just saw him live. he always does a double action (forward-back-forward hit) on serve. i thought that was illegal, but it was never called by the service judge. checking the rule book: Once started, the service is delivered when the shuttle is hit by the server's racket or, in attempting to serve, the server misses the shuttle. am i missing something? any international/national umpire opinions appreciated PS. it wouldn't have made any difference the way the indonesians were playing.
to give you a quick short explanation, they say that the first "swing" was considered positioning of the racket so it is not considered a double action.
