      I think you misunderstand "folds under the cursor".

      With the cursor on the A node, folds on B and C nodes are not under
      the cursor at all. Therefore zC does not close them. Note the text
      of :he zC, which says, "Folds that don't contain the cursor line are

      But with your cursor on the C node, zC will close the B node above it
      and the A node above that.

      What you probably want is to adjust the fold level with zm/zr/zM/zR.
      You could also use :foldclose! with a range (where a range could be
      determined by a complicated regex or a visual selection even).

      I also just learned about zC in visual mode, from reading the help.
      Another solution would be to visually select all the lines which you
      wish to close all folds in, and use zC on the visual selection. With
      the % command and the matchit plugin, this should only be a few extra
      keystrokes (e.g. V%zC instead of just zC). This should do about the
      same thing as :foldclose! on a visual selection but with fewer
