Peligroso Patzer: Here is some information about the denouement of this game from the following site: http://www.mark-weeks.com/chess/78k...:
"As game 8 was about to start, Korchnoi was left with his hand in midair when Karpov refused to shake with him -- 'Never! Never will I shake hands with you!" Roshal explained during the next press conference, 'Recent events have shown that the Challenger has not reduced his line of intensifying tensions and under such circumstances Karpov does not wish to shake hands with Korchnoi.'"
"In response to Karpov's refusal to shake hands, Korchnoi started insisting that the players should not speak to each other. Draws could only be offered through the arbiter. Karpov refused to go along with this, considering the complications this could bring in time scrambles. His point was proven during the match.
"As the players were about to adjourn game 12, Karpov offered a draw directly to Korchnoi. Korchnoi indicated with a nod that he should go through Schmid, but Karpov shrugged his shoulders and left the playing area. After sealing his move, Korchnoi gave the envelope to Schmid and complained about Karpov's direct offer of a draw. Schmid misunderstood and thought that Korchnoi was offering a draw. He relayed the offer to Karpov, who accepted it the next day. When Schmid announced to Korchnoi that his draw offer had been accepted, Korchnoi was very surprised, but agreed with the result to avoid embarrassing Schmid."
