FIDE World Chess Championships (1998–2004)

The FIDE World Chess Championships from 1998 to 2004 followed a similar knockout format, radically different from previous World Chess Championship events. Previous events had had long qualifying cycles, spread over more than a year, culminating in a long match (best of 20 or 24 games) between the incumbent champion and a challenger. From 1998 to 2004, however, FIDE organised its World Championship as a single event over about a month, with many players playing short knockout matches, rather in the style of a tennis tournament such as Wimbledon.
