Interzonal tournaments
Interzonal chess tournaments were tournaments organized by the World Chess Federation FIDE from the 1950s to the 1990s. They were a stage in the triennial World Chess Championship cycle and were held after the Zonal tournaments, and before the Candidates Tournament. Since 2005, the Chess World Cup has filled a similar role.
