Parham is an Indiana master/expert with some very interesting, if not
wholly correct, ideas. I believe he uses vector analysis in his chess
theories, and thinks 2. Qh5 is the best move as it is the longest move
on the board (I apologize if I have misrepresented him). I found his
ideas very interesting when starting to compose chess problems as the
longest move of a Q,R, or B is often the key or a try as it is
aesthetically pleasing to the eye. He promotes this opening even in his
schlastic chess coaching; I think the name deservedly goes to him,
despite the fact that someone else played it in 1957, to say nothing of
1857 or 1757....

He wrote a book on this that I have not been able to find; it was of
course self-published. Sometimes theories like his have limited
applicability (one of my colleagues is an expert in vector analysis,
and when I discussed what I knew of his theories, he said they sounded
like the usual oddball theory(ies) with just enough truth to convince
the innovator, but that there were definitely some valid points he was
making).
