The chessboard is trembling like a battle between light and darkness. Red opens with a rook on 5th rank, 7th file, igniting an unstoppable invasion. This formation is not just an attack but a *bloody strategy*, where both sides must choose between sacrifice and victory. Black, with a horse on 4th rank, 8th file and a cannon on 6th rank, 10th file, faces a dangerous dilemma: "Refuse the attack to protect the general or dare to accept the death of a soldier to expand the formation? Explore the hidden schemes in every move of both sides."
