I think u should call his 3bet preflop because then he will normally bet flop and turn (hoping u fold turn, since for what he knows u can have a big range of hands) and he will call a raise and play back at you with a 3bet with a wider range since he is missreading your hand.

In this actual hand I would bet river and normally call but fold if he was passive/loved to slowplay big hands.
