Viktor Korchnoi played four times and won twice at Hastings, at his very first participation in 1955/56 shared with Fridrik Olafsson (Island) ahead of Borislav Ivkov (Yugoslavia), followed
by Mark Taimanov (USSR) and at his second participation in 1970/71 together with Anatoly Karpov (USSR) - with Korchnoi winning their direct encounter - ahead of brazilian prodigy Henrique Mecking, shared together with Robert Byrne (USA), followed by Svetozar
Gligoric (Yugoslavia) and Miguel Najdorf (Argentina).
In 1975/76, Korchnoi was fourth behind the three joint winners David Bronstein (USSR), Vlastimil Hort (CSR), and Wolfgang Uhlmann (GDR), ahead of Mark Taimanov (USSR), with a bunch of young
and promising brits competing for the first english origin grandmaster title, among them Tony Miles, who won that race, Keene, Stean, Nunn and Hartston. In 1988/89, Viktor Korchnoi was runner-up behind Nigel Short (England), ahead of shared
third Jonathan Speelman (England), Boris Gulko (then USA, emigrated from USSR), Vasily Smyslov (USSR), and followed by Bent Larsen (Denmark).
Viktor Korchnoi earned
the grandmaster title by FIDE after winning Hastings in 1955/56, it was his very first individual chess tournament abroad eastern countries and only the second individual tournament abroad after being clear first at Bucharest in 1954, subsequently
earning the IM title. There was no ELO metrics, and the grandmaster title, in its inauguration 1950 donated to 27 players (half of them due to historical achievements), was restricted to absolute elite players, until the 1970s there were far less
than 100 Chess Grandmasters worldwide alive.
This event is by far the longest major recurring international classical chess tournament in annually tradition still existing.
