1981.10.24-29. Team. Round Robin 7 rounds. 8 teams. 4 main players and 2 reserves for each team.
The event was only possible because of the synergy between Percasi (All Indonesia Chess Federation), in the city and provincial levels, and the Probolinggo city government. The major of the city, R Djoewito Moeljodisastro, showed his office’s full support to the event. He said in the opening ceremony that chess would be an important part of the development of the young generation in the city.
Eight teams from cities/regencies of East Java province battled for Percasi Cup. As predicted the pre-tournament favorite Surabaya team won the cup. The only team who gave them a fierce challenge was Jember. Jember and Surabaya had the same VP 19.5. Unfortunately Jember had lower MP, 5, compared to Surabaya’s 6.5. Jember had national class players in Rudy Indra and Billah but Surabaya was more balanced team.
Surabaya’s third board player Machfud was the sensation of this event. He excelled from the rest of pack by scoring 100%, 7 VP from 7 games.
