Does anybody literally play this way (utilize game theory to put your opponent on a hand, and then rapidly calculate your global probability of winning the hand based on the range of a hand he could be playing).

I supposed one example would be a loose aggressive opponent. The range of hands you put him on is everything, and you assume that you're ahead every time you connect with the flop in a somewhat meaningful way.

I don't think about my opponents' hands, rather my opponent's hand. After reading this article, I'm thinking about reconceptualizing the way I play through heads-up pots. (Instead of just getting an implicit feel for whether I'm behind, I'm going to consciously calculate the hand outcome based on my opponent's hand range.)
