Hong Kong start their squash campaign today hoping they can return with two medals from the women's event. While Rebecca Chiu Wing-yin's expected showdown against Nicol David of Malaysia in the final would be the highlight of the competition, Christina Mak Pui-hin is also hoping for a breakthrough in her international career. 'Mak has been working very hard for the Asian Games and this is her best opportunity to clinch a medal at a major games,' said coach Tony Choi Yuk-kwan. 'She has a favourable draw and it is now up to her to deliver.' Mak will take on little-known Chan Si-man of Macau today, and if she goes through, she is expected to meet Mami Nishio of Japan. Chiu, the defending champion, will not start until tomorrow when she meets Wu Zhenzhen of China, a player who has been training at the Hong Kong Sports Institute. 'The mainlander should hardly pose Chiu any threat,' said Choi. In the men's event, Wong Wai-hang will meet Qatar's Abdulrahman Al Malki in today's first round. 'It will be a tough battle for Wong, but you cannot expect any easy game at this level,' said Choi.
