Yes, his “Magnum Opus, Summa Com Laude”.
Also worthy of note are his magazines
The Square World 1966/67, and
A Game of Draughts 1946/47.
The latter includes a devastating critique of a booklet by Herman Hoogland (Utrecht) in which a new form of Draughts was proposed,
based on a hodge-podge of the rules from several variants of the game, such as horizontal and vertical moves, backward captures, long kings etc.
It also contains a brilliant series entitled
The Last Hundred Moves, written in catechism format (question and response) dealing with the End Game.
I have no doubt it was inspired by the Ithica chapter in Ulysses.
(Brings back memories from days of yore, when every schoolchild, growing up, learned the Catechism off by heart.)
P S Also reminds me of an old phonetical joke question:
What kind of toothpick would a non-believer use?
Answer: A gnaw stick.
