Philidor Defense Epaulette Mate Chess Puzzles

Philidor defense epaulette mate is a mating pattern that can arise in the Philidor Defense when the black king is boxed in by its own pieces, often with rooks or other pieces blocking the escape squares on the back rank. The key feature is an epaulette setup: the king is trapped on both sides by friendly pieces, so a checking piece delivers mate because the king has no legal flight squares.
