Learn How to Deflection: Mate in 3
This middlegame puzzle comes from the Scandinavian Defense and shows how a single forcing check can collapse a king’s shelter. White’s queen and bishop coordinate against the black king, while Black’s back rank and overloaded defenders leave little room to breathe. The key idea is deflection: forcing a defender away from a critical square so the final mating net becomes unavoidable. In classical chess, these patterns often appear when the enemy king is boxed in and the heavy pieces are tied down.
