Fishy slowplay?

I don't like a river cap the way you played it.

If button is loose passive, you probably need to raise the flop. If you raise the turn, the button might not pay.
Thats why they advise to wait to the turn to raise vulnerable high hands. You hand is much stronger than a typical vulnerable hand. If the button pays the flop, the button is more likely to pay the turn as well.
As a bonus, if BB has a big pair, you are likely to be 3-bet on the flop, but less likely to be 3-bet on the turn.
Also, sometimes a TAG BB will smooth call your flop raise and check-raise you on safe turn, which is great for your hand.
If you don't raise the nuts as a matter of course, you will find your flop raises less respected, and since you should be raising the flop a lot, this will hurt you.
