◇ Just read — no move neededOne jump, one shot
马后炮 — the horse-cannon battery — is the palace's most famous firing squad: the horse lands on the king's file one square away from him, and the cannon sits behind the horse on the same file. The horse is the screen the cannon needs; the cannon is the check the horse cannot deliver alone. The jump looks quiet — no capture, no contact — and is mate, because the horse is untouchable from inside the palace and nothing can step between the battery.
