Learn How to Spot a Corner Mate: Mate in 1
This middlegame puzzle shows a classic king-safety collapse where the defender’s pieces and pawns no longer protect the king’s escape squares. The key idea is a corner mate pattern: the attacking knight lands on a square that delivers immediate checkmate because the king is boxed in by its own pieces and the board edge. In classical chess, these motifs often appear after a kingside attack when one loose piece or weak pawn creates a fatal tactical net.
