Learn How to Force Mate in 3: Rook Sacrifice
This chess puzzle is a classic forcing finish in a sharp middlegame-to-endgame transition. White’s heavy pieces are coordinated to attack the black king, and the key idea is to use a rook sacrifice to drag the defender away from the back rank and open a direct mating net. The position rewards precise calculation, because the winning line is not about winning material first — it is about forcing the king into a helpless square and converting activity into checkmate.
