Learn How to Spot a Mate in 1: Queen Trap
This Vienna Game puzzle is a classic middlegame tactical shot where king safety matters more than material. White’s pieces look active, but the position contains a fatal weakness around the king and the back rank. The key lesson is that a hanging piece can be more than just a free capture: if the enemy king has no escape squares and the checking piece is protected, the game can end immediately. In classical chess, these direct threats often decide the game before any endgame begins.
