It is complicated, more in my opinion yes, more always good to be careful, as will depend on the style of play of your opponent if he is a maniac, would be likely that the bet he could give rise and you end up thinking he has game and lose everything, however it seems that your opponent well and safe and conservative, if he is conservative will fold
first error comes up very little since first position and considering it is a free must be much more aggressive then I never attacked simepre weak juice even raise on the river that's a bad way to play a hand but I understand I scared the aces
I would bet 30-40% of pot on flop, to make sure he dont had Ace, if he re-raise i gonna call. turn i would bet again with 20 % of pot to make sure again to opponent if i'm not bluffing.
But if he shove on turn. I would like to fold.
