FIDE World Chess Championship 1998

The FIDE World Chess Championship 1998 was contested in a match between the FIDE World Champion Anatoly Karpov and the challenger Viswanathan Anand. The match took place between 2 January and 9 January 1998 in Lausanne, Switzerland. The challenger was determined in a tournament held in Groningen, Netherlands, between 9 December and 30 December 1997. After the championship match ended in a draw, Karpov won the rapid playoff, becoming the 1998 FIDE World Chess Champion.

From 1948 to 1993, the world chess championship had been administered by FIDE, the international chess federation. In 1993, World Chess Champion Garry Kasparov split from FIDE and formed a rival organisation, the Professional Chess Association. FIDE stripped Kasparov of his title, meaning there were now two rival championships: the FIDE title, held by Anatoly Karpov, and the PCA title, held by Kasparov. Karpov and Kasparov had successfully defended their titles at the FIDE World Chess Championship 1996 and PCA World Chess Championship 1995 respectively.

From 1948 until 1996, World Chess Championships had followed a similar pattern: a series of qualifying tournaments and matches were held over more than a year, culminating in the Candidates Tournament. The winner of the Candidates tournament was the official challenger for the world title and would play the incumbent champion in a match for world championship. (The 1996 cycle was an exception. The incumbent world champion participated in the Candidates tournament as a seeded semi-finalist.)

In 1997, FIDE president Kirsan Ilyumzhinov proposed a completely new structure: a knockout tournament, consisting of two-game matches (slightly longer in the final rounds), with match tie-breakers using rapid chess and blitz chess if necessary. This format had been done before in tournaments such as Tilburg 1992-94, but never at the world championship level.
