Learn How to Spot a Mate in 3: Mating Net
This middlegame puzzle is a classic example of how king safety can outweigh material. White’s position looks materially healthy, but the king is exposed and the back rank is fragile. Black’s pieces coordinate to create a mating net, using a forcing sacrifice to drag the king into a worse square. The key idea is not just winning a piece, but removing defenders and limiting escape squares until checkmate becomes unavoidable.
