Last night Pat lent me a copy of Israel Regardie's The Golden Dawn. I had read this book years ago and wasn't expecting to find much substantive information on Enochian chess. Surpise! Nestled towards the back of the book I found about a dozen pages dedicated mostly to the magical aspect, but with some substantive information on the game play, including a short treatise penned by MacGregor Mathers! Regardie confirmed two of the starting arrays as presented by my primary source, Zalewski. Mathers also confirmed the unorthodox queen movement. This material prompted a rewrite of several passages in my article. I'm going to the library today to see if Ellic Howe and his Magicians of the Golden Dawn contain any additional surprises.
