The 27th Hoogovens tournament returned to Beverwijk with another sixteen-player round-robin. Soviet grandmaster Efim Geller and Hungary's Lajos Portisch — the latter a fixture near the top of these events — shared first on 10½/15, with Bulgaria's Milko Bobotsov a single half-point behind them.
A tight grandmaster group
By 1965 the Hoogovens steelworks tournament had settled into its role as a leading January meeting on the international calendar, held in Beverwijk as a single round-robin of sixteen players. The field brought together Geller and Portisch, Bobotsov, Borislav Ivkov, Heinz Lehmann, Vladimir Bagirov, Svein Johannessen, Ludek Pachman and Aleksandar Matanović, with Jan Hein Donner and Kick Langeweg leading the Dutch contingent.
The race was close throughout the upper half of the table. Geller and Portisch finished level on 10½; Bobotsov pressed them all the way to 10, and only then did the field fall away, with Donner and Ivkov the next best on 8½.
