14th Indonesia National Championship, Denpasar 1973
The surprise winner of the event was Johny Suwuh of DKI Jakarta. He won ahead of more heralded players IM Ardiansyah, Arovah Bachtiar, and defending champion Jacobus Sampouw. Suwuh was not really a new face in the chess arena. He had been playing since 1960s but had never made a breakthrough until this event.
