Learn How to Corner Mate: Mate in 3

This chess puzzle shows a classic corner mate pattern in a middlegame setting. The attacking side uses active rook placement and king safety pressure to force the enemy king toward the edge, where escape squares disappear. Even though material may be balanced or favorable, the real story is the mating net: checks are coordinated so the defender cannot safely interpose, capture, or run. In classical chess, these patterns often appear when the king is boxed in by its own pieces and pawns.
