Learn How to Spot Mate in 1: Opera Mate
This middlegame puzzle is a classic example of a mating net where the enemy king has very few safe squares and the final blow comes from a rook on the open file.

Even if one side is materially ahead, a single tactical shot can end the game immediately when the back rank and escape squares are controlled.
