Also, in Fischer vs Spassky, after a series of wins by Fischer, soviet officials accused him of using eletronics to interfere with Spassky brainwaves.
So, were these fields it given credible scientific status, without some credible evidences, like some foresinc sciences are in the western world? Or was it more akin to some of the crazy CIA experiments of mind control? Or even yet, a well documented field of knowledge like phage therapy, that was ignored by the west due to it's association with the soviets?
Apparently, you are talking about Tofik Dadashev, Kasparov’s personal psychologist. Kasparov really appreciated this man and called him "my talisman". But first, I need to explain something about the Soviet 80s.
It all started with Eugenia Yuvashevna Davitashvili, known as Dzhuna. She was quite popular in Tbilisi as a psychic healer - many actors, artists and poets used her services. In 1980, Chairman of the Council of Ministers of the Georgian SSR Zurab Pataridze advised the head of the USSR State Planning Commission, Nikolai Baibakov, to invite Dzhuna to treat Baibakov's wife, whom official medicine could not help, and Dzhuna arrived in Moscow. By his power, Baibakov enlisted Dzhuna as an expert in a departmental clinic. On August 16, 1980, journalist Lev Kolodny published an article about her in the newspaper Komsomolskaya Pravda, after which Dzhuna became all-Union famous. She even was hired as a senior scientist at the Institute of Radio Engineering and Electronics. There was created a laboratory of "Physical fields of biological objects", which studied the "Dzhuna effect."
Dzhuna was examined in a physical laboratory with hypersensitive devices. Academician Eduard Kruglyakov, chairman of the Commission on the Fight against Pseudoscience and Falsification of Scientific Research, wrote about this examination: “You, of course, remember what the press wrote: Dzhuna could make the rose bloom with one movement of her hand, she could make a correct diagnosis from the photograph of the patient, move objects without touching them , etc. ... As it turned out, she was nothing more than a highly qualified masseuse. ”
The second half of the 80s was a time of Perestroika and Glasnost. Soviet media were looking for new ways to reach the audience and one consequence of this was the boom of psychics. Psychics became very popular; they gave interviews, predicted the future, arranged mass hypnosis, conducted television magic sessions and raised the dead. Some of them as Anatoly Kashpirovsky and Alan Chumak even got their own TV shows.
So back to your question. In 1987, Tofik Dadashev gave an interview to Literaturnaya Gazeta in which he stated that he was a psychic and made Kasparov a champion with the help of "special power emanating from him." In 1988, Dadashev organized the Parapsychological Assistance Center in Baku. The last interview with him dates back to 2010, where he predicts that there will be no European teams among the winners of the World Cup. (In fact, the first three places went to Spain, the Netherlands and Germany, respectively.)
In addition, I am afraid I have not found a reliable source, which states that soviet officials accused Fischer of using some device to interfere with Spassky brainwaves.
