Viktor Korchnoi
The 1978 Karpov–Korchnoi World Championship match was held in Baguio, Philippines. It was one of those events where the struggle took place off as well as on the board. Korchnoi's status as a defector and stateless person was exploited to the full by the Soviet delegation. Karpov's team was a dozen strong, and only three of them were chess players. They included Dr Zukhar, Karpov's personal psychiatrist/psychologist, whom (it was claimed) attempted to hypnotise Korchnoi during play.
