Stratagem No. 11 第十一计 Enemy-dealing stratagems (敌战计)
Sacrifice the plum for the peach
Literal
The plum withers in the peach’s place.
When you must lose something, spend the piece that costs least where they are strongest, and keep the better piece for the win.
Source line
势必有损，损阴以益阳。
Traditional 勢必有損，損陰以益陽。
When the situation forces a loss, damage the yin to benefit the yang.
Icons working translation — draft, pending review
Yin here is the lesser, expendable part. Yang is the part that must survive or win. The wording sits in the same family as the hexagram Sun (Decrease): you accept a real loss, and you choose which side of your own strength bears it. The text does not promise a way to lose nothing.

Meaning
Sacrifice the plum for the peach means giving up a lesser thing on purpose so that a greater thing survives. The loss is coming anyway. The skill is in assigning it. A commander who tries to save every unit loses the army. A negotiator who defends every clause loses the clause that mattered. The plum is not worthless. It is the piece whose loss you can bear, offered where the other side is strongest, so that your better piece meets them where they are not.
The image is a tree dying in another tree’s place, which is why the stratagem feels moral and tactical at once. The original poem is about a brother taking the blow. The manual turns that into an exchange of unlike pieces. Sun Bin’s horse race, the commentary’s illustration, is the cleanest form: you knowingly lose one heat with your worst horse against their best, and you win the contest. People who hear only the poem think the stratagem asks for noble self-destruction. It asks for a calculated one, and for a contest that is scored across more than one encounter.
The story
Sun Bin’s horses for Tian Ji 田忌赛马
History
Before the campaigns for which he is remembered, Sun Bin made his name in Qi with a horse race. Tian Ji, a noble of the Qi court, often wagered heavily against the king’s sons and, the story implies, often lost. Sun Bin watched the horses and judged that the animals in each stable were not very far apart, and that both sides classed them as upper, middle and lower. He told Tian Ji to raise the stake. He could make him win.
Tian Ji trusted him. The match was against the king and the princes, and the Shiji puts the wager at a thousand gold pieces. At the start Sun Bin gave the pairing. Tian Ji’s lower horses would run against the king’s upper horses. His upper horses would run against the king’s middle. His middle horses would run against the king’s lower. The first heat was a loss, and it was the loss they had chosen. The next two were wins.
One defeat and two victories took the stake. Nothing in the method required a better stable. It required a scoring rule that counted matches rather than a single race, and a willingness to present the worst piece to the other side’s best. The Shiji tells this as the episode that bound Tian Ji to Sun Bin, in the years before Guiling. It does not give a year. The neatness of three classes and three heats is the received account, and it has the shape of a lesson the historian was glad to keep.
Told in Sima Qian’s Shiji, chapter 65, as the episode that won Tian Ji’s confidence before the Guiling campaign; no year is given.

Myth check
The words come from a Han ballad about brothers, in which the plum tree dies so the peach can live, a plea that kin should not abandon each other. The stratagem manual turns that family image into a tactical trade. Sun Bin’s horse race is the manual’s illustration, not the poem’s.
Modern application
A sales team that must lose one account should decide which account, and lose it to the competitor’s best people, while its own best people are on the two accounts that can be won. A negotiation does the same with clauses: concede the term the other side has come determined to take, early and cleanly, and spend the goodwill on the term that changes the price. The error is to concede at random, or to concede the peach because the argument about it has become unpleasant.
Sport uses the pairing openly. A coach rests a star against an opponent’s star, accepts that loss, and plays the star into a weaker matchup that decides the tie. The method is useless in a single, unrepeatable trial. If there is only one race, sacrificing the plum is merely losing. The stratagem assumes a score that adds up across several contests. One isolated result cannot repay the chosen loss.
Takeaways
- Choose the loss you can bear before the contest forces one on you.
- Match your weakest piece against their strongest.
- Spend your strongest piece where it can actually win a counted result.
How to counter it
If an opponent concedes early and cheerfully, look at the scoring. They may be giving you the heat they had already decided to lose, in order to win the match.
Questions
What does sacrifice the plum for the peach mean?
It means accepting a real loss in a lesser piece so that a greater piece can win. The classical line says: when loss is certain, damage the yin to benefit the yang. The usual story is Sun Bin advising Tian Ji to lose one horse race on purpose, with his worst horses against the king’s best, and to win the other two. One loss and two wins took the stake.
Where does the plum and peach saying come from?
From a Han ballad, a poem about brothers, in which insects attack the peach tree’s roots and the plum withers in its place. The Thirty-Six Stratagems take the image over as a military and political trade: give up the expendable thing. The ballad is about loyalty inside a family. The stratagem is about how a contest is scored.
