opp cc range is 11 from BU, 3b is 4,5, fold to 3b% 0... i have 720 hands on him

Standard play pre

OTF i thought opp range is capped to PPs so a bet should fold most of them and plan to go for 3 barrel here.

OTT i think here is sizing mistake. if i want to jam river i should have bet bigger

OTR very good card to jam since opp should not have FDS that X/C twice and i would have heard before of sets (2 combos ). but i am not super happy since turn brought other draw and i have Kd myslef

anyways, this is my doubt. otr my 3 barreling range for value in this spot looks like this:

QQ+,AcKc,AcQc,AcJc

now this is my doubt, how many bluffs can i have otr? assuming opp bluff catching range is basically this QQ-88 maybe 77 and perhaps some 9x too if he decide to call IP.

i really dont know how to create a bluff range in this spot, and when i played this hands i thought Ackd could work, also is it necessary to have one against reg such as this opp? I think i need to know opp folding frequency on the river and whats fold equity there, but im beginner with that and if someone could help me i would be really thankfull
thx
