Center Game Queenside Attack Beginner Puzzle (Rated 983): Spot Pillsbury's Mate — Mate in 2

This puzzle is a classic middlegame mating pattern where White uses active piece placement to exploit the enemy king’s limited escape squares. The key idea is that a forcing check draws the king into a vulnerable line, allowing a rook to deliver the final blow. Patterns like this often appear when the defender’s back rank and nearby squares are overloaded, and one well-timed tactical move can turn a material edge into immediate checkmate.
