Italian Game Rousseau Gambit Pin Intermediate Puzzle (Rated 989): Spot a Mate in 1 — Pin Tactic

This middlegame puzzle is a classic example of a forcing tactical finish. The key idea is that the enemy king is boxed in by its own pieces and the open lines around it create a direct mating net. In positions like this, a pinned piece can be especially important because it removes defensive resources and makes the final attack unavoidable. Always ask whether a checking move also attacks the king’s escape squares and blocks interposition.
