Given your reads, I play Third like you. Against a more seasoned, difficult crew (and maybe against unknowns) I would fold because there are straight and pair cards out along with another Ace.

I raise Fourth because the LAGboob will call with a gutter, fd or small pair, and the Aces will call and may even re-raise (which you ought to call). Getting stuck in the middle with a live flush draw isn't the disaster it is with a hand like one pair.

I would consider any non-diamond big card on Fourth street a brick, and would be unwilling to get put in the middle. If your hand was live in aspects other than Diamonds, I would probably see the Fifth card.
