I 3bet the turn everytime because he usually has Tx or like 55/ 88 etc. After your turn play, your river play is probably optimal against a predictable opponent who will check through with hands I listed in sentence 1 but not bluffraise a bet.

Your only read was that he is "generally aggressive." In my mind this means I cannot trust him enough to bet fold. A bluff with a busted spade draw or random KJ hands are possible.

The big problem is not 3betting the turn imo.
