THE pressure will be on Tim He Yiming when the former Chinese international leaves for Europe today in a last-ditch effort to consolidate Hong Kong's position in the badminton event at the Atlanta Olympic Games. He holds to key to Hong Kong's qualification for Atlanta - hovering at the cut-off mark in both the men's doubles and mixed doubles events. The doubles specialist and Chan Siu-kwong are 20th on the men's doubles world rankings and would qualify for Atlanta if they can hang on to their placing by March 31. And He is 18th in mixed doubles with Chan Oi-ni, just one place outside the cut-off mark for the Olympic Games. The precarious positions of the two combinations have forced national coach Chan Chi-choi to interrupt Hong Kong's Thomas Cup and Uber Cup preparation and enter them for the Swiss Open and All England Championships. He and Chan Siu-kwong, who have made a meteoric rise from 77th position at the beginning of 1995, will only play in the Swiss Open while the mixed pair will compete in both tournaments. Said Chan Chi-choi: 'I must admit we are in a desperate position and we must drop everything to try and ensure the Hong Kong flag will be flying in the badminton arena in Atlanta. 'It's a make-or-break situation sending them to Switzerland and England because we could end up qualifying in both events or not making it to Atlanta at all.' Coach Chan, however, is confident that the men's combination can make the cut by reaching the quarter-finals in Switzerland although they would still have a chance by making the last 16. But the mixed pair must at the very least reach one quarter-final to make any reasonable advancement on the world rankings.
