ripping turn as a bluff 3bet pot

I wouldn't have many problems of getting it in vs CO. However, as played, I would x/r OTF already and stab again OTT. You have more FE vs villain based on the turn card. You can stab again here and villain here would mostly fold. Don't forget, we are mostly behind in absolute hand strength and thus we need to put pressure on villain.

Against a reg or a non-nit this is an easy 4bet-stackoff pre.

It is played fine. However, you need him to be able to fold an overpair on occasion. Otherwise you have just a call on turn.

Getting it in pre is okay too. (But check-raising on the flop already is just blind costly aggression. You have no credible draw. (Runner-runner backdoors usually count as only one out apiece.))

I agree with not 4B/calling off pre.
I like how you played it, but I'm not too sure about the huge check-ship, although we don't have much room for much else. I think it looks a little bluffy.

AK is the single hand that makes mathematical sense to move in with preflop ''as aggressor'' a disproportionate amount of times, especially OOP. Essentially, the only downside is that a clever opponent may put you on that hand and (correctly) call with 22+. This takes unusual guts, so you can profitably 4-bet all in here. Whether the other options (normal 4-bet and call) is up to you. The latter plays require more postflop skill obviously.

From MP we can 4b and we can just call preflop.
On turn I prefer to call. Our draws are backdoor and we can get calls if we hit.
