South Korea's controversial Thomas Cup ploy paid off when they eased into the badminton tournament's quarter-finals by outclassing Canada 3-0 in a playoff in Djarkarta.
The Koreans now meet Denmark having avoided a possible clash at this stage with China or the hosts Indonesia by fielding a weakened team that lost group games to England and Malaysia.
The Badminton World Federation is considering introducing a new format to prevent a repetition.
But its deputy president Punch Gunalan says no rule has been broken and he doesn't blame the Koreans.
They say their strategy's always been to face the European champions Denmark in the quarter-finals, Indonesia in the semis and China in the final.
In other quarter-final action tonight the holders China play Thailand, Indonesia meet England and Malaysia face Japan.
