Villain is pretty loose and post flop pretty much a calling station, running 43/19/0.8 over about a 100 hands. His PF raises are minraises mostly though.
I'm running at 18/11 at this table.
Is this value bet on the river ok? The Q is a little scary but he did not show any strenght so far so I can't give him credit for that, right?
Comments very welcome...

what do you hope he will call with?

I guess he's hoping for calls by 34, A5, junk like that. This is about as razor thin as you can get IMO (i.e. I wouldn't) but you would know better than me. What else has he shown down?

I wouldn't be surprised if a Q9 kind of hand looks you up. There aren't really any tangible draws on the flop and with that AF its possible that he will not bet his Q on any street.

That's pretty exactly what I hope for, like every flush draw with third or fourth pair. We have to remember that he really is a calling station, that's exactly why I make this (I admit pretty thin) value bet here.
And he really showed down a lot of strange hands so far like As8s when board was 8 T Qs 2s K and he paid off KQ on the river...

Anyway would like to hear some more opinions, I'll post results later if there is interest...

Actually, I think he probably would have bet a Q or maybe even a pair of 5's or 7's on the river. I think that he plays JJ-88/66/33 this way about 50% of the time collectively.

I think you can bet it. You are going to get called by 22 and A-high often enough, imo.

There was no flush draw on the flop, so 43 is the only draw which could have paired. If he might calldown with some ridiculous A-high hand, I like it.

Villain is button, we don't know his river action yet.

Meh, sure we do...

meh, i guess bet. i would usually opt for a check/call but it doesn't seem like he will bluff us very often. It just sucks b/c even though I doubt he is folding a pair we beat, there are just so few hands he could have that we beat with which he could reasonably call.

If you really think he looks you up with A high then I like it.

I;d check it still
