Bet call river. With his turn line he's obviously a fish, so he can be overvaluing many hands. He might (although he probably shouldn't) shove a lot of hands for value that you chop with too, such as 56, 67, 68. Considering your only read is that he has a tightish range OOP i think something like 67suited is more likely than a hand that beats us such as 6j (although he does have A6 quite a bit if he shoves). 99 and QQ probably 3bet pre, so it's unlikely he has a full house imo. I'd bet about 15 on the river fwiw. Also opening to 4xbb is too much.
