CHAN Siu-kwong and Chung Hoi-yuk remain as Hong Kong's sole hopes of reaching the Grand Prix finals in Malaysia next month - but they must at least make the final of the Lipton Hong Kong Open to stand a chance of qualifying. The Hong Kong mixed doubles pair are currently ranked 10th in the world and national coach Diana Lo Leung Pik-luen is banking on them to carry the territory's colours in the end-of-season tournament. ''Only the top eight mixed teams will be featured in the Grand Prix finals and Chan Siu-kwong and Chung Hoi-yuk are our only hopes,'' said Lo. Chan and Chung are seeded third in the local event which starts today at the Queen Elizabeth Stadium, behind Indonesians Gunawan and Rosiana Tendean and China's Chen Xingdong and Sun Man. They kick off their campaign with a relatively easy first round match against Australia's Paul Staight and Michaela Wise. But their biggest test is likely to be in the semi-final when they are down to meet the top-seeded Indonesians. Chan said: ''We lost to Gunawan and Rosiana in Guangzhou last year but our teamwork has improved and it should be a closer match if we should meet in the semi-final. ''Anyway, we will be taking it one match at a time and we are looking no further than our first round tie against the Australians.'' Indonesia and China are expected to dominate the tournament which also features players from Denmark, Finland, India, Japan, Malaysia, Singapore, Taiwan and Thailand.
