孙膑Sun Bin

Sun Bin was a descendant of Sun Wu, the man who wrote The Art of War. He studied strategy beside Pang Juan — and Pang Juan, once he held a command in Wei, had his old classmate's kneecaps cut out rather than let him be used by anyone else.孙膑是孙武的后人。他和庞涓一起学兵法；庞涓当上魏国将军后，怕他被别国所用，先下手砍掉了他的膝盖骨。

He got out of Wei in a cart, hidden by an envoy of Qi. In Qi he won the trust of the general Tian Ji with a horse race that looked like a certain loss: send the worst horse against their best, then win the other two. Three races, three wins, nothing bought.他坐在车里、藏在齐国使者的车中逃出魏国。到齐国后，靠一场赛马赢得将军田忌的信任：下等马对他们的上等马，剩下两场全赢，一分钱没花。

In 354 BC Wei's army had Handan surrounded. Sun Bin did not march on Handan. He struck at Wei's own capital instead, and Pang Juan had to turn his army around — the siege lifted itself. Twelve years later at Maling, Sun Bin had his men count the campfires down from a hundred thousand to thirty thousand a night. Pang Juan, sure that Qi's soldiers were deserting, raced ahead with the fast troops and rode into the ambush.公元前 354 年，魏军围住邯郸。孙膑不去邯郸，直扑魏国都城，庞涓只能回头——围自然就解了。十二年后马陵，孙膑让人一夜夜把灶减少：十万、五万、三万。庞涓以为齐军逃了大半，带轻兵急追，一头撞进埋伏。
