Double Bishop Mate Puzzle: Double Bishop — Mate

A double-bishop mate relies on coordination rather than material advantage. One bishop typically delivers the checking attack while the other controls escape squares, creating a compact mating net around the king. In this chess endgame, Black’s bishops are active in the king zone, and White’s centralized king has limited shelter. The key tactical idea is to notice how the bishops work across contrasting diagonals, restricting movement until the king has no legal defense.
