Protecting Post Categories when not signed in

I have successfully gotten Membership 2 Pro to protect posts based on the category by creating a protection rule that says these members get to see these posts. I cannot figure out how to say which posts people who are not logged in get to see. Can anyone help? I'm using the Recent Posts plugin in a widget. What I want is for everyone to see some posts, and then as members log in I want to feed them extra posts as well as allow them to see the posts everyone gets to see. Thanks!
