I haven't been playing too long myself, but if it were me, I would lower my calling/raising standards against this particular person some, depending on my relative position to him, of course.

If I'm directly behind him, I'd probably call with hands that I would fold behind most other players. If I'm 5 seats over and someone else calls/raises, then I'd probably play a little more conservatively.

I don't think there's any -perfect- formula. The rules and standards the great players have must be modified from time to time to fit particular situations, I would think.
