Double Bishop Mate Puzzle: Double-Bishop — Mate
A double-bishop mate is a mating pattern in which two bishops—or a bishop working with another attacking piece—control the king’s escape squares while a decisive check lands. The key strategic idea is coordination: one piece restricts flight squares, another attacks the king directly, and defensive pieces may be pinned or trapped. In this position, Black’s queen and bishop dominate the king zone, while White’s cramped knight and weakened pawn shield make the mating net impossible to escape.
