TOP local rider Jackie C. K. Tse could well hold the key to the outcome of the second leg of the Double Trio at Happy Valley's Martell Grand National meeting on Saturday night. Tse rides handy sprinter Bogie's Pride in the fifth event on the card, highlighted by the simulcast transmission of the Aintree spectacular. Bogie's Pride looks an ideal banker as he is returning to the city course where he scored in very solid fashion on his Hong Kong debut early in the season. Bogie's Pride is a very useful sprinter and his current form is certainly sound enough as he chased home Chiu Chow Warrior at his last start. That was over the longer Sha Tin sprint on March 20 and though he went under by a length-and-a-quarter there wascertainly no disgrace in that defeat as the winner is a very good type who was turned out to perfection that day by trainer Neville Begg. It is his current form plus his obvious liking for the city track that makes Bogie's Pride an ideal banker in a tricky Class Two longer sprint. He was tried over longer at Sha Tin and backed down to a short quote two starts back but did not oblige and connections have rightly decided to restrict him to these longer sprints. Bogie's Pride has drawn out in barrier nine but it is not such an inconvenience at the 1,235-metre start as the outside horses virtually run straight into the 975-metre bend and may not have to go off much off a straight line to get a good position. Joint champion trainer John Moore has two involved here with senior rider John Marshall partnering Parkview Fame and apprentice Victor C. F. Chan going on to Django who failed here over the minimum trip at his last start. The riding tactics will be interesting as this longer sprint definitely suits Django much better and if he is not ridden on the pace but allowed to come from behind under Chan, he could well be a major threat. Parkview Fame is limited but fast. However, he will have to work quite hard from an extreme outside draw and Parkview Fame has not always impressed in the past as being entirely resolute. Sun Crest is dropped back in distance from 1,650 metres where he ran an honest second to Feodor last time out and is not without claims here. The first leg of the DT is a Class Four event over 1,800 metres and both Iron Horse and the David Hill-trained Gladstonian make appeal. Iron Horse is competing here under the overlap system and despite the 139 lbs he must be a very realistic chance for former apprentice Jimmy K. H. Ting who rode such a good race on bottomweight Ocean Pride to win the final event at Sha Tin on Saturday. Iron Horse is very dangerously placed in this grade and he was not that far away at his last run when finishing fifth to Feodor over 1,600 metres at Sha Tin on March 13. He was two lengths off Highland Laddie who ran a very solid race behind Ocean Pride last weekend. Gladstonian was ridden to perfection by apprentice Raymond S. M. Tam, course and distance, on February 16. He was also badly drawn on that occasion but Tam made no mistakes and got him up to beat Berkut with a big gap back to third-placed Radiant Sun. It's a tall order but the gut feeling must be that Gladstonian has still room for improvement and that a win in Class Four is within his scope. He has unquestionably held his form since his last start win and will definitely give a good sight here.
