Don’t wanna tango with you, I’d rather tangle with him.

depsite all your preflop (over)thinking, it's close between a call, a raise, and even a fold preflop.

as for the flop/turn: you misplay to the tune of one small bet. when you have a fish out of position willing to 3 bet that flop once it gets heads up you need to almost always wait for the turn with your set. you will raise him then and he will call you down so you gain a easy, but significant small bet. key to all of this is the fact that bb is a fish. so he will misplay his hand and not make a laydown.

one more thing: fish tend to scare a bit easier (but again not to the point of laydown) when you pound with flop bets so it wouldnt surprise me if fish would never 5 bet the flop here with his most likely hand (one pair good kicker) and even with some stronger hands that he should 5 bet with like two pair.
