Melbourne Cup winning horseman David Hall should secure the most important win of his fledgling Hong Kong career when comeback galloper Beethoven rolls over from last week's good performance into today's $2 million HSBC Premier Plate (1,800m). Hall has made a great fist of the latest chapter of his life with horses, an opportunity gained through his winning the 2003 Melbourne Cup with the great mare Makybe Diva. However, there were no Makybe Diva equivalents awaiting him on his arrival at Sha Tin. Hall got the call-up as a replacement for retired three-time champion Ivan Allan but got little of the benefit because Allan anointed Danny Shum Chap-shing as his successor and most of his stable, including future Group One star Scintillation, went that way. Consequently, Hall had to graft his way through his first term with a lot of older, unsound horses. But today's Premier-class race, with Beethoven, should be a worthy reward for those initial struggles. Beethoven was originally trained by David Hayes and was, at one time, one of the most exciting horses in training. The handsome black son of champion sire Zabeel was considered a future star and at the peak of his powers ran a close fifth (three lengths) behind Lucky Owners in the 2004 Hong Kong Derby. Now a six-year-old, Beethoven has been worked back to peak fitness by Hall and his two runs from a spell have been excellent performances at the top of Class Two. On March 4, when having his first run since December 11, he ran with distinction for second to all-weather track star Stable Mail in a high-rating race, shouldering topweight of 133 pounds. Then last week, second-up from his time off, Beethoven ran third to course-and-distance specialist Agility, beaten by a head, this time under 132 pounds. Today, Beethoven is on a six-day back-up, giving him a big advantage over many rivals because of the benefits of race fitness. With the rise in grade - although formally a Premier, it's really just a glorified Class One - Beethoven takes a 14 pound weight drop. Beethoven showed his readiness for competition with a fluent, stylish 400m breeze on Thursday morning, with race rider Brett Prebble on board. Topweight Green Treasure will be aiming to do the hardest thing in Hong Kong racing - to win in Premier grade with 133 pounds. The last three horses to do it - Super Kid (twice), Electronic Unicorn and Fairy King Prawn - were all genuine Group One gallopers, underlining the enormity of the task. However, Green Treasure did show his class when second to Vengeance Of Rain in the International Cup Trial over 2,000m in November. And his riverside gallop under Weichong Marwing on Thursday suggests trainer Derek Cruz has him in grand order once again. Dennis Yip Chor-hong has gone for blinkers to trigger some improvement from his quality Danehill galloper Wealthy, already the winner of seven races and $4.7 million in prizemoney. In a 1,200m gallop with two lower-grade stablemates on Thursday, a blinkered Wealthy, ridden by race rider Howard Cheng Yue-tin, charged between his companions inside the final 200m and accelerated away stylishly. Wealthy's last run was a sixth of 14 runners behind Super Kid in the Hong Kong Gold Cup at weight-for-age. He may relish the return to handicap conditions here but with a rating of 112, the handicapper may well have caught up with him.
