Learn How to Discover Checkmate: Mate in 4
This puzzle is a classic mating net built around a forcing queen sacrifice and a discovered attack on the king. The key idea is to remove the defender so the rook can join the attack with tempo, while the bishop and queen coordinate to restrict escape squares. Even though the position looks materially balanced for White, king safety is the real story: Black’s pieces are already active near the white king, and one precise tactical sequence turns that pressure into a forced finish.
