Learn How to Spot Swallowtail Mate: Queen Endgame
This puzzle is a classic queen endgame mating net where the attacking queen uses checks to force the enemy king into a boxed-in square. The key idea is that the king’s escape squares are already restricted by its own pieces and pawns, so a forcing move can drive it into a final mating pattern. In classical chess, these short tactical finishes often decide seemingly equal endgames because king activity and queen coordination matter more than material.
