Learn How to Spot Swallowtail Mate: Mate in 2
This puzzle is a classic middlegame mating net where the attacking queen uses a forcing check to drag the king into a cramped square. The key idea is that the defender’s pieces and king are already poorly coordinated, so one tactical shot creates an immediate mating pattern. In practical classical chess, these positions often arise when a hanging piece near the king becomes the trigger for a direct attack, especially when the enemy king lacks safe flight squares.
