Nuclear Debate will bid to make it third time lucky in the Sprint after dismal failures in the past two seasons, but even his new connections are uncertain about his chances. The former European champion sprinter, who was purchased recently to join Darrell Vienna's Californian stable for more than $2 million, has had only one run in the US and that did not shed much light on his form. Assistant trainer Victor Tovar explained: 'The race was over 1,000 metres round a bend and the jockey was told to cover him up until the stretch and then come out for a run. But, instead, he brought him six wide and the horse came up empty at the end. It was pilot error, not trainer error, but it means we're still not sure what he can do.' Gary Stevens will take over the reins on the six-year-old, who breezed on the grass yesterday, and Tovar added: 'He seems well, but the fast ground may not be in his favour. We know he's not done well here in the past, but we're hoping for the best. If Gary can get him settled, he should run well.' While the international stars are galloping their way past the morning bacon and eggs and the watchful eyes at the Sha Tin training track this week, hometown hero Electronic Unicorn is going quietly about his business in the quiet and darkness. Electronic Unicorn was one of the early gallopers on the all-weather track yesterday morning in his Hong Kong Mile preparation. Away from the fuss, he carved out 1,000 metres in 56.7 seconds and came home to the line in 23.4 seconds, with trainer John Size aboard. 'That's his usual type of work and he did it in his usual fashion,' Size said. 'I'm not changing anything with him - it would be a bit late in the day to be doing that.' Australian pair Shogun Lodge and Show A Heart have more than pleased their connections with their grass workouts and their condition ahead of the Hong Kong Mile. Jockey Glen Boss said Show A Heart had 'worked even better than I would have expected' after his gallop on Tuesday and the triple Group One winner is due to have another searching gallop tomorrow. 'He's a great traveller so I knew the trip over wouldn't worry him. He's doing well here,' said trainer Barry Miller yesterday. Race jockey Shane Dye was again aboard Shogun Lodge for a solid 800-metre hitout yesterday and his trainer Bob Thomsen said the gelding was right where he wanted him. 'We'll see what happens in the next 48 hours, but he might not need another gallop on Friday,' said Thomsen, who has been here previously with Shogun Lodge, Majestic Boy - who was third in the 1991 Hong Kong Cup - and Silk Ali (sixth in the 1993 Cup). 'He lost about 10 kilos between running at Rosehill and arriving here after the flight from Sydney through Melbourne, but he has put that back on since he has been here. He is about 560 kilograms [1,260 pounds] and that's his racing weight. It can be tricky here sometimes because the horses sweat up in the humidity, but Shogun Lodge has been OK so far.' John Ridley received an unlikely inquiry following his light-hearted comment in Tuesday's Post that the Sha Tin course was too good to race on this Sunday and more in keeping with a golf green. 'I got a call from Shane Templeton, the greenkeeper at Fanling golf course, who said he was on his way over with his putter to test out my theory,' the Jockey Club's track manager laughed yesterday. Ridley added that the outlook for the rest of the week was for cloudy but fine weather. 'It will be fairly cool, but we don't expect any significant rain and on Sunday we're hoping the temperature may go up into the low 20s.' Andreas Suborics, who will begin his first stint as a Club jockey after Sunday's races, is hoping for a flying start aboard Silvano in the Hong Kong Cup. After partnering the Audemars Piguet QEII Cup winner in a routine canter, the Austrian-born jockey said yesterday: 'I'm happy with the horse. He looks well to me and he is moving well and I think he is in the same sort of form he has been all season. 'He hasn't run a bad race all year, and in Australia last year he was just a little short of peak fitness, but still was there with a chance on the home turn before he got tired.'
