View node public OR only to verified/role by choice user
Found a way to do this with tags. Feel free to add information about doing this with tags: 


Added a taxonomy 'visibility' with 2 tags: public and closed.
Added to Contenttype a field with a selection-list (so, a user can only choose one). 


(set it to requiered to only have 2 options.)
(in my case, i set the default to public.)

Enabled taxonomy-module 'Taxonomy Access Control' 
go to admin/config/people/taxonomy_access >> anonymous >> choose [edit access rule]


(in my case it's admin/config/people/taxonomy_access/role/1/edit)

Under New >> choose the term 'closed' (or your equivalent like 'not for mother-in-law ;-) ).
Set everything to D (Deny)
When Content Access is also on, set grant priority to -1 on the   contenttype-page (admin/structure/types/manage/[contenttype]/access
