HONG KONG'S world number three Chai Po-wa crashed out of the World Championships here yesterday when she lost 17-21, 21-19, 21-14, 21-14 to Xu Jing of Taiwan in the third round. Third-seeded Chai had beaten Xu in the team competition but had lost to the 30th-ranked former mainland Chinese competitor in earlier meetings. The territory's team manager David Cheng said: 'They were quite evenly matched. It was down to who played better on the night and the Taiwanese performed to a higher level. It was disappointing but she [Chai] was very tired after the Commonwealth Championships and the team event.' Hong Kong's other top woman player Chan Tan-lui, singles bronze medallist at the 1991 world championships, is looking forward to her fourth-round match with China's number two seed Qiao Hong at the World Championships today. Chan, seeded 16th, cruised into the last 16 with a 21-13, 21-12, 21-11 destruction of Slovakia's Zuzana Poliackova yesterday to set up a crack at the mercurial Qiao. Beijing-born Chan, who has represented Hong Kong for more than six years, has beaten Qiao four times in their 10 meetings at major competitions and she is not writing off her chances this time. 'She is a very strong player but I have a good record against her,' said Chan, a previous top-10 player whose world ranking has slipped to number 21. 'I beat her in the final of the 1989 Japan Open and again in the semi-finals of the China Open so I know I can do it. 'I have not really worked out what tactics I will use - I'll think about that tonight. 'I am quite confident about playing her and will do my best to win.' Qiao and Deng Yaping formed the backbone of the China team who won the women's title on Sunday but her form has been up and down, giving Chan reason for hope. Chan and Chai, seeded to repeat their bronze medal effort of two years ago, have reached the third round of the women's doubles where they will play Bettine Vriesekoop and Mirjam Hooman of the Netherlands. But Chai and Lo Chuen-tsung's interest in the mixed doubles ended when they went down 21-16, 21-16 to Erik Lindh and Maria Svensson of Sweden. Lo and Chan Kong-wah also exited the men's doubles, losing to Slovenia's Robert Smrekar and Gregor Komac. Thirty-four-year-old Chan was still suffering a reaction from his efforts on Wednesday night when he came within a game of knocking defending champion Jean-Philippe Gatien out of the singles. Chan led the Frenchman by two games before being overwhelmed by Gatien's famous spin returns to go down 22-24, 14-21, 21-9, 21-8, 21-10. 'In the first two games he had trouble returning my serve and I also tried to keep the ball low over the net so he could not use his spin so effectively,' said Chan, who beat world number one Jean-Michel Saive, of Belguim, in the team competition. 'But he is a great player and he changed his tactics after going two down and started to force me away from the table which allowed him to put in more spin returns.'
