The chessboard lies silent as still as a mirror, but beneath its ancient wooden frame, a battle rages in secret. The two Crimson Chariots stand guard across the fifth file, like two mighty mountains blocking the Black Cannon's arrows. The Black General steps into the open, exposed in his position, while the Crimson General hides behind his sturdy fortress wall. This is not just a formation - it is a masterpiece of attack and defense, where each piece is a stroke of genius in the tactical canvas. Will the Crimson break through the Black Cannon's wall, or will the Black turn this formation into a 'siege of the capital' drama?
