Learn How to Mate in 3: King Safety
This middlegame puzzle is a classic king-safety lesson: one side’s pieces are coordinated to force the enemy king into a narrow box.

Here, the vulnerable king is exposed to a forcing sequence where every reply is limited, and the final blow comes from a direct queen-and-bishop collaboration.
