Portoroz Interzonal Playoff 1973
Compiled by Tabanus
--*--

Henrique Mecking won the Petropolis Interzonal (1973) with Portisch, Polugaevsky and Geller in a shared second place. But only three players from Petropolis could go to the candidates matches (in 1974), and a playoff was necessary. It took place in Portoroz, Yugoslavia (Slovenia) in September. The ultimate goal was to select a challenger for Robert James Fischer, the World Champion.

The Hungarian Portisch started the four-way round robin with a disadvantage, as he had the lowest Sonneborn-Berger score in the interzonal. In the event of a three-way tie, or a tie for second place, he would be eliminated. His two rivals were also of the same nationality. The suggestion was made that the order of games be arranged so that the Soviet masters would always play each other first. Portisch protested. He trusted his opponents’ sportsmanship and with reason: during the course of the play Geller and Polugaevsky won against each other in turn.1 In Geller vs Portisch, 1973, Geller (who had better SB score in the interzonal) erroneously marked the time control on the score sheet at move 84, and lost on time.2

Portoroz YUG 5-21 September 1973

Elo 1234 1234 1234 Pts 1 GM Portisch 2650 **** 11˝˝ ˝1˝˝ 5˝ 2 GM Polugaevsky 2625 00˝˝ **** 110˝ 3˝ 3 GM Geller 2605 ˝0˝˝ 001˝ **** 3

So Geller was eliminated. Mecking, Portisch and Polugaevsky joined Anatoly Karpov, Viktor Korchnoi and Robert Eugene Byrne from the Leningrad Interzonal (1973) for play against Tigran Vartanovich Petrosian (qualified as losing finalist in 1971) and Boris Spassky (qualified as ex-World Champion in 1972) in the next year's matches:

Spassky - Byrne Candidates Quarterfinal (1974)
Petrosian - Portisch Candidates Quarterfinal (1974) Karpov - Polugaevsky Candidates Quarterfinal (1974) Korchnoi - Mecking Candidates Quarterfinal (1974)

None of the players from Petropolis reached the semifinals.
