Many of the events are based on the Anatoli Karpov vs Viktor Korchnoi World Chess Championship match in 1978. The actual match pitted Karpov (a Soviet prodigy) vs Korchnoi (who had escaped to the West just a few years prior to the match), and there was no love lost between the sides. The accusations included Karpov's team using a "parapsychologist" (Vladimir P. Zukhar) to sit in the audience and try and unnerve Korchnoi during the matches, and Korchnoi using two members of the Ananda Marga sect who were experts in "transcendental meditation". Other actions included arguments about what anthems and flags could be used, accusations of secret devices hidden in Korchoi's chair that he used during the matches (the chair had to be X-rayed), and accusations that yogurt delivery to Karpov during the games was a form of secret communication. The events are also described in the documentary Closing Gambit: Korchnoi vs Karpov & The Kremlin (2018).
