JOINT champion trainer John Moore had a great night out at Happy Valley last week and stable jockey John Marshall went home with a swing in his step after riding a double. Moore really hit his straps with a treble and the powerful stable now look to be getting right into stride. The Australian trainer saddles up Kwacha in the fourth event tonight with Marshall on board and there will be plenty of public support for the rising five-year-old. Moore is understandably happy with the way the season is going, saying: ''I did not aim to have or expect to have a flying start to the season. We were happy to get a few winners here and there and bring them on line as the season progressed. ''I have new horses coming in and you have to really plan things out for the whole season, not just the start of it. ''Obviously, it has been encouraging that we have had the winners so far and it tends to augur well for what lies ahead.'' While it was happy hunting for the stable at the city track last week, it could be slightly harder tonight - although Kwacha is an undeniable chance. He went under in the final couple of strides last time out to How Free, who came from well of the pace to score a fairly dramatic win for South African Jeff Lloyd. That was over 1,400 metres, so the Irish immport steps up 200 metres tonight - but has won over this trip previously. Marshall, who has been a real asset to local racing since his arrival over two seasons ago, thought he had just about won last time. ''He went well and, for a few strides in the last 50 metres, I thought we had it wrapped up. It wasn't just that he might have been feeling it, but the other one came home very strongly and we could not compete,'' said Marshall. But it could be a different story tonight. Kwacha now has the distinct benefit of that good run under his belt and the added distance tonight - at his second start - will mean he can be rated along by Marshall without the necessity of going for the addedpace necessary over a lesser trip. And, of course, Kwacha can run it out. He is a Class Three horse competing in lower company and a good number of winners have come from this particular ploy recently. But Kwacha will be right up against it when it comes to Ellen's Voyage, to be ridden by maximumm claimer W. M. Lai. Lai is undoubtedly worth his claim, which does bring Ellen's Voyage into a very attractive mark, considering his solid effort when just touched off last time out by Turf Apex. They came well clear of the third horse and, as it was Ellen's Voyage's first start of the season, there must be every reason to believe he has come on from that. He has done enough in his morning work since that run to certainly show he has not regressed. As both Kwacha and Ellen's Voyage like to be on the pace, it could make for interesting tactics tonight - with the vastly experience former Sydney champion Marshall clearly having the upper hand. Expect substantial support for Tony Cruz and Pleasant Surprise - and they can go close. Pleasant Surprise has also done well over this trip on equitrack and there was plenty to like about his first-up run when a fast-finishing third to Winning Wave and Partner over 1,400 metres. The form has not really be franked since, but, as Pleasant Surprise is an equitrack winner and Cruz has taken over from claimer Stanley K. M. Chin, he must be respected. Trainer Peter Tse Yan-sid, who happily got off the mark for the season last Wednesday when well-supported Beautiful Star obliged in the opener, has opted for a voluntary promotion with Joyful Delight, to be ridden by Dave Penna. The Toronto-based rider was aboard last time when Joyful Delight ran a solid second to hot-pot Hammerhead over 1,400 metres with 131 pounds on his back. The promotion brings the weight right down and Joyful Delight can give a sight although he is almost unknown at the distance. He did tackle it once midway through last season when finishing well back to Win Tack in a Class Four event. But his light weight tonight, plus his good recent run, suggests he might be worth considering as a tierce bet. Trainer Wyllie Wong has engaged Irish ace Mick Kinane for Wind Traveller and the duo put in a good final gallop on Monday. Wind Traveller campaigned on equitrack late last season, but over unsuitable short sprints. He has now come down into Class Three and has won in better company on two occasions over 1,400 metres. He has also placed at tonight's trip and should be accorded some respect. Of the rest, Success may have come on from his last run over 1,400 metres on the synthetic surface and Oriental Oilfield has been in fair form. But his equitrack form is ordinary and he has had a fair bit of racing in a relatively short period.
