Learn How to Spot Mate in 1: English Opening Tactic
This puzzle comes from the English Opening and shows how quickly an apparently normal middlegame can collapse when the king is still unsafe. The key idea is a direct mating attack against the exposed king, with the queen using open lines and weak squares to deliver immediate checkmate. In classical chess, these one-move finishes often appear when development is lagging and a tactical target is left undefended.
