Confusing hand

[Ojingo]

$200PLO on UB. Villain is decent, tricky and not afraid to gamble. We've played before, and I think he views me as a decent TAG. I've never got out of line against him, as far as I can remember. We both have a bit more than a full stack in the hand.

I get [9c][7h][6h] and limp in MP. There are a few more limpers.
Flop: [8c][4c], giving me the nut flush draw and a straight draw, as well as top pair. Checked to me, I pot. One opponent in LP calls, and villain calls in EP.

Turn: (3 players, pot=$56) . Check, I pot?!, LP folds, villain thinks a bit and calls.

River: (2 players, pot=$168) . Villain moves in for $150.

What do you put him on? What does he put me on? Is this a call?

Checking the turn would be a good line, which I'll take most of the time here. However, I thought that a pot bet would get at least one of them out, maybe clean up some straight outs. Also, I had been playing tight for a while, so I thought there was a decent chance to pick up the pot there, since quite a few players in the game would call lightly on the flop but give up on the turn unimproved.

Problem is this: if EP has 98 or a lower set then he should check if he thinks I have a busted draw, in order to let me stab at it again. If he has a lower set, then he should probably check or bet small, since now it's a WA/WB situation. Same for if he had something like 9TJQ, when his hand has some showdown value. However, if he puts me on a made hand (not unlikely, given the turn betting), he should probably lead with 98.

If he has a busted draw himself then it seems logical that he'd stab the river, but the confusing thing is that the 9 seems far from a good scarecard, since it is extremely likely to have helped my hand. I would have to have a very good read on my opponent before I bluff into that board, because I don't think it works often enough.

The scenario that worried me was where he had a hand like 89TJ or 6789 and where he puts me on a set. On the turn he still thinks he's drawing, but on the river he realizes that it was impossible I had top set.
