In before everyone says x flop and that the sizing's poor.
I'm going to say it's an overplay. Your equity's not good vs a continuing range.

First for x flop. :P
Yeah it looks like solid spew all around, WTF is that 3bet, wtf is that turn shove.
Your line goes way over my head.

Without any reads on villain, I calculated his range as the following: 22, 55 - TT, A4d - AQd, KTd - KQd, QTd - QJd, JTd, 65d, and 76d. Against that range, we have 62.3% on the flop.

I honestly don't know whether the 4-bet is plus EV in this situation. I don't think we have much fold equity, we might be able to get a hand like 77 to fold, but I think all A high flush draws are continuing, and even the K high and Q high flush draws with two over cards might be continuing. I think maybe the right play would be to just call the flop 3-bet and see what happens on the turn. On the turn, I do not like the all-in. I would have probably checked the turn.

Why are we checking the flop with an over pair to the board?

Not sure why everyone hates this, surely often the hands that crush us on the flop don't just call the 3 bet given how wet it is. I would weight villain heavily toward a draw that isn't good enough combowise to get in on the flop, and given the turn totally misses so much of that range I feel we are good over 50% here.

Can also potentially get looked up by a pocket pair that thinks we are just shoving the scare card.

Yeah this is more or less what I was thinking, but still I feel like I jammed a bluffcatcher more or less (mostly to not give a free card to his draw heavy range) which somehow doesn't seem right. :P

If you have a 3bet range on this flop, what would be in it (assuming we don't x flop that is)? I mean there are obviously reasons to play this kind of hand fast (vulnerable overpair on a wet board), although I am probably mixing it with QQ. TT or JJ I would 3bet with even higher frequency. On the other hand I understand that CO should be very polarized 3way and not raise something like 88 (in practice I am not sure though, especially after him calling pre in the CO).

Yeah, but you're OOP and made the last raise on flop, he might check back the turn a lot.
