Learn How to Win Material: Deflection
This puzzle is a classic forcing sequence where material count matters less than king safety and coordination. White uses a queen sacrifice to drag the defending king onto a vulnerable square, then follows with a rook invasion that removes the key defender. The position shows how a long middlegame can suddenly become tactical when the enemy king is boxed in and pieces are overloaded. It is a strong example of advantage attraction and deflection working together in classical chess.
