on the flop especially at pstars im worried about ten jack, the turn I dont mind being agressive as I got the board pairing as outs, not to mention he has to consider you made a boat if he has something decent.

The fact that he knows you leads me to believe to keep this pot small as he might want you to bet those kings with ten jack, or a made boat. On poker stars I am assuming you got set up some how..Question what did he have?
