Four Knights Game Epaulette Mate in Chess

The four knights game epaulette mate is a mating pattern that can arise from the Four Knights Game when Black’s king is boxed in by its own pieces on the back rank. The defining feature is a rook delivering mate along the first rank (often after the king is trapped by pawns/knights), with the king having no escape squares. In many lines, the setup is reached after typical Four Knights development (e.g., …Nf6 and …Nc6) followed by a back-rank lock that enables the epaulette mate.
