Learn How to Mate in 2: Back Rank Mate
This middlegame puzzle is a classic example of a forcing mating net built around king safety and overloaded defenders. White’s heavy pieces coordinate to attack the enemy king’s shelter, while the opponent’s queen and minor piece are tied down by defensive duties. The key idea is that one forcing check can drag the king into a vulnerable square, where the follow-up finishes the game. In classical chess, these patterns often appear when the back rank and h-file are weakened.
