Learn How to Clear the Defender: Mate in 4
This puzzle is a classic clearance and sacrifice pattern in a sharp middlegame that quickly turns into a forced mating net. White’s queen and rook coordinate against the black king’s shelter, and the key idea is to remove the defender that guards the escape squares. Once that defender is lured away, the remaining pieces can invade with forcing checks. In classical chess, these patterns often appear when king safety is the dominant imbalance.
