Learn How to Spot a Mating Net: Back Rank Mate
This middlegame puzzle comes from the Semi-Slav Defense and shows how a strong attack can override a large material deficit. White’s king is exposed, the dark squares around it are weakened, and Black’s queen and minor pieces coordinate to create a forcing mating net. The key idea is that checks can be more powerful than material when the enemy king has limited escape squares and defensive pieces are overloaded or trapped.
