Learn How to Swallowtail Mate: Mate in 2
This puzzle is a classic middlegame mating net where the attacking side uses forcing checks to drag the king into a vulnerable square. The key idea is not material gain, but coordination: a rook and queen work together to overload the defender and expose the king. Patterns like this often appear in classical chess and tactical puzzles where king safety matters more than extra material. Once the defender is forced to respond, the final net becomes unavoidable.
