{ Fischer challenged world champion Boris Spassky. Many problems occurred until
the match began in Reykjavik. FIDE President Euwe had a hard time. When Jim
Slater doubled the prize money of $125,000 and Henry Kissinger phoned Bobby,
Fischer finally flew to Iceland. It had become a confrontation between
capitalism and communism. Public interest for the mad genius was enormous.
Spassky was respected, because he had a score of +3, =2 against Fischer.  The
'match of the century' started on 11 vii 1972 with the usual time limit of 40
moves in 2 1/2 hours. An audience of 2300 spectators followed game one in the
Laugersdalholl stadium. } 1. d4 Nf6 2. c4 e6 3. Nf3 d5 4. Nc3 Bb4 5. e3 O-O 6. Bd3 c5 7. O-O Nc6 8. a3 Ba5 9. Ne2 dxc4 10. Bxc4 Bb6 11. dxc5 Qxd1 12. Rxd1 Bxc5 13. b4 Be7 14. Bb2 Bd7 15.

Spassky.  The real Bobby had great plans for his future activities. Little
resulted from his high ideals. A rematch took place after twenty years.

{ The official world championship of Fischer would last three years. Thereafter,
the Soviet players dominated the chess world again. The new world champions
would become Karpov and Kasparov. Anatoly Karpov was the ideal chess champ for
the Brezhnev period: 1. The little man from Leningrad was a devoted communist,
like Botvinnik. 2. His prophylactic play led to many victories and few losses.
  On his way to the top, Tolya met a strong opponent in the semifinal of the
candidates' matches, the former world champion Boris Spassky. } 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 e6 6. Be2 Be7 7. O-O O-O 8. f4 Nc6 9. Be3 e5 10. Nb3 a5 11. a4 Nb4 12. Bf3 $6 Be6 13.
