What makes you think that "2-3 openings and/or defenses" is "theory of chess"? I'd rather call that "theory of openings".

My advice is to grab a classic book of a great player from the pre-computers era, and study it on your own, or together with your son - there's at least a dozen of such widely acknowledged chess books. Feel free to ask for suggestions.
