Which concepts do you think is the most effective strategy in Sunzi’s Art of War?

During the Warring States Period, the world was dominated by small countries, while the big countries struggled for hegemony. In the ghost Valley of the Central Plains, there is a man who knows not only the nature and geography, but also the art of war, known as the Ghost Valley. Guiguzi had two proud disciples, one was Sun Bin, the second son of Sun Tzu (Sun Wu), and the other was Pang Juan. At the invitation of the State of Wei, Pang Juan went out before Sun Bin, and Guiguzi passed the lost "Sun Zi's Art of War" to Sun Bin alone. Pang Juan became the marshal of the State of Wei. Together with the king of Wei, Pang Juan led an army to attack the state of Chu. The troops of Chu could not hold each other in the city of Fang. Pang Juan sent his adviser Gongsun Yue to ask Guiguzi to give him a good idea. Guiguzi pushed the matter to Sun Bin. Sun Bin quoted Sun Tzu's Art of War and offered Gongsun Yue a plan to "get up the house and pull out the ladder". Pang Juan used Sun Bin's strategy to lure the Chu army inside the city to attack, then cut off the back road and destroyed the Chu army. The state of Chu was forced to cut the city to admit defeat.
