We have to be a little bit careful.

我们要更严谨一些
It's not the case that for Hannibal,

对汉尼拔而言
choosing the easy pass to attack through,

选择平坦之途入侵并不是
strictly dominates choosing the hard pass,

严格优于选择崎岖之途的
but it is the case that there's a weak notion of domination here.

但是在这种情况下有一个弱优势
It is the case -- to introduce some jargon --

对入侵者来说我们再词引入术语
it is the case that the easy pass for the attacker,

对入侵者而言平坦之途
weakly dominates the hard pass for the attacker.

弱优于崎岖之途
What do I mean by weakly dominate?

我所说的弱优于是什么意思
It means by choosing the easy pass,

它意味着选择平坦之途
he does at least as well, and sometimes better,

较选择崎岖之途而言
than he would have done had he chosen the hard pass.

至少要同样的好可能还稍微好些
