ONE-TIME Derby candidate Flirting Dancer ran a fine race first-up for his new trainer John Moore and could follow up on that by running boldly in the first leg of the Double Trio at tomorrow's entertaining Sha Tin meeting. Flirting Dancer had been off the scene for some time before switching to Moore from Patrick Biancone and his debut outing for his new stable saw him run a slashing third to Thunder Bolt and Mr Judge over 1,600 metres at Sha Tin on March 26. Flirting Dancer has unquestionably come on from that run and Thunder Bolt franked the form significantly with a particularly game winning effort last Saturday. Mr Judge, too, ran a bold race at the same meeting. Flirting Dancer has been slightly disappointing overall - or certainly in the context of the high hopes that were held out for him. He won in spectacular fashion for Mick Kinane early this season but failed to reproduce that form, making Derby hopes look far-fetched. But his last run again revealed the promise that excited observers in his griffin year and he is worth taking as the banker for the first leg of the Double Trio. The gelding does face formidable opposition, however. Topweight Accelerating ran his best race when finishing fourth last Saturday and the Geoff Lane stable is in scintillating form at the moment. The Australian trainer has taken the chance and backed up his costly Irish import who comes into this Class Two race on the overlap system. Accelerating has Irish form in Listed and Group company and his encouraging run last time suggests he may now be coming to himself in Hong Kong and is worth putting in as a DT leg. Another potentially exciting Irish import is David Hill's Amza Glory who will be ridden by Eric Legrix, happily back in action after a six-meeting suspension. Amza Glory ran pleasingly on his debut over 1,400 metres behind Fukien Boy when badly drawn and apprentice-ridden. He was closing swiftly at the finish and will relish the step up in distance. However, the ''second up'' syndrome is almost a feature of local racing with private purchase horses and it may still pay to be slightly wary with Amza Glory although, on his first run, it is impossible to leave him out. There's not much at the bottom of the handicap here to threaten but Sagar did not have a lot of luck in running last time at the Valley and might be better suited by the switch to Sha Tin. The featured Sassoon Challenge Cup is the second leg of the exotic bet and plenty of attention will be focused on the Neville Begg-trained Winning Partners who is Tokyo-bound next month for an important invitation race. Clearly on his International Bowl form the horse has a great chance to win here over the 1,200 metres of the feature event but there is just a niggling doubt about how well he has really been going in his work for the race. Concert King ran a better trial recently but Compradore ran like a horse that was going over the top at his last start at Happy Valley. Trainer Hill has engaged Darren Gauci for Red Ruffian and he went particularly well in a piece of work with River Verdon early this week and looks to be coming right back to form. Gauci looks an ideal partner for the horse and punters could do worse than take a slight chance and put the Chairman's Prize winner in as the banker. The English sprinter has had his problems this season with cracked heels but is over that - and he is also back to a distance that would seem to suit him better. Derby winner Super Fit also drops back to this trip and former hero Quicken Away makes his re-appearance. Both may have it to do.
