id be more interested in how our opponent reatcs with a mediocre/lukewarm hand to a second barell on a blank looking board. Id also want to know how they will play a flush/oesd draw to determine how much id c-bet against them
Thats on top of a range of hands i expect my opponent to have and their likelyhood to have hit any given flop of course.

eg if someone is calling my pfr's a lot with AJs/ATs type hands (dominated overs) then im much more likely to c-bet hard into rag flops than i am into a bunch of broadway's when i miss. If somone is calling with a small rnage that is basically only pps then im much more likely to take my free card, but ill c-bet/2 barell into these guys enough to force them to fold mid pps more often than they should versus my range and declare they have a set early on a smaller money street.
