iono about the flop bet, if hes a tough player this puts u in a really difficult spot. Also on this board many people arent folding hands like 88 or 99 when u just make a continuation bet, so i might slow down on the flop. Another thing to consider is that he called the 4 bet out of position, which makes me think that hes not calling light to try and outplay you. Based on the fact that he probably has a hand and you said he has a tendency to make light call downs. I would probably just fold the river as played.
