No read on villain here. Should I call or reraise this C/R on the river?

I'd simply call. I don't want him to push back on me and agonize over the two possible hand that I'm losing to.

I like to bet the pot on flop, but that's just me. I don't think it's particularly right or wrong either way.

Let's see about the river. J9, 97 are all that beat us. The question is, what range will he call a raise with? I think he will call a raise with any straight, as well as any set. 55 is most likely, but its possible he slowplayed 66 or 88. TT or QQ pretty much never. Also, random twopair hands may call a river raise, like QT.

I think I just call, because when he calls our bet we are beat most often. I don't think there is value in raising, so just call.

i'd reraise... 79 seems unlikely since i'd imagine he'd bet the turn once the flopped checked through.

9J is possible, thats the only likely hand i can think of that beats you.

i'd say this is some rivered two pair most often.
