How do pre- IV gen special and physical moves work?

Question

ex: a special move blaze kick hits a specially defensive gardevoir, but it physically hits it... what happens?

Answer 1

Since all Fire type attacks prior to Gen IV are Special, Blaze Kick would hit based on your Special Attack and Gardevoir's Special Defense.
