Learn How to Mate in 2: Back Rank Mate
This middlegame puzzle comes from the Ruy Lopez and shows how king safety can outweigh material. White’s queen and rook are already active around the enemy king, but Black’s position contains a hidden tactical resource based on the exposed king and weak back rank. The key idea is to recognize when a forcing check can drag the king into a worse square, allowing a follow-up mate. In classical chess, these patterns often appear when development is lagging and the king remains in the center.
