Master and Teacher tend to differ in their recommendation, so there's no standard way to improve your strength in playing chess:
Lesson #1. Learn to appreciate the way squares link up vertically, horizontally, and diagonally. Color, can be important, for it easily. Suggests diagonal lines of force. The dark color of e7, for example, may suggest an attack from a3, a square available to White's Queen Bishop. likewise, think of specific squares as corresponding with ranks and files. The square e7 for example, can be attacked from the seventh rank and e-file ( or King-side). Practice by closing your eyes and visualizing an empty chessboard. Choose a starting point and go from square to square, identifying colors, connective route, square names, and so on, Do this often and you should naturally imagine converging lines of attack in your own games.
