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

But if the attacker was to attack through the hard pass, again not surprisingly, you do better if you defend the hard pass than the easy pass.

但如果入侵者选择崎岖之途,仍然是毫无疑问,选择防御崎岖之途要比平坦之途好

And how many of you think you're going to defend the hard pass?

那么有多少人选择防守崎岖之途

Well if you're not defending the easy pass, he doesn't lose anyone, and if he attacks through the hard pass he's going to lose at least one battalion.

如果你没有在平坦之途设防他兵力不减,然而如果他从崎岖之途进军,那么他将至少损失一个营

Now since we think that Hannibal, the attacker, is not going to play a weakly dominated strategy, we think Hannibal is not going to choose the hard pass.

好了,既然我们认为入侵者汉尼拔,不会选择弱劣势策略,我们认为汉尼拔不会选择崎岖之途

And how many think you're going to defend the hard pass?

有多少人选择防守崎岖之途

It's not the case that for Hannibal, choosing the easy pass to attack through, strictly dominates choosing the hard pass, but it is the case that there's a weak notion of domination here.

对汉尼拔而言,选择平坦之途入侵并不是,严格优于选择崎岖之途的,但是在这种情况下有一个弱优势

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
