Learn How to Spot Mate in 1: Queen's Gambit Accepted
This puzzle comes from the Queen's Gambit Accepted and shows how a single tactical idea can end the game immediately. The position is a middlegame with active pieces, exposed kings, and a clear mating net around the enemy king. Even when material is equal, king safety can outweigh everything else. In classical chess, these one-move finishes often appear when a knight, bishop, or queen controls the key escape squares and the opponent’s pieces are too tied down to help.
