Kodokan Judo

One of the principles of judo is that a stronger opponent can be defeated by turning his strength against himself. Professor Kano explains how in yielding there is strength: “Suppose we estimate the strength of a man in units of one. Let us say that the strength of this man is 10 units, whereas my strength, less than his, is 7 units. Then if he pushes me with all his force, I shall certainly be pushed back or thrown down, even if I use all my strength against him. This would happen from opposing strength to strength. But if instead of opposing him, I leave him unresisted, withdrawing my body just as much as he pushes, at the same time keeping my balance, he will naturally lean forward and lose his balance. In this new position, he may become weak (not in actual physical strength, but because of his awkward position) as to reduce his strength for the moment, say to 3 units only instead of 10 units. But meanwhile I, by keeping my balance, retain my full strength, as originally represented by 7 units. Here then, I am momentarily in a superior position, and I can defeat my opponent by using only half of my strength, or 3 1/2 units against his 3 units. This leaves one-half of my strength available for any other purpose. If I had greater strength than my opponent, I could, of course, push him back. But even if I wished to and had the power to do so, it would still be better for me first to give way, because by so doing, I should have greatly saved my energy and exhausted my opponent’s.”
