I would generally check the river. You lose a lot less if you are beat, and sometimes he bluffs or even value bets a weaker hand. It is certainly easier to play if you check. Villain probably doesn't check the flop with a flush draw, so betting and calling a raise might be good.

In pot limit, I like leading into the raiser OOP on the flop. If he bets, then checkraising or check/calling both have problems, and you don't like it when he checks behind.
