Learn How to Win Material: Tactical Refutation
This middlegame puzzle comes from the Petrov's Defense and shows a classic tactical refutation based on piece activity and loose coordination. White has extra material, but Black can exploit the exposed queen and the vulnerable back rank to turn the game around. The key idea is to use forcing moves that improve rook activity, create threats against the queen, and punish the hanging piece before White can consolidate. It is a strong example of how initiative can outweigh static material.
