Wuzhang Plains
When Sima Fu wrote to Sima Yi to ask about the situation at the Wuzhang Plains, Sima Yi replied: "Zhuge Liang has big ambitions but he fails to recognise opportunities. He has his wits about him but is not decisive. He likes leading troops into battle even though he does not have much authority over them. Even though he has 100,000 troops under his command, he has already fallen into my trap and I'll certainly defeat him."
