This decided and probably decisive advantage possessed by White can be minimized only by correcting a mathematical blemish in the game of Chess as at present constructed; which blemish, there is reason to believe, did not originally exist. This imperfection seemingly is the result of unscientific modifications of the Italian method of Castling; which latter, from the standpoint of mathematics and of Strategetics, embodies the true spirit of that delicate and vital evolution. To the mathematician and to the Strategist, it is clear that Chess as first devised was geometrically perfect. The abortions played during successive ages and in various parts of the Earth, merely are crude and unscientific deviations from the perfect original. Thus, strategetically, the correct post of deployment for the Chess-King is at the extremity of a straight line drawn from the center of that Grand Strategic Front which appertains to the existing formation. Hence, in the grand front by the right, the King in Castling K R, properly goes in one move to KKt1, his proper post. Conversely, in Castling Q R, he also should go in one move to QKt1, his proper post corresponding to the grand front by the left. Again, whenever the formation logically points to the grand front by the right refused, the King should go in one move from K1 to KR1. When the formations indicate the grand front by the left refused, the King should go in one move from K1 to QR1. In each and every case the co-operating Rook should be posted at the corresponding Bishop’s square, in order to support the alignment by P-B4, of the front adopted. The faulty mode of castling today in vogue clearly is not the product either of the mathematic nor of the strategetic mind. The infantile definition of “the books,” viz., “The King in Castling moves two squares either to the right or to the left,” displays all that mania for the commonplace, which characterizes the dilettante. All that can be done is to call attention to this baleful excrescence on the great Game. Of course, it is useless to combat it. In the words of the Count de Saxe: “The power of custom is absolute. To depart from it is a crime, and the most inexcusable of all crimes is to introduce innovations. For most people, it is sufficient that a thing is so, to forever allow it to remain so.” Says the great Frederic; “Man hardly may eradicate in his short lifetime all the prejudices that are imbibed with his mother’s milk; and it is well nigh impossible to successfully wrestle with custom, that chief argument of fools.” Also bearing in mind the irony of Cicero, who regarded himself fortunate in that he had not fallen victim to services rendered his countrymen, it suffices to say: The true Chessic dictum in regard to the double evolution of the King and Rook should read:
