I am not far from being a noob – so take this with a grain a salt.

Would you try it with tags ?

One home page but only include posts with certain tags for each situation

For your landing page (for non logged users – tag -red) So its only a “landing page” for non-logged in users.

function xonlyinclude_tag($query) {
if ( $query->is_home() && !is_user_logged_in()) {
$query-> set('tag_slug__in',array('red'));
}
return $query;
}
add_filter('pre_get_posts','xonlyinclude_tag');

For your logged in ordinary users (tag – green – normal posts)

function onlyinclude_tag($query) {
if ( $query->is_home() && is_user_logged_in()) {
$query-> set('tag_slug__in',array('green'));
}
return $query;
}
add_filter('pre_get_posts','onlyinclude_tag');

put the 2 functions in your functions.php file

just a thought.
