Lin Dan and Bao Chunlai will clash in the semi-finals of the Hong Kong Open today, just a week after meeting to decide the winner of China's City Games. Yet there might be more than just a place in the final at stake for the two 20-year-olds. With Chen Hong ranked number one in the world, and Xia Xuanze the reigning world champion, one of the pair would appear likely to lose out when China's three places in next year's Athens Olympics are held. At the moment Lin, from Xiamen in Fujien, has the upper hand, after beating Bao in Changsha. He's also risen to sixth in the world after winning the Danish Open and reaching the final of the German Open in September. The China Open in Guangzhou and the Hong Kong Open offer extra points because of their six-star status.
