Learn How to Spot a Mate in 2: Pin Tactics
This middlegame puzzle shows how a pinned piece can become the key to a forced mating net. White’s king is exposed, and Black’s queen and bishop coordinate to create a direct threat that cannot be met by normal defense. The important idea is that the first move is not just a check; it also restricts the king’s escape squares and overloads the defender. In classical chess, this kind of tactical refutation often appears when the opponent’s pieces are awkwardly placed.
