They are smoothed (besides the rook. I had major problems with that one so I revolved it to it's current level of detail and worked on from there) , though for the knight I had to make some finishing touches after smoothing, and I don't have the unsmoothed versions (besides the knight).
Can you post a pic about the advice for the knight? I don't know how to make those quads besides deleting some edges but that doesn't help much.
