I play it the same. It's tough to decifer the turn check because it doesn't make any sense, but it does decrease the likelihood he's on a bluff. If he was bluffing on the flop, he'd bet this turn almost always because he'd be in a bluffing mentality and thus wouldn't be scared of any turn cards or of getting raised on the turn. If he was semibluffing the flop with J8/87/8dxd, I guess the turn check would make some sense since he now wants to get to showdown, but whatever the case is, I doubt you're good 1/6 on the river.

Also, the turn check is good--I can't think of any significant reason to bet it, and you subject yourself to a CR when you really wouldn't like to get CR'd.
