In chess there is a beautiful (and quite rare) mating pattern - the Epaulette mate.
Epaulette (from French epaulette) is a shoulder rank insignia in the form of a decorative patch or shoulder board that was and continues to be used in military uniforms of many countries.
Originally epaulettes appeared in France in the 18th century and had a practical purpose - they protected shoulders from saber strikes. Later they became an important element of military uniforms indicating rank and branch of service.
In chess the Epaulette mate is a checkmate where the King has its own identical pieces "on the shoulders" (more precisely - on both sides). Most often these are pawns or rooks. These pieces represent the epaulettes on the board. Unfortunately they don't protect the King but prevent him from escaping the opponent's piece's attack and as a result the King is checkmated. The King must be on the edge of the board (Diagram 1). If the king is not on the edge of the board - then this mate is not an epaulette mate.
