By further comparison of the terms of the Initial Strategetic Equation, select that Decisive Menace strategetically next in sequence to which the term +T does appertain; and let the Piece operating such Decisive Menace be regarded as the Corps d’armee en Menace; the Objective of such menace as the Prime Decisive Point; the occupation of such Point by such Piece as the Normal Motif of Offensive Effort, and the Logistic Radius connecting the Point of Departure occupied by such Piece and the Prime Decisive Points as the Normal direction of Offensive Effort. Provided: Whenever the term +T appertains to a Menace not so immediately decisive as another menace operated by an adverse army, column, wing or corps d’armee, but to which the term +T does _not_ appertain, then: the Normal motif of Effort is _defensive_, and the Normal direction of Defensive Effort is along the Logistic Radius between the Point of Departure of that Kindred Piece, which by the advantage of the term +A, is able to nullify the adverse most immediately Decisive Menace and that Point of Command which is the Objective of such Effort en Defence and from whence such adverse most immediately Decisive Menace may be nullified. * * * * * The second or Intermediate Phase of the Prime Strategetic Proposition appertains to Grand Manoeuvres; and the third, or Final Phase, appertains to Grand Operations. _However vast one’s capabilities may be, there is no mind so comprehensive but that it has much to learn from other minds which have preceded it, and no talent is so potential but that its development is proportional to its exercise._ _For no matter how broad and exact one’s knowledge, the application of such knowledge alone constitutes Art, and the value of such knowledge always is commensurate to the degree of skill attained in the use of it._ _Hence, there is a training of the physical senses which gives quickness and strength to the eye, the ear and the hand; a training of the nervous organism which gives courage to the heart, clearness to the brain, and steadiness to the body; a training of the intellect which fructifies in originality, ingenuity, profundity and exactness of calculation._ _Such training is to be acquired only from systematic study of the best productions by Masters of the Art, and by incessant practice with the best proficients._ End of the Project Gutenberg EBook of Chess Generalship, Vol. I.
