Learn How to Swallowtail Mate: Mate in 2
This puzzle is a classic middlegame mating net where the attacking queen dominates the enemy king’s escape squares. The key idea is not material gain, but forcing the king into a cramped box and using coordination between queen and bishop to deliver a final mating pattern. In classical chess, these short tactical finishes often appear when king safety is the dominant imbalance and the defender’s pieces are overloaded or poorly placed.
