Rob Wealth
Also called Jié Cái, the Wealth Rival
A chart describes tendencies in a traditional system. It cannot decide health, money, law, marriage or children.
In the classical sources
财者，人之所欲，方令弟兄见之，多有争竞
Wealth is what people desire. Let brothers catch sight of it and there is much contending.
淵海子平
About this relation
A stem that shares the day master's element in the other polarity takes this place: for 乙, yin wood, that is 甲. 淵海子平 explains the robbery through that same case. 戊 and 己 are the wealth stems of 乙, and 甲 takes 己 away in combination and breaks 戊 by control. The name describes what one stem does to another stem's holdings.
Names are tangled here. The 淵海子平 chapter says a yang stem seeing a yin one is 敗財 and the reverse is 劫財, 神峰通考 assigns the two names the opposite way round, and the table in 淵海子平 itself calls 甲 seeing 乙 both at once. 三命通會 卷六 treats 甲 seeing 乙 as one kind of 阳刃, the blade, a further name with rules of its own. This site uses 劫財 for both directions, which follows neither chapter's split and matches the 淵海子平 table.
淵海子平 tells the story as elder and younger brothers: the younger can ruin the elder's money and take his wife, while the elder can take the younger's money and dares not touch the wife. 神峰通考 says the elder seeing the younger does not overcome the wife at all, one more place where the two part ways. Modern popular writing softens the whole thing into competition and shared resources, and that layer has no passage behind it here.
