World Title Candidate

Portisch's first Interzonal appearance was Stockholm 1962, where he tied for ninth/tenth places, after losing a late-round game to one of the tail-enders, and did not advance; the winner was Bobby Fischer. Portisch won the Halle Zonal 1963 with 14/19 to advance to the next Interzonal. Portisch qualified from the Amsterdam Interzonal 1964, with 14.5/23, in a tied eighth/ninth place (the winners were Mikhail Tal, Spassky, Vasily Smyslov, and Bent Larsen). Portisch defeated Samuel Reshevsky in a playoff match to advance to the Candidates' series for the first time, but he lost his first round match against Mikhail Tal at Bled 1965, by 2.5-5.5.

Portisch won the 1967 Halle Zonal with 15.5/19, to advance. He qualified through the Sousse Interzonal 1967, with 13.5/21 for a solo fifth-place finish. The winner was Bent Larsen.

Portisch and Smyslov played a drawn match (3-3) at Portorož 1971 for a reserve place, with Portisch declared the winner, as his tiebreak score from Palma was superior, though this proved unnecessary.

Portisch qualified from the Petropolis Interzonal 1973, scoring 11.5/17 for a shared second/fourth place (the winner was Henrique Mecking), then surviving a further three-man playoff for two berths against Lev Polugaevsky and Efim Geller, at Portorož 1973, by winning outright with 5.5/8; however, Portisch lost his first-round Candidates' match to Tigran Petrosian in 1974, by 6-7 at Palma de Mallorca. At the 1976 Biel Interzonal, he tied for second/fourth places on 12/19 with Petrosian and Tal, after Larsen.

Portisch got his revenge against Spassky in 1980, when he tied their quarterfinal match 7-7 in Mexico, and advanced to the semifinals since he had more victories with the Black pieces. He then lost the semi-final to Hübner by 4.5-6.5 at Abano Terme 1980. Qualifying from the Toluca Interzonal 1982, where he tied for first/second places on 8.5/13 along with Eugenio Torre, he lost his first-round match to Viktor Korchnoi by 3-6 at Bad Kissingen 1983.

Notable chess games

• Lajos Portisch vs László Szabó, Budapest 1958, Grunfeld Defence, Exchange Variation (D85), 1-0 The experienced Szabó, 20 years older, tries the unusual knight retreat to b6, perhaps hoping to confuse young Portisch, but it backfires.
• Lajos Portisch vs Svetozar Gligorić, Madrid Zonal 1960, King's Indian Defence, Orthodox Variation (E99), 1-0 In a very heavily analyzed line, one of the veteran Gligoric's favourites, Portisch proves he has the knowledge to prevail.
