Learn How to Spot a Mate in 4: Exposed King
This middlegame puzzle is a classic exposed-king tactical finish: the defending king is stuck in the center while the attacking pieces coordinate to force a mating net.

In classical chess, these attacks often begin with a forcing queen move that drags the king into a vulnerable square and opens lines for the rest of the pieces.
