Promoting to a rook, bishop, or knight instead of a queen because the lesser piece is best.
Where the term comes from
Promoting to anything other than a queen is rare enough that it is worth learning the two cases where it wins: a knight for an immediate fork or mate, and a rook to avoid stalemate. The Saavedra position of 1895 — where only a rook wins — is the most famous example in all of chess composition.
