Mate In 2 Puzzle (Rated 575): Spot a Mate in 2 — Back Rank Trap

This puzzle is a classic forcing sequence where the attacking side uses check, capture, and a final rook invasion to finish the game. The key idea is that the defending king is boxed in by its own pieces, so even a seemingly active queen can become a tactical liability. In middlegame positions like this, look for loose pieces, open files, and direct access to the king before considering slower strategic plans.
