Villain is kinda crazy, he plays 36/29/23.3 with a fold to 3bet of 0 and 4bet range of 4/5, WTS% 33% over 402 hands

Preflop i have some doubts, vs regulars and some fish i 4bet this hand CO vs BTN, vs this guy do you agree with this? I think that he plays so wide that a hand like this which migh be a pure bluff vs a lot of player at 10NL ZOOM will be a good semibluff vs this guy and with good implied odds if we hit.
Also my sizing was not the default one, i must have miss clicked since i usually 4bet to 2.2x

On the flop i decided not to cbet because even a guy like this that may call 4bets with a overly wide range, will have hit that flop in some way more often than not, he migh have JJ,KQs,AJ+ who knows.
But do you think it will be more profitable to b/gii on the flop?

On the turn i think i'm staking off if he bets, we only need 30% equity if he shoves, so even putting him on range of AxQy+,AJs+ and JJ-QQ, and i think that he has a wider range than this we have 39% equity. Do you agree?

OTR i tough briefly about shoving, but i don't think we are gonna make this guy fold a A ever, so i decided to just x taking our SDV beating something like QQ or TT that this guy might have, probably folding to a shove. What do you guys think of this line?
Vs a good regular i would've probably bluffed representing QTs which is on my 4bet bluffing range CO vs BTN, and the diamond flush since i could also 4bet things like Ad2d-Ad5d, that call the flop and x the turn.
