THE big guns came out blazing on the Sha Tin turf yesterday morning in the most revealing trackwork morning of the season. Ivan Allan was as good as his word. He let everyone know that he was intending to work potential champion Mr Vitality through a serious 1,200 metres in company with a stablemate and he did just that. The ironic thing about the workout was that while Mr Vitality certainly went well enough he was, to some extent, upstaged by his galloping companion, the admirable Sterling Town who relished the easy conditions underfoot. Mr Vitality is never a flashy worker and he did just shade Sterling Town as Basil Marcus drove him right out to the line. But Sterling Town was coming back at him all the time in the final 100 metres and it should pay to keep a close eye on this seasoned Class One handicapper the next time he runs. Allan actually has him in the first division of the Classes One and Two 1,400-metre handicap on Saturday and while that could well be a bit short for him, he really is on good terms with himself and may handle the longer sprint while he is still relatively fresh. Mr Vitality is testing Allan's training skill to the full. Or rather the race programming is testing Allan as there just aren't the races available for this Australian import who is unbeaten in four starts in the territory. Allan is setting him for the Stewards' Cup on November 11 and clearly has to put some very serious work into him if he is going to be fit enough to take on the best milers in training first time out at level weights. This is not Allan's usual style of training by any means but he is forced to cut his cloth according to the programme book. Normally Allan would be letting his horses come to peak condition via a more gentle mixture of racing and trackwork. Patrick Biancone's hopes for the future, Deauville and the AJC Derby fourth Gazebo Star, worked together on the grass. Neither was put under any pressure and it was hard to split them. Interestingly, Biancone has already reached for the blinkers for Gazebo Star who wore them when showing his best form in Australia. Veteran handler Neville Begg made use of the grass to work three of his best horses, Winning Partners, Deerfield and Auto-Matching. They all enjoyed solo spins. Deerfield has progressed since his promising reappearance and I'm tempted to say that Winning Partners has never gone better, at least not since his triumph in the International Bowl. He is flying. So, too, is the Stephen Leung-trained Lickety Split who held stablemate Make Merry in a solid workout on the main all-weather surface. There was also one trial on the dirt. It was won in most emphatic fashion by the Lawrie Fownes-trained Super Fit who went clear under Jimmy Fortune. The Club Jockey has picked up a tremendous spare ride for Saturday's big race, the Panasonic Cup, as stable jockey Lance O'Sullivan appears committed to China Cruise who went well enough on the grass in readiness for the weekend's feature event, as did David Oughton's Jade Age. First trial 1, SUPER FIT (J. Fortune); 2, Star Lap (K. M. Chin); 3, Karamour (S. M. Tam). Others (in finishing order): Lucky Lord, Super Class, Win Label, Zambezi, Chung San, Daring Hawk, Cold Killer. Time: 1.00.8 (23.6). Distances: 9 lenghts, 4 lenghts. Winner trained by Lawrie Fownes.
