Learn How to Spot Swallowtail Mate: Mate in 1
This puzzle is a classic middlegame mating pattern from the Vienna Game: the attack lands because the king’s shelter has been stripped away and the defending pieces are overloaded. Even when one side is materially better, king safety can override everything. The key idea is to look for direct checks on the king’s weak squares, especially when major pieces and bishops coordinate to cut off escape routes. In tactical terms, this is a forcing finish, not a slow positional squeeze.
