Learn How to Discover Checkmate: Mating Net
This puzzle is a classic middlegame mating net where a discovered attack and discovered check combine to end the game immediately. White’s king is exposed to a bishop-led strike, and the key idea is that one piece can move to reveal a direct line of attack on the king. These patterns often appear when the defender’s king is boxed in by its own pieces and pawns, leaving no flight squares or useful interpositions.
