What would be perfect line?

preflop and flop seems fine, but I'm not sure about turn, if I wanted to bluf, I'd bet 12bb ott and overbet most river, if I think his range is still wide enough ott and I really want him to fold. x/r dosent seem to accomplish much imho, borderline spewy, we'll mostly get looked up by AJ or sthing.

Flop it is important to cbet big on draw heavy board, that way you can discard almost all Tx, Jx, Qx, Kx, Ax hands that could float vs your bet size (still unlikely 3way). That way it is good to cap opponents range, he will be left with some rare nut combos and weak PP which you can fold on turn or river. I dont like your turn play. Ax improves your range a lot and makes his much weaker, so you should bet. You will have a lot of FE already on turn. I wouldnt bet river If I would get called, because I expect reg to fold all PP 3way on turn. On this turn it would be ok to bet 50% pot, even 33% would be enough to fold his PP. If you would have Ax hand, and both you and villian know that A on turn is very good for your range and bad for his, then you would likely bet small with Ax, wouldnt cr turn, because you expect villian to check back very often on so ugly card?
