50NL AK top two 200bb deep. Backdoor flush hits.

[StubbornRussian]

Villain is 40/15/2.8 over a hundred hands. I haven't been at the table long and have no read on him whatsoever. He saw me get my stack by valuebetting aces pretty strongly over three streets.

What is my river plan?

I think he reraises two pair on the turn almost all of the time. So I put him on some type of pair of kings mid kicker hand, maybe Kxs, Txs, or Axd or a poorly played diamond draw of some sort. With his range, the majority of hands that will call a river value bet that I beat won't call a very large one. But I have no reads on this guy and I dont think I want to induce a shove this deep. But I dont think I see a shove too often without the flush here so what kind of value bet should I be putting out here and how do I respond to a reraise.
