200NL; flopped flush OOP in raised pot

[Halv]

Villain is 19.5/1.41/passive postflop over ~50 hands. No read.
Hero has been aggressive but has not been caught making too many moves.

On the turn I wanted to induce a raise from an overpair/set of jacks, or at least keep him in the hand. Looking back at it, given his passivity, I should have bet more here in case he has a set or a high diamond and also to make it easier to get all in on the river, right?

What's my move on the river?

Against an opponent with more aggressive stats, I like a push, but here I like a smallish, callable bet... $50 seems about right.

bet $100, he isnt folding.

[Halv]

he isnt folding.

That's what I figured too, so I went for the full pot sized bet. He then raised me all in for ~45$ more. Suspecting he had the one hand in his range that beat me I still had to call given the huge huge potodds, right?

Of course he flipped AKd for the nuts.

yeah too many sets or overpairs that will call.
