IM Ardiansyah edged out Fabian Lumentut on a better Solkoff to grab number one spot. Defending champion Denny Juswanto found himself at 8th.
The Indonesian first GM, Herman Suradiradja, was anonymous most of the time. Losing to unheralded players like Hengky Wijaya was simply unacceptable for a player of his stature.
