The Red Chariot on File 5 Rank 9 attacks directly at the Black General on File 4 Rank 8. The Red Cannon on File 2 Rank 5 and the Red Pawn on File 3 Rank 6 apply pressure, while the Black Chariot on File 4 Rank 7 and the Black Cannon on File 1 Rank 3 must defend carefully. Lessons in double horse exchanges and rapid counterattacks.
