Knowing the basics of GTO, and improving on frequesnt occurance simple spots is always a good thing.
However, when I see people saying stuff like, and they raised with garbage and I got drawn out on, or they called my great
bluff, when I was telling a story and representing a certain hand, you knowing they were playing players who don't look for that stuff.
There's no point representing a flush if your opponent can't fold top pair. Or running any bluff on them at all for that matter!!
Not that I really play mid stakes, but certainly at low stakes you have to focus on playing the players, and mostly assuming that GTO will not be the mst effective method of playing poker.
