pretty much a fish 39/11 over a couple hundred hands. He's spewy on the first two streets either donking or Cbetting but shuts down unless he hits by the river.

I'm not sure about betting this turn once he's called the flop. If he has 2 pair or pair and GS I want value, if he has KQ it's going in either way and I could use the extra card and not get raised before seeing the river. What should I be thinking here? Get it in before the scare card? Don't wait till he shuts down?
