I think his range is obviously wider now that CO is in the hand. BB must know that CO is a huge fish too. So because of this it's not that unreasonable for him to have KJ.

He's donking into 2 players OTF, one of which is a huge fish. He continues to donk the turn on a paired board deepstacked. The Q pairing hits both of your ranges hard (maybe favours his slightly).

KJs - 4 combos
KJo - 12 combos (or less depending on discount)
AQ - 8 combos
KQ - 8 (or less depending on discount)
QJs - 2 combos (depending if he donks this weak of a Q but it makes sense given the flop draw and positions)
99/TT/QQ - 3 combos

I mean I understand what you're trying to do with the blockers but when you examine how many value combos he still has that aren't folding I think we can just pitch the hand and wait for a better spot.

look at aussie millions 2014 cash game. doug polk makes play similar to this, but flats turn and jams river on 7545Q with 74 against patrick antinous (who ends up betting 90k and calling wcg's raise to 302k with 86 after a long tank) 

related to that, if you had TT 99 QTs Q9s, wouldn't you flat turn?

flop i think a raise is nice here; our hand is weak to 8/T/J, we loose a lot of equity & value on these cards; his preflop and elad flop let him on a narrow range of AQ,KK+ most times, so i raise the flop

turn, i don't like the raise, yes you have blockers, but Qx ,KK+ won't fold, so just fold

Calling flop is fine imo, and I would call turn and bomb the river. I don't think villain should give us as much credits for this line since we would pretty much never play a boat like this.

I think he could defend AQ,KQs,KJs,QJs but dont think he would flat AK,QQ,KK,AA because fishy CO and he could consider your range wide since you are stealing often from BN so he would probably reraise, i can see him flat pocket pairs like 66,77,88 trying to catch a set.

Now, calling his bet with two pairs on wet board like that is ok (he would bet KQ,AQ and maybe with 66,77,88 to try to force you off) but when Q hits the turn i think its time to fold your hand. I dont think he would just fire in you with air because that board connects with your range too and he knows it.

I have to raise flop here.

'Not sure he donk AQ, and he probably doesn't cold calls KJ pre.'

Still a very good line for him to donk AQ with the whale in the pot. As for PF, I think his range can be very very wide, and can def include KJ (at least KJs, for sure), considering there's the fish involved and you are 300+ bb deep. And you do iso 3b the fish with T9o, if the reg is good and realize how wide you are, he should cold call a lot from BB with effective stacks. This hand looks like a live cash game hand to me ; if vilain is indeed good deep (which is not the case for most online grinders), then you should expect him to play as if it was a deep live game.

I don't mind the flop peel, although raising would make a lot of sense as well. If you peel, you're not really trapping, it's more to disguise the strengh of your hand if the board runs out well for you. Turn looks very spewy to me. You look full of shit. If you really want to pull out the play and make him fold AQ / KJ, then raise bigger turn and shove river, but that's not even gonna work often enough if you have a spewy image. Are you even always 3betting 99 pre? Will he really expect you to flat the flop with a set?

much more credible to flat turn/raise river. its just that ur almost never good when raise turn so if he checks river, i guess you gotta over bet.
