Guy is very tight preflop but pretty aggro postflop. What's the plan for this hand? Since it's unsuited it seemed like a standard call PF? Does anybody 3bet preflop 200bb deep vs a nit?

Tight comes in different forms. Some people start with a tight range and fold a ton of it to 3bets, some start with the same tight range and overplay the weaker parts of it vs aggression. I think its not bad to have some 3bet/folds in your range against a nittier players btn opening range if you think they will only repot with AAxx.

On this flop, deep and with this sizing I don't like having any check raises. You will have to continue a lot here to avoid getting pushed around and he has a clear range advantage. I would use this hand to protect your calling range and play turns, especially against an aggressive postflop player.

Seems like a good spot to call with blockers? My question is do we expect him to continue with his bluffing range on the river or do we go for a c/c, c/f line?

OTT your hand is pretty clearly too good to fold. Its not doing well at all against his value range but you won't have better hands enough of the time to be folding here. There are lost of different lines you can take in this spot.

C/c with the intention to call down unimproved. This can be good against players who bluff a lot but won't value bet very thinly.
CC with the intention of folding brick rivers,
Lead looks weird but if you are leading with straights sometimes then the AT can be viewed as additional equity for your blocker bluff.
C/r has some merit as you block both straights and sets that might reasonably go b/c.

However you play this hand on the turn I just think you have to make sure that your range is uncapped, whatever line you take with it should be a line you also take reasonably often with KJxx.

OTF call is std, raising 200bb deep oop, will only get you call by wraps, ATxx, and sets with still a smalish stpr, keep in mind that any 6,8,9,J,Q,K. Will change the board dynamic so its better to keep it small OOP.

OTT seems like an easy ch/R imo, specially vs a tight player, ill make it around $20(folding to a shove) and something like 80% pretty much any river but a 7,J,Q.

idk how id play the hand a as turn call otr, i think x/R >, x/F, x/C

The thing is by barreling 3 streets in this runout he is repping pretty much AAxx, KJxx and well that's a pretty small range.....
The only hand i could see him bet 3 streets is something like JJxx, with something to go along for him to be betting the flop
