The Classical World Chess Championship 1993, held in London from September 7 to October 21, saw Garry Kasparov defend his title against Nigel Short. Organized independently by the newly formed Professional Chess Association (PCA) following a split with FIDE, the 20-game match ended in a dominant 12.5–7.5 victory for Kasparov. His blend of strategic depth and tactical ingenuity secured his continued reign as world champion. This championship marked the start of the division between the Classical and FIDE titles, a split that persisted until the reunification in 2006.
