17th Indonesia National Championship, Jakarta1976
The 17th Indonesia National Chess Championship introduced many new faces. IM Ardiansyah, Jacobus Sampouw, and Arovah Bachtiar still sat down on top but Monang Sinulingga, Ridwan Gozali, Mukmin Panggabean, MHS Nainggolan, Abdul Azis Riduan, and the other usual suspects were nowhere to be found in the big 20.
