If villain is any good, I don't get why he is firing so large on the river. You're line looks like missed spades or air that gave up on the turn.
If he has a good hand, what does he expect you to call a psb on river with after your turn check?

I fire the turn here given flop raise, it's very hard for him to continue without an A.

I understand what you're saying about wanting to be deepstacked against the fish, but there's no guarantee that that big pot will come against you, and I wouldn't let it affect your decisions.

FWIW, if I'm making a play at this pot, I'm more inclined to float than bluff raise his cbet. Raising says I have a strong Q, spade draw, a 3 or air, as you're unlikely to turn a PP into a bluff here.
