i can't think of many hands he can have here that you are beating. 8c9c? maybe? so being out of position with a hand that is probably behind, i'm not sure you can do much better than 0 ev (check and fold).

obviously, any hand with a J is going nowhere. just for fun though, list of possible hands he could have that you might be able to fold:

AA, KK
9T
7x
88

7s is a little unlikely because of the flop action, unless it is 78. KK, and AA reraise preflop? 78, 88, AA, KK 3-bet the flop? do we know?

in order to be successful, villain has to have a hand he will fold enough times compared to when he's got a J. and then we've got to bet enough to actually make those hands fold, which means losing more those times he does have a J. someone can calculate, but it doesn't seem close to me. unless i am missing something obvious. i guess in the unlikely event that you are ahead, checking is a disaster...
