i agree with surviva, but i still think you can 3b for value a lot more because hes still calling when behind, bloating the pot and making it easier to play for big pots in the situations you both described. You are deep, he is a fish. You have a bunch of notes on him that he basically takes top pair crap too far although one qualm i have is that you have a note that he c/c top pair weak kicker on flop, so obviously you got to see a showdown, how come you dont have what he did on the other streets written down, did it just get checked down the whole rest of the way?

and as for flatting i think you have it right, lots of suited connectors, maybe some of the better suited 1-gappers...obviously you know with these hands (especially like JTs, QTs) you are not trying to hit top pair. It sucks that most of your flatting range is a draw so i guess it couldnt hurt to strengthen your B range and include some AJ, KQ ect

oh yae and im a complete moron just so you know, my responses are mostly for me trying to figure this out, rather than being critical of what you said
