FIDE is an acronym for the Federation Internationale des Échecs, or World Chess Federation. It is a non-profit organization that was founded in 1924 and is based in Switzerland. The organization is responsible for organizing international chess tournaments, setting the rules of the game, and promoting the sport of chess. The two crossword solutions, MALA and BONA, are both Latin words meaning 'good' and 'BAD, ' respectively. This reflects the dual nature of FIDE, which is responsible for both promoting the sport of chess and regulating it.
