NL5SH Zoom - AKs 4b pot

Villain is pretty much an unknown but seems to have somewhat reasonable stats based on the limited number of hands that I have on him.

Preflop: I didn't really feel like 5b'ing since villain was an unknown, we are both deep and I have position. Should I just get it in here since I don't know how often villain 4b bluffs me here? Should I just assume he goes broke with QQ+ and AK+? (against which I am slightly behind and I don't expect him to fold often)

OTF: It's pretty ridiculous because I assumed villains range to be QQ+, AKo+ in which case I am chopping at best which seems ludicrous. Decided to call at least since maybe he has JJ and AQ here sometimes and I obv chop AK, plus I have backdoors.

OTT: When I get 3:1 with the NFD I don't think I can fold although I can discount some outs maybe in case a heart pairs the board which may give me some reverse implied odds. Don't see any reason to raise.

OTR: Don't see any worse hands calling a bet given my assumptions about villain range, plus his line has been very strong so figured I have to check back here.
