Learn How to Mate in 3: Rook Sacrifice
This puzzle is a forcing middlegame combination built around king safety and piece coordination. White’s rook activity on the open file creates immediate pressure, and the key idea is to use a sacrifice to drag the defender away from the king’s shelter. Once the first defender is removed, the remaining pieces can no longer cover the critical entry squares. Patterns like this often appear in classical chess and are a good reminder that active rooks can outweigh material when the enemy king is exposed.
