One of these things is not like the others
Please go to the Question #19 post if you haven't had a chance work on this one yet, since the text below contains the solution.
The french is a bit of a red herring here. "En passant" ("in passing")is a term in chess which refers to special pawn capture. "J'Adoube" (or "I adjust") is something a chess player would say if they want to adjust the position of a piece on the board, and not actually make a move. And FIDE stands for Fédération Internationale des Échecs -- The World Chess Federation.
The remaining term has nothing to do with chess. "Touché" is a term in fencing used to acknowledge a hit. It is not like the others, so it does not belong.
