Kateryna Lagno (White) Puzzle: Mate — Back Rank
A back rank mate occurs when a king is trapped by its own pawns or pieces and cannot create a flight square. In this position, Black’s heavy pieces coordinate along the kingside while White’s king is boxed in by nearby units. The attacking queen can exploit the weakened corner, supported by rook pressure on the file. This is a classic example of how king safety can outweigh material calculations in a tactical middlegame or chess endgame position.
