Learn How to Mate in 2: Corner Mate
This middlegame puzzle is a classic mating net built around king safety, piece activity, and a forcing check on the open file. White’s rook invasion creates immediate pressure on the enemy king, while the knight is perfectly placed to support the final net. Even though Black is materially ahead, the exposed king and passive defenders make the position tactically lost. The key idea is to use forcing moves that leave the king with no useful escape squares.
