Final Pot: 13.00 BB

BB is fish that likes to bet any pair he makes on the flop with 1-2 players in the pot.

I'm figuring the turn I'm good with top 2 pair vs this guy and then he 4 bets me. On the river would it be wise to call or keep raising assuming he has 2 pair? He are HU?

Is the betting thats the problem? When I am ahead I win 1 exta, when behing lose 2 extra?
