How much do you have behind after your $450 turn bet? This a hard spot and IMO is very player read dependent. Is he a guy that would stick in a raise here with the nuts or more apt to flat and go for river value? And to that point- what are the chances of him having 89 here?

Other than that we are scared of JJ,1010, and 77. All seem reasonable since you've seen him flat AA before. He flats flop here, and goes for protection/value on turn. Makes sense. But would he make this same play with QQ-AA? Here's where the player dependent reads (live reads too) might sway my decision.

Did you have the 10h?

expliotative read: live players like this will usually raise the flop bet of 210 as it is same as pre flop and on this board and with these stacks, tit looks weak. id expect a live players to usually have in their mind also a big hand would be increasing bet size from pre flop to flop always if they are strong. for that reason, i think he would be raising with his big hands to protect and want to get more money in the pot right then. so on 6 turn, nothing has changed. i think he actually might be turning a pair into a bluff here

With TJ we block top and mid pair, and we block mid pair fd. feels like this is a spot to go for x/r on turn depending on his sizing (if he has exploitative turn bet sizings) or x/c down, or if turn goes x/x value size the river from big-bomb depending on his tendencies to give credit to b/x/b line. I think when we check turn a lot of good things can happen, a ten that was folding can make trips, he bluffs his draws, he vbets worse. it is also a board that we are often one and done with aq or ak on flop with bkdr fd and brick the turn so checking our jt protects our checking range on turn.

as played it is tough spot but i would start with a call and decide on rivers, most likely fold given if rivers brick he would expect you to think he has many bluffs with all draws missed. we also beat aj-AA raising for sd, thought i doubt aj raises turn.
