Learn How to Mate in 1: Rook Sacrifice
This middlegame puzzle is a classic example of a direct mating attack where a single forcing move ends the game immediately. White’s heavy pieces are lined up against the black king, and the key idea is that the defender on the e-file is overloaded by the pressure on the king. When a rook can invade an open file with tempo, it can turn a seemingly normal position into a forced checkmate. The tactic combines king safety, piece activity, and a hanging piece motif.
