I don't think highly of villain over the small sample that I collected on him.. I've noticed that although there's a big discrepancy between his VPIP and PFR he still manages to 3bet about 5% of hands over this sample which I don't usually see with 30/8 players.. What do you make of my line? Is it any good? should I fold, call or raise river iyo? Fold PF? Fold flop? bet turn, fold to a raise? bet turn bet river?

I would sometimes fold preflop and sometimes raise the flop depending on the player, so I don't think there's much point in discussing that.

Not betting the turn here is really bad, he may very well call two streets with QQ/KK as is the tendency of donks and you're not really hiding the strength of your hand by checking the turn (looks like pair which plans on calling any river bet). You also lose value if something like a rivers or get drawn out yourself.

*EDITED: Flatting flop = checking the turn
