Agree that we need af stats as well as agr stats on each street as they could change my viewing of the hand and vils range considerably. But with the current description of the villain i dont agree he bets this river with kj, k10, he wud more likely check behind river. Hed also never bet this river with top pair weak kick and would check it down. I also dont get why you are disregarding 44 or 88 in this spot as hed play them the same. Yes its possible he has 45 spades, 67 spades etc but his range is weighted far more to hands we lose to.
