Wet-track performers will be all the rage on the eight-race card at Happy Valley tonight and Our Class, who won on a yielding track in his native New Zealand, fits the bill perfectly in the featured Happy Valley Vase. Tony Cruz's three-year-old gelding came within a whisker of winning the Sha Tin Vase last time at odds of 24-1, a highly creditable display in by far his toughest test to date. In two outings prior to that, the speedy chestnut had performed creditably at Happy Valley over tonight's 1,170-metre trip after drawing awkwardly, a factor which certainly cost him victory on his penultimate start. With the powerful South African rider Felix Coetzee back on board this evening, as well as the advantage of gate five, he should take all the beating. Derek Cruz's Solid Contact can handle any conditions and the consistent son of Snippets will be suited by the move back to 1,170 metres after failing over a mile last time. The concern tonight is that he has to concede weight all round, and he is likely to start quite short in the market. He has a great chance to make the frame again, but there may be better value around. Red Zone and The King Of Cloyne will be suited if the poor weather continues, and both have winning form over course and distance. Bruce Hutchison's Red Zone typically settles at the rear of the field and the ageing son of Fairy King should be suited by a likely fast pace to be set by Expedient, Our Class and Ovation. He should also be suited by a move back to a sprint trip after performing fairly over the Valley mile on his last two outings. Peter Chapple-Hyam's The King Of Cloyne has had his share of problems, and that may be why he prefers a little give in the ground. His effort behind Meridian Star two starts back when beaten a length was on a good to yielding track, and on that occasion he may have been tested by the 1,400 metres. A good barrier and light weight tonight should see him fighting out the finish. Expedient has drawn ideally in gate one and will prove hard to catch out on the lead. It will depend just how much pressure is applied by Ovation and Our Class, who both like to race prominently. Lawrie Fownes' Ovation is a winner of three races this term, but his form has dropped away in the latter part of the season. His wide barrier does not improve his chances. Ivan Allan's Crystal Charm has not won since November 1999, and the mare is not quite the force she used to be. However, this is an easier field and, while she may need further relief in the handicap, her sheer class could take her into a minor placing. Stylish is going to struggle from a wide gate, and being a son of Rory's Jester will not be suited if the track is rain affected, while Hornet is likely to find this distance too short. Bruce Hutchison's My Chief is the leading chance in the final event on the programme over 1,170 metres. He has not ventured back to his pet course and distance since winning the Australian Centenary Cup back in January, but that race should prove a valuable form pointer with four of tonight's 11 rivals having competed in that event - Delightful Special, Flamenco Star, My Honour and Beas Glory. My Chief has only been beaten over this course and distance once this season, and that was a short-head loss to Ace Academy. The key for My Chief is that he needs a solid tempo, which does look possible in this event with Success Magic and Flamenco Star likely to ensure a genuine pace. Derek Cruz's My Honour was beaten 2.75 lengths in the Australian Centenary Cup, but he has risen in the handicap since with a blistering win on his last start and actually meets My Chief four pounds worse for that defeat. He is, however, still improving and should be considered one of the main dangers. Alex Wong Siu-tan's Flamenco Star also won his last start under a well-rated front-running ride from Tony Culhane, who keeps the ride tonight. The gelding's well-being gives him a chance to make the frame. Hardest to beat could be Ricky Yiu Poon-fie's Victory Marble, who should get the run of the race from gate five under Robbie Fradd. He, too, will appreciate the move back to Happy Valley and can handle any ease in the ground.
