I made the oblique CAMESTRES syllogism:
Dick is a smart man.
Joe is not the son of a smart man.
Therefore, Joe is not the son of Dick.

I reduced it to first figure CELARENT and came out with:
A smart man is not the father of Joe.
Dick is a smart man.
Therefore, Dick is not the father of Joe.

Is it no longer oblique because the middle term no longer has anything to do with the transitive relationship? Did I goof up?

CAMESTRES
(A) Dick is a smart man
(E) Joe is not the son of a smart man
(E) Joe is not the son of Dick

Reduces to a CELARENT like this:

(E) No smart man is a son of Joe
(A) Dick is a smart man
(E) Dick is not the son of Joe
