The Jakarta result was Berger's best of his career. He tied for first on 5.5/8, and then won the playoff against Indonesia's Arovah Bachtiar. (He won the playoff 2-1 after 3 games; a fourth game was won by Bachtiar, but it had no bearing on the outcome, as the tiebreak system used favoured Berger). The win gave him the title of International Master, and qualified him for the Interzonal of the 1964-66 World Championship cycle.
