So the first argument, that's a straight forward argument, the second argument says, I put myself in other peoples shoes, I realize they're not going to play a dominated strategy, and therefore, having realized they're not going to play a dominated strategy, I shouldn't play a strategy between 45 and 67.

所以第一个过程是直截了当地,而第二个过程,我从别人的角度思考,发现他们并不会选择劣势策略,意识到他们并不会选择劣势策略后,我也不应该选择45至67的数
