''IT'S not over until the fat lady sings,'' was David Hill's championship summary after a double at Wednesday night's final Happy Valley meeting of the season took him into a share of the lead with John Moore. They are followed by Lawrie Fownes, Ivan Allan and Derek Cruz who have two, four and four winners respectively to pick up on the leaders and are following exactly the same never-say-die attitude as Hill. Yesterday Fownes was in fighting spirits at the track. The former champion trainer of Calcutta has performed wonders to hang on in there against the likes of Hill, Moore and Allan who all have full complements of horses. Fownes has a good few vacant boxes but they would begin to fill rapidly should he be able to pinch the championship from his rivals. He looks to have three good chances with the likes of Super Fit in the Sha Tin Vase, The Winning Way in the third event and Crown Commander in the seventh probably being the pick of them though Money No Problem has plummeted down the weights and cannot be ruled out of the fifth. Yesterday Fownes said: ''For me the Sha Tin Vase looks to be out of Super Fit and Dashing. My fellow goes into the race really well in himself and I'm hopeful of a bold showing. ''There is this talk that Dashing may not handle a badly rain-affected track. Well maybe it's true. He is a very big sort. ''Mine should be able to handle the wet as he's an entirely different type. He's a smaller, compact individual. ''I can't see any reason why he won't go in the wet, but I am worried about Dashing.'' The Winning Way has been a difficult horse to train due to leg problems and Fownes went on: ''He comes into the race that much fitter but he is still green and a bit of a baby during the run. That is my main worry. ''I would respect the chances of My Bunny in this race as he loved the wet last time and also of Always Luck who also likes the ground.'' As for Crown Commander, Fownes conceded that he had dropped a couple of pounds in the ratings and struck a relatively uncompetitive event for this time of year. ''The one I'm most worried about is Tony P. H. Chan's horse, Fortune Ride, as he really distanced them when going straight to the front on the yielding ground last time. ''He has gone up a fair bit in the ratings for that win but he clearly goes well on the ground and is the improving horse.'' There was one trial on the main equitrack yesterday. It went to Cruz's Jarnac who has seldom worked better. He was ridden by Darren Beadman who after the trial reported himself very pleased with Jarnac's effort. Alex Wong Siu-tan's American Eagle took second a length and a half behind Jarnac having led until the final 200 metres. He is one to keep on hold and reassess after next season's trackwork has developed into full swing. Third home came Allan's French import Gomile who was putting in by far his best piece of work of the season. Allan had a number of horses out yesterday having pipe-openers and he is clearly not giving up on the title until it is mathematically impossible for him to win. Yesterday Gomile went better the farther they went in this 1,150-metre heat. He had to be pushed along in the middle stages but he was hard on the bit and travelling strongly to the line over the last 200 metres.
