World Chess Championship 1978 on a stamp of the Philippines

The 1978 World Chess Championship was played between Anatoly Karpov and Viktor Korchnoi in Baguio, Philippines, from July 18 to October 18, 1978. Karpov won, thereby retaining the title.

The match had many bizarre incidents. Karpov's team included noted Soviet psychologist and hypnotherapist Vladimir Petrovich Zukhar, while Korchnoi enlisted the help of two American Ananda Marga yoga specialists who had recently been convicted of attempted murder and released on bail. There was more controversy off the board, with histrionics ranging from X-raying of chairs, protests about the flags used on the board and Korchnoi's complaints that Zukhar, sitting in the front row, attempted to hypnotise him. 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.

In quality of play, the match itself never measured up to the press headlines that it generated, although as a sporting contest it had its share of excitement. The match would go to the first player to win six games, draws not counting. After 17 games, Karpov had a 4–1 lead. Korchnoi won game 21, but Karpov won game 27, putting him on the brink of victory with a 5–2 lead. Korchnoi fought back, scoring three wins and one draw in the next four games, to equalise the match at 5–5 after 31 games. However, Karpov won the very next game, and the match, by 6–5 with 21 draws.

1976 Interzonal tournaments

Two interzonal tournaments were held in 1976 in Manila and Biel, with the top 3 from each qualifying for the Candidates Tournament.

1977 Candidates tournament

As loser of the last championship (by forfeiture) and runner-up of the previous Candidates tournament, respectively, Bobby Fischer and Korchnoi were seeded directly into the tournament. When Fischer declined, Spassky, as losing semifinalist of the previous tournament, was offered the spot. The two seeded players were joined by the top three from each of the two interzonals. Viktor Korchnoi, formerly a representative of the USSR, was stateless at the time and played under the FIDE flag during this cycle.

Remarks: This Nimzo-Indian Defense led to a grueling Bishop endgame spanning 124 moves and finally ending in the stalemating of Black (see Stalemate#Korchnoi versus Karpov). Korchnoi later explained that since he could not beat Karpov, he would simply stalemate him, adding that it gave him great pleasure to do this to the world champion. The game was adjourned twice. Korchnoi overlooked a checkmate-in-7 on move 55. This was the longest game to feature in a World Chess Championship final, until Game 6 of the World Chess Championship 2021, a 136-move win for Magnus Carlsen (White).

Remarks: Karpov makes an ill-considered exchange on move 41, leaving him with an isolated rook that is useless in fending off Black's queen and bishop which allowed Korchnoi to equalize the score.

Remarks: Korchnoi got into a dispute with the organizers before the game, which led to him making his first move with over 10 minutes already gone on his clock. He still managed to build up a winning position, but stubborn defense by Karpov together with time trouble for Korchnoi eventually led to a series of blunders and his advantage evaporated. Korchnoi's last move, 39. Ra1, was a blunder that allowed Karpov a forced mate where the two knights push the white King into a corner checkmate. Korchnoi needed to play 39. g3, which would have led to a drawn position.
