20 years ago: Anand and Karpov fight for the World Championship

Twenty years ago this week, on January 2, 1998, Viswanathan Anand and Anatoly Karpov began their match for the FIDE World Championship in Lausanne, Switzerland — under peculiar circumstances. Anand had qualified for the match by winning the knock-out tournament in Groningen but then had to go immediately to Lausanne to play for the title — without a break or time for preparation.
