Pirc Defense Kingside Attack Puzzle (Rated 920): Spot Mate in 2 — Kingside Attack

This middlegame puzzle is a classic example of a forcing kingside attack where the defender’s back rank and piece coordination collapse at once. White’s active rook placement creates immediate pressure on the enemy king, and the key idea is that the first forcing move drags a defender onto a square where it blocks escape and opens a direct mating line. In practical terms, this is a tactical refutation built on check, coordination, and a trapped king.
