Learn How to Win a Queen: Crushing Fork
This middlegame puzzle shows a classic tactical refutation in the Mexican Defense: White uses an active queen check to force the black king and bishop into an awkward response, then wins the hanging queen-side piece. The key idea is that a checking move can also be a fork or a deflection tool when the opponent’s pieces are overloaded. Here, king safety is the dominant imbalance, so activity matters more than static material.
