dummy end of straight against loose donkbettor

[***]

My pokertracker wasn't working while this hand was played, so I haven't noticed much about villain. I'd say he's at least somewhat loose and doesn't seem sharp. I'll extend that generalization to postflop play, although I don't know anything in particular.

What's the best river action? If I raise, what raise size is best? I am especially interested in the sizing here as much as whether to raise or call.

I would either just call or min raise/fold

Yeah.

If we raise I think only a really small raise (minraise) or to like $125 might get two pair/set to look us up.

Anything else and we are only getting called/pushed on by better straights.
