Red utilizes a hidden Elephant to coordinate with Cannon and Chariot, creating an overwhelming attack that forces Black's King into a mating net.
This position highlights the power of hidden piece coordination. Red's Elephant, positioned deep within Black's territory, is poised to support the Cannon and Chariot. Black's critical weakness lies in their isolated King and lack of defensive support. The endgame lesson here is to leverage hidden pieces for surprise and pressure, while always maintaining the safety of one's own King.
