Learn How to Spot Corner Mate: Mate in 1
This puzzle is a classic corner mate pattern from the Queen's Gambit Declined, where king safety is the deciding factor. Even with material level, one side’s king is boxed in by its own pieces and pawns, creating a tactical finish in a single move. In classical chess and middlegame play, these motifs often appear when an active knight or queen controls key escape squares and the opponent’s king has no flight squares left.
