Rapport Jobava System Other Variations Pin Puzzle (Rated 1268): Spot a Pin — Mate in 2
This middlegame puzzle showcases how a pin can become a direct mating weapon. A valuable defending piece is restricted because moving it would expose the king, while the attacking queen and knight coordinate against vulnerable dark squares. The position also contains an advanced enemy pawn and loose pieces, but immediate king safety takes priority over material recovery. The key strategic lesson is that a pinned defender may appear to guard important squares while actually being unable to respond effectively.
