The match of 1978 deserves its reputation as the most bizarre World Championship match ever played. Karpov's team included a Dr. Zukhar (a well known hypnotist), while Korchnoi adopted two local renegades currently on bail for attempted murder.[1] There was more controversy off the board, with histrionics ranging from X-raying of chairs, protests about the flags used on the board, the inevitable hypnotism complaints and the mirror glasses used by Korchnoi. When Karpov's team sent him a blueberry yogurt during a game without any request for one by Karpov, the Korchnoi team protested, claiming it could be some kind of code. They later said this was intended as a parody of earlier protests, but it was taken seriously at the time.[2]

Before you think this is just another long boring pointless troll thread, it's not long.
The secret is hypnotism. No joke, if you are playing someone who sits there transfixed you will win on time. Someone could try out OTB and let me know.
