Learn How to Force Mate in 3: Back Rank Mate
This chess endgame shows how a seemingly active defense can collapse when the king has no safe flight squares. The key idea is a forcing sequence: checks first, then a rook lift or rook invasion that removes the last defender and creates a mating net. Even with extra material, you must always calculate tactical threats before grabbing pawns or improving position. In classical chess, this kind of pattern often appears when rooks and knights coordinate against an exposed king.
