3/6 Maximizing vs. TAG

[Harv72b]

CO is a multi-tabling TAG that I've played a lot against. Might be a 2+2'er, I'm not sure. He's 25/17 (edit from 12)/3.2 over a 3k+ sample. I also have some history with him in the FR games on Party. He is very capable of making tough folds at any point in a hand.

I think he knows that I would 3-bet his CO openraise relatively lightly, but regardless of that I view his cap as meaning either AK or AA-QQ. The fact that both of the blinds are loose/terrible probably gives my 3bet a little more weight, too. His bet/3-bet line on the turn (coupled with a noticeable pause before 3betting) tells me that he has an overpair pretty much 100% of the time here, and that it's going to be AA the vast majority of those. I believe he would have expected me to raise the flop with a ten, so he's very unlikely to put me on turned trips.

Given the read, go ahead and cap the turn, or call the 3bet intending to raise a non-ace river or bet the river if he checks to me?
