Petrovs Defense Cozio Attack Puzzle (Rated 1018): Deflect — Winning a Rook

This middlegame puzzle is a classic example of deflection: White uses a forcing check to pull the black king away from its shelter, exposing a key defender and creating a decisive material gain. The position features active white pieces, a vulnerable black king, and a trapped rook on the open file. In classical chess, these tactical moments often come from king safety and piece coordination rather than a direct attack on the king itself.
