Learn How to Spot Swallow's Tail Mate: Mate in 1
This puzzle shows a classic mating net in the middlegame where the enemy king is exposed and key escape squares are controlled. The winning idea comes from coordinating the queen with supporting pieces so the king is boxed in with no legal flight. Patterns like this often appear when one side has active pieces, weakened king safety, and a loose defensive setup. In classical chess, these tactical refutations can end the game immediately even when material is otherwise balanced or favorable.
