Secretly fostered by JFK and teenage chess prodigy Bobby Fisher, the organization that began as the Complex High Energy Selective Surveillance group grew from a small but active department of the Secret Service into the premiere intelligence gathering and law enforcement agency in the United States. CHESS exists to assess the threat level of undocumented and unexplained superpowered activity, and when necessary to provide support to any superheroic response to such threats.
The hierarchy is organized along the lines of (you guessed it) a chessboard. Each rank corresponds to a particular piece, except that female CHESS agents have their own separate set of titles.
