$100 PLO, 4 handed. Villain is decent 2+2 regular who respects my game but also knows that in SH games I'm very aggressive in position and will raise and CBet lightly.

Normally I wouldn't lose too much sleep over this one but I dropped a few buyins on another table to quite ugly beats (including one for double stacks where I had 7889 on a 568 board and villain called a 4bet allin on the flop with just a K-hi flush draw), so just verifying that this wasn't a tilty overplay on my behalf.

I have [Jc][9c][8d] otb and raise after a limper, all call.
Flop: [8s][3d]. Check, I pot, only BB villain calls.
Turn (pot = $57): . Check, I pot, villain CRAI for $20 more, I call.

Once he CRAI it seems clear that I need to improve, so a check behind may have been better given his actual holding. What's his range for CRAI here? Anyone advocate another line? In hindsight I thought that a smaller turn bet might have been better to keep weaker draws in. On the other hand, I do want to keep my action image and get him to make a bad call right?
