Learn How to Spot a Pin: Mate in 2
This middlegame puzzle is a classic example of how a pin can turn into a mating net. White’s king position is vulnerable, and the key idea is to use forcing checks to restrict the defender’s options. Once the first check lands, the reply is essentially forced, and the follow-up finishes the game immediately. In classical chess, these short combinations often appear when pieces are overloaded and the king has limited escape squares.
