World Correspondence Chess Championship
The World Correspondence Chess Championship determines the World Champion in correspondence chess. Men and women of any age are eligible to contest the title. The official World Correspondence Chess Championship is managed by the International Correspondence Chess Federation.
The world championship comprises four stages: Preliminaries, Semi-Finals, Candidates' Tournament, and Final. ICCF tournament rules define which players can access each stage. The first-, second- and third-placed finishers from the previous Final, and the first- and second-placed finishers from the Candidates' Tournaments have access to the World Correspondence Chess Championship Final.
