hi
this isnt a good board for him to cbet so its like for him to have something . if you check raising here you are reping a set some two pair like 56 a flush draw or a slowplayed overpair . i think when the j of

comes you have to fire again if you take this line . other wise doesnt makes much sense
since he is so loose and likely to call a check raise with lots of hands on that board its not bad to check/fold actualy if you dont feel confident with it
as played certainly check behind river . their arent hands to get value from
