Learn How to Spot a Pin: Mate in 1
This middlegame puzzle is a classic example of how a pinned defender can turn a normal-looking position into a forced finish. White’s heavy pieces are active, the black king is exposed, and the key defensive piece is overloaded by the king’s safety. When a rook or queen controls the escape squares and the back line is weakened, a direct tactical shot can end the game immediately. The lesson is to always check for checks first, especially when the enemy king has few safe squares.
