Geller, Korchnoi, Spassky, and Petrosian are pictured
Korchnoi's teammates in various team competitions cover no less than seven undisputed World Chess Champions:
Karpov, Spassky, Petrosian, Tal, Smyslov, Botvinnik,
and Euwe (with Volmac Rotterdam).
Note: Euwe (1901-1981) and Korchnoi played 1979 in the same team at the 2nd European Chess Club Cup (held decentralised):
Of course, Viktor Korchnoi faced most of the mentioned players also as opponent in national and / or international team events, ie. Botvinnik in 1960, December (Moscow vs. Leningrad, Korchnoi beat Botvinnik 1.5-0.5) or then reigning World Champion
Petrosian in 1965 (Moscow vs. Leningrad, Korchnoi beat Petrosian without mercy 2-0).
Korchnoi also faced Kasparov three times in direct encounters during team tournaments:
> 1982 in Lucerne at the Chess Olympiad (USSR
vs. Switzerland, Karpov taking a rest his second round in a row, a famous win for young Garry as replacement on board one)
> 1988 in Madrid at the 3rd USSR vs. REST OF THE WORLD Match, Rapid in Scheveningen System. Korchnoi and Kasparov
drew their indivual game, they were the only players to remained unbeaten in an elite field, Korchnoi, by far the oldest player, scored the individual best performance of all:
