Conversely, if he goes on the hard pass and you defend the easy pass, he's going to lose one of those battalions.

相反,如果他选择崎岖之途,而你却防守平坦之路,那么他仅仅损失一个营的兵力

So his payoff, the attacker's payoff, is how many battalions does he get to bring into your country?

入侵者的收益,是他攻入你国家时还剩余多少兵力

He only has two to start with and for you, it's how many battalions of his get destroyed?

他只有两个营的兵力,而你的收益是入侵者损失多少兵力

So just to give an example, if he goes through the hard pass and you defend the hard pass, he loses one of those battalions going over the mountains and the other one because he meets you.

举个例子吧,如果入侵者与你在崎岖之途上狭路相逢,他在翻越山岭时损失一营,与你交战再损失一营

But if you were to defend the hard pass, if you were to defend the mountains, then if he chooses the easy pass, he gets both battalions in and if he chooses the hard pass, he gets no battalions in. So in this case, easy is better.

但是如果你选择防守崎岖之途,即你要低于高山巨岭,而他却选择的是平坦之途,他将兵力全存,而要是选崎岖之途,他将全军覆没,这样来看,选择平坦之途要好些
