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

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

It is the case -- to introduce some jargon -- it is the case that the easy pass for the attacker, weakly dominates the hard pass for the attacker.

对入侵者来说,我们再词引入术语,对入侵者而言,平坦之途,弱优于崎岖之途

I haven't given you-- I've given you roughly the choices, the choice they're going to be for the attacker which pass to choose, and for the defender which pass to defend.

我还没有说完,我给出了大致的选择,入侵者选择从哪个途径入侵,而防卫者选择在哪里设防

In fact, we could check that if the attacker attacks through the easy pass, not surprisingly, you do better if you defend the easy pass than the hard pass: 1 versus 0.

我们来分析一下,如果入侵者选择平坦之途,毫无疑问,如果你选平坦之途要比崎岖之途更好,1比0

This is going to be the attacker, this is Hannibal, and this is going to be the defender, and I've forgotten which general was defending and someone's about to tell me that.

这个是入侵者,即汉尼拔将军,这个是防守者,我忘了哪位将军是防守者,最好有人来告诉我

You just want to match with the attacker.

你只是想刚好截击到入侵者

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
