Cazorla, Spain, hosted the World Chess Council WCC
(following the PCA, following the GMA; these organisations were in concurrence to the FIDE during the time of the schism) World Chess Championship Candidates Final Match in 1998 between Kramnik and Shirov to determine the right to challenge
Kasparov. Despite being the underdog, Shirov won with 5.5-3.5 (two wins, no loss!).
However, things went wrong for the nominated Challenger Shirov, instead, it was Kramnik who got a shot for the
title, dethroning reigning Champion Kasparov:
Between 1993 and 2006, the title was split during the schism, there always have been two rivaling international chess bodies (FIDE and GMA / PCA / WCC, then FIDE and Braingames / Einstein) and both arranged World Chess Championships
and crowned World Chess Champions..
