i think a good bit of his range here is a whiffed crai on the turn with 33, kq qt j9 .. and that riv bet screams value, i fold this to an unknown and dont really think to much about it, i think if you weight his hands that he bets on the river (ie not qt,at,t9 tj bc i dont think most ppl turn those hands into bluffs) it leaves you with a very small % of hands you beat, mainly axh or similar FD's, and his other holdings are far more likely imo
