Learn How to Spot a Mate in 2: Kingside Attack
This puzzle is a classic middlegame mating pattern built around active rooks and a vulnerable king. Even though the material balance may look comfortable, the key idea is that open files can turn a seemingly stable position into a forced attack. When one rook can invade with tempo, the defender often has no time to coordinate. The lesson is to look for forcing moves first, especially checks that also create a direct mating net.
