Learn How to Spot Corner Mate: Mate in 1
This puzzle is a classic corner mate pattern from the Queen's Gambit Declined, where the king is boxed in by its own pieces and pawns. Even in a middlegame, a single tactical shot can end the game immediately if the enemy king has no flight squares and the checking piece lands on a protected square. These positions reward pattern recognition more than calculation, especially when development and king safety are sharply imbalanced.
