INTERZONAL
Created by FIDE in 1947 with the aim to establish the man best qualified to challenge for the title. Participants were qualified through zonals or invited as leading rated world players. Usually the top five or six ranked of the tournament were qualified to the Candidate’s Tournament and later to the Candidates’s Matches. FIDE discontinued the tournament in 1993 but reinstalled it in 2007 under the name World Cup. Interzonal Tournaments (MEN)
