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 active on the g-file, and the black king has limited escape squares because its own pawns and pieces restrict flight. The key idea is to use a forcing check that drags the king into a worse square, then finish with a direct mate pattern. In classical chess, these short tactical finishes often appear when the defender is overloaded and the king is exposed.
