Learn How to Mate in 2: Back Rank Mate
This middlegame puzzle is a classic example of a mating net built around king safety and piece coordination. White’s heavy pieces are already active near the enemy king, and the key idea is to use a forcing check to drag the king onto a vulnerable square. In positions like this, material counts less than the geometry of the king’s escape squares. The tactical finish comes from a direct attack on the back rank and the limited mobility of the black king.
