Learn How to Mate in 2: Rook Sacrifice
This chess endgame is a classic forcing pattern where active rook play overwhelms the enemy king. The key idea is to use a sacrifice to drag the king onto a vulnerable square, then deliver a second rook check that ends the game immediately. In classical chess, these short tactical finishes often come from coordination, open files, and a king with too little shelter. Recognizing the mating net is more important than counting material.
