INDONESIA arrived yesterday, light-hearted and bubbling with confidence that they can beat Hong Kong again in only the second Davis Cup tie between the teams in 21 years, writes Norideen Kitchell. Indonesia thrashed Hong Kong 5-0 way back in 1973 when neither of their two likely singles players for this tie - Benny Wijaya and Suwandi - were born. Their other two members are Bonit Wiryawan and Donny Susetyo. ''There wasn't any special preparation for this match and we've only trained together for two weeks because everybody has been away playing tennis,'' said non-playing captain Wailan Walalangi. ''We don't feel any pressure and the players are not nervous because they travel around playing tennis a lot and are very experienced.'' Wijaya, ranked 290th, is Indonesia's number one and the other singles berth will be handed to 17-year-old Suwandi, who defeated Filipino star Felix Barrientos in winning the SEA Games gold last year.
