Villain is unknown <10 hands, but 1/2 stacked and his flat certainly argue that he's most likely bad. Fairly stnd open I think, seems like a decent board to c-bet, and just shutdown to anything but a fold obviously, but the question is, what is villains b/c range on the river? More than that, what's villains PSB/c range?I mean obviously all his nut hands, but does he call enough w/ random shit and A's to make this profitable? The flop call was c/insta-call.
