What are your plays against someone who consistently re-raise your preflop raises ?

lets say 6 max you are in CO with KJs and open raise 4 times the BB. Only the BB is still in the hand and makes it 8 or 14 times the BB, and you fold. After that fold he makes it everytime you open raise with a hand. What is your play during a session against him ?

I'm not always clear on terminology, but I assume that open raise means raising to bb+1 sb from a non-blind seat.

Well, you should basically be willing to open raise almost any hand you limp in with anyway, since it doesn't really make sense to put money into the pot unless you're getting the best of it.

So, technically, if he raises every time that you open raise (assuming he's behind you), it should already be more profitable if you just open raise and then call. There is the drawback that this increases the pot size, could lead to a disproportionate increase in variance, but this shouldn't be a problem if you're properly bankrolled. If variance is an issue, restrict your open raise range slightly.

Another option is to use an open raise - jam tactic to exploit the behavior. Since you know that he's going to re-raise, you can restrict your open raise range, and then re-reraise hard or push when you're heads-up with a premium hand. Notably, game theory research indicates that pre-flop jam/fold play in NLHE can be very close to the game theoretical optimum anyway. Of course, this has the drawback of discouraging this exploitable behavior.

Basically, these dogmatic reraises are clearly exploitable, since you're getting the other player to voluntarily stick money in while you're getting the best of it. Thus, you want him to continue doing it, so, I'd say the best route is probably the following:
Restrict your opening range, with the intention to call the reraise.

If these reraises are causing you big problems, then there's probably something wrong with your game, or you're playing outside of your bankroll.
