Hi there, been playing zoom abit right nw and got this this weird spot by the river vs a bad plyyer. Basically villian has been pretty loose and playing pretty aggressive. Saw him did some goofy moves where he has marginal and puts bets in without knowing he is bluffing or value betting. Certainly not a strong player.

Could check or bet the flop but with a bad player in the pot i'm more inclined to lead with is not all interesting. 

Turn seems like i'm obliged to call even though i think my range is somehow capped here a fairbit. Hopefully could go cc river.

River is kind of gross as i have 3:1 vs a guy that misplays his range a fair bit. Having the Aclubs blocks the nfd he is semi bluffing with and the 6 makes the str8 draw. But i;m having such good odds on this call that it's so tempting to just snap it off and move on with life. Having that said,i still couldn find hands to bluff enough here. Am i being exploited here by betting the flop vs a polarized range where the river my capped range is being attacked here? How often should we call or fold here gto wise?
