Vincent DeGruy has adapted the knowledge from books about warfare and one-on-one samurai dueling [from the Art of War (Sun Tzu) and A Book of Five Rings (Miyamoto Musashi)], combined it with 10,000 hours of chess play, and created a masterpiece in general strategic thought with an emphasis on chess.The adventures consist of amusing stories of an undisciplined youth narrowly avoiding disaster with his younger brother followed by numerous slave labor jobs for the state of Texas while developing the Unbeatable strategy which came to be known as the DeGruy Variation.
