The "Seeded into Final" column usually refers to the incumbent champion, but this has a different meaning for the World Chess Championship 1948, in which five players were seeded into the championship tournament, the Classical World Chess Championship 2000 in which two players were seeded into the championship final, the FIDE World Chess Championship 2005 in which eight players were seeded into the final championship tournament, and the FIDE World Chess Championship 2007, in which four players were seeded into the final championship tournament.
