Crazy to claim that the match could have gone beyond 100 games. Fischer had been devastating in match play and strove to win with both colours. He often played out games to bare kings. Karpov became a great endgame technician but made his early name through fearsome opening preparation and Fischer's endgame was the best in the world by some margin. His energy at the board his biggest asset. Karpov too was not the drawing machine that he turned into. Shame it was not played and that Fischer got the fear, spoilt a great career.
Pfffft.
In 1978 against Korchnoi, Karpov had another close match, the final score was Karpov 6 wins, Korchnoi 5 wins and 21 draws. I believe Fischer would of won in 1978 too.
