At the superposition of blessed and cursed

Case in point: Tsun Zu's rival defended a city with 10 men against Tsun's army of hundreds by disarming his own soldiers, dressing them in plain clothes, INVITING Tsun's army to come in, and it only worked because Tsun knew the guy was an ambush master and thought "if we attack the city he's inviting us into, we will die." and left without even trying ON THE BASIS OF HIS RIVAL'S REPUTATION AND NOTHING MORE

Another example: Tsun Zu, on being told his soliders were out of arrows during a battle against a city across a river from them, had his men craft scarecrows, put them on a boat, send it out on a line, leave it there for half an hour, then pull it back in and used the arrows the enemy had fired at the boat to restock their own ammunition. It only worked because it was foggy and the enemy couldn't tell the difference between the scarecrows and actual soldiers.

I've had this idea stuck in my head all day
