Checking the turn seems like a good move to max value from a jack (even though it probably has a club kicker) and to exercise some pot control. And no I'm not just saying that because we happen to be talking about this hand where hero has a jack and a club. Villain might think that we could just put him on the Ac and call with our jack on the river, which might be true if we had another kicker.
