'There's nothing like riding good horses - it's something a jockey can't explain to someone who doesn't ride' Brett Prebble has an amazing knack of being in the right place at the right time, and that intuitive gift saw him snatch yesterday's $3 million Chairman's Trophy on Bullish Luck ($36.50) to add to his rapidly expanding list of big-race exploits in Hong Kong. Prebble happily filled the role of understudy to Tony Cruz's stable jockey Felix Coetzee, who agonised for days over his choice of two horses from the stable and ultimately went for favourite Perfect Partner. And that's when Cruz called on Prebble, who had landed the Hong Kong-Macau Trophy for the leading trainer last month on Helene Pillaging. The two-time champion Melbourne jockey had, in fact, previously been booked for Elegant Fashion, who had won the Group Two race 12 months earlier. Prebble is a man who honours his bookings, but the offer to ride the Group One Stewards' Cup winner was just too tempting. 'I've got to thank David Hayes,' a buoyant Prebble said after the race. 'I was taken off Ain't Here [on whom he had won the International Cup Trial in November] and put on Elegant Fashion, but he let me off her to ride Bullish Luck. 'To my way of thinking, the best two horses in Hong Kong from this group are Ain't Here and Bullish Luck and I think Bullish Luck definitely has an edge on Ain't Here. 'The difference is in their finishing runs. Ain't Here can run 22.5 seconds for his final 400 metres, he just can't go any faster than that but it would win most races. Bullish Luck can run 21 and change, and he sustains his finish longer than Ain't Here.' Prebble has now won four Group races in Hong Kong, as well as the $2.3 million interport feature, not to mention last month's Group One Australia Stakes on Cape Of Good Hope. His reputation as a big-occasion rider is already substantial and growing by the week. 'There's nothing like riding good horses - it's something a jockey can't explain to someone who doesn't ride,' Prebble said. 'And this is a good horse. In the run, I was happy but not as confident as I have been in some big races - that was as much as anything because I didn't know the horse.' Bullish Luck had swooped from the tail of the field to finish fifth to Perfect Partner in the Hong Kong Gold Cup on February 20 but, while beaten by the pace factor, still ran an astonishing 21.3 seconds for his final 400m. Mortal thoroughbreds do not go any faster. Yesterday, with the Caspar Fownes-trained Saturn setting fast splits, Bullish Luck remained in last place to the turn before unleashing his blinding turn of finishing speed, and the 2005 Chairman's Trophy was over in a heartbeat. Ultimately Bullish Luck hit the line with 13/4 lengths to spare over Ain't Here, with Prebble giving a jumbo-sized celebratory gesture that began before they'd reached the winning post and lasted the best part of 125m. While Prebble was having a one-man party in the saddle, Bullish Luck shifted in slightly and caused Ain't Here to crowd Elegant Fashion, earning him an audience with the stewards. 'Brett Prebble was reprimanded for that and he agreed with us that it was a bit over the top, he should have taken more care,' chief steward Jamie Stier said. The John Size-trained High Intelligent backed up bravely from last Sunday's Derby to run third under Michael Rodd, narrowly in front of his stablemate Super Kid (Douglas Whyte), who loomed up to win the race but didn't stretch out fully on the firmer ground. Cruz maintained his incredibly consistent season, fielding two winners, a second and a third from seven runners. He and Coetzee had earlier combined to win the opening event for griffins with $12.50 favourite Lucky Unicorn. Cruz has now moved to 63 wins, 20 clear of defending champion John Size, and is on course to obliterate every Hong Kong training record.
