Learn How to Spot Mate in 2: Endgame Pattern
This chess endgame puzzle is a classic example of forcing play: the side to move uses a direct check to drag the king onto a vulnerable square, then finishes with a rook-supported mating net. The key idea is not material gain, but king safety and coordination. In positions like this, active pieces near the enemy king can outweigh everything else, especially when the king has few escape squares and the back rank or nearby files are weak.
