[private joker]

I'd fold the turn. If MP1 hadn't called, I'd consider raising or just calling. But with MP1 calling, I don't like overcalling the turn with 6 dirty outs (you can't feel great about A[img]/images/graemlins/spade.gif[/img] or J[img]/images/graemlins/spade.gif[/img] hitting the river; and if someone has a K, your J outs are dead anyway). Just fold and move on to the next hand.
