Learn How to Spot Mate in 2: Swallowtail Mate
This chess endgame puzzle is a classic example of a forcing mating net built around king safety and piece activity. White’s queen and rook coordinate to exploit the exposed black king, while the defender’s heavy pieces are too passive to help. The key idea is that the king has very limited flight squares, so a checking move can drive it into a mating box. In classical chess, these short tactical finishes often come from active pieces overpowering material deficits.
