as he looks to have plenty of ability and will be winning very soon - if not tomorrow night. Pink Diamond is very much on the upgrade and Lickety Split has been working well and could dash home late into the placings.
