所以她会选择α
And once I know that she's going to choose Alpha,

一旦我意识到她会选α的时候
it's clear that I should choose Alpha and get 0

很显然我应该也选α来得到0单位效用
rather than Beta and get -3. So I should choose Alpha also.

而不是选β只得到-3 所以我也选α

the evil git versus the indignant angel;

饭桶恶魔博弈愤怒天使
and the indignant angel against the evil git.

和愤怒天使博弈饭桶恶魔
