Alexey Sarana (Black) Puzzle: Mate — Bishop & Knight
This chess endgame demonstrates the power of coordinated minor pieces around an exposed king. A bishop controls key diagonals while a knight can cover escape squares, creating a compact mating net. Black’s active rook, bishop, and knight already exert strong king-zone pressure, while White’s centralized king has limited safe squares. The tactical opportunity comes from recognizing how one forcing check can combine the bishop’s line control with the knight’s support to deliver a clean mate in 1.
