Learn How to Spot Corner Mate: Mate in 1
This puzzle is a classic middlegame mating net where the enemy king is boxed in by its own pieces and the final blow comes from a knight jump into the corner zone. The key idea is that checkmate can appear even when material is heavily imbalanced, because king safety overrides everything. In positions like this, a single forcing move can end the game immediately if the king has no escape squares and no piece can capture or block the attack.
