Villain is 21/15 and needs to be barreled off of hands. They're overly aggressive 40% aggression on flop and turn. They bet frequently when checked to

I raised intending to fire a second barrel on any dry board.

I went for the second check raise because
(1) the villain bets so much, and
(2) the board is so dynamic,

I think villain doesn't block me and most likely holds something like AJ or two high diamonds, which they can fold because my hand still looks like a monster. The downside to this I guess is a hand like pocket queens or pocket tens also has a straight draw.
