AA on paired board faces 3bet.

Firstly, please post your thought process.
Any reason to open 5bb?
I would consider checking back that flop sometimes. You don't need protection, only a diamond could bring trouble OTT.
Cbetting is ok, a smaller size should do the job.
Turn is a brick, so betting is fine. Although I wouldn't give you too much credit for bluffs on this board, only flushdraws.
I don't think you have 3 streets, so sizing up a little bit OTT with the intention of checking the river is a good option.
Turn check-raise is small. In position this is a clear call, you can't be calling only Jx here because it is exploitable.
River SPR is around 1.5.
Raising doesn't make much sense. He will show up with Jx more often than not, but against a 1/3 bet you have to call with AA tbh.

Seems like a solid table overall for NL2 except the CO player based on the stats.
Only reason for me to raise that much if you think the CO will call you with pretty much any hand if you raise.

Flop Cbet sizing isn't to crazy, but against a BB will pretty much only call with a decent pair or better hand if you bet 2/3 pot. Turn is tricky. It makes not to much sense for him to raise with less than trips and is folding not to crazy on NL2. Off course it could be exploitable, but on NL2 I don't see a problem with that against players that doesn't know this concept most of the time.

River seems like a milking bet and you beat only a bluff I think. I doubt most players will do this here on NL2.
