Chess Moves

I found this elsewhere on the net and found it interesting as I'd never thought about it:
I have heard it explained that, within chess, the movement of the pieces represents how their loyalty is split between the Church and the Crown. Orthogonal movement represents political (Crown) affiliation, and diagonal movement represents religious (Church) affiliation.
So, Bishops are exclusively loyal to the Church, while Rooks are exclusively loyal to the Crown. The King and Queen serve both, but not at the same time. Pawns move at the command of the Crown, but fight for their Church. Knights, with their code of chivalry, are sworn to serve both equally. So the Knights' L-Shaped movement is actually a political action combined with a religious action.
It may be utter hokum, but it makes a surprisingly good explanation.
