Learn How to Spot: Mate in 1
This middlegame puzzle is a classic example of a mating net built from active pieces and an exposed king. White’s bishop and knight coordinate to exploit dark-square weaknesses around the enemy king, while Black’s pieces are too clumsy to create counterplay. The key idea is to recognize when a forcing move ends the game immediately because the king has no safe escape squares and no piece can capture the attacker or interpose effectively.
