Principle: Judgement of Distance
In politics, the saying "draw a line in the sand" stands for a boundary the opponent is warned not to cross. Ceasar crossed such a boundary when he crossed the Rubicon with his army.
Similar to the judgment of distance in the basic principles, it also concerns limits in push hands. Correct spacing between opponents, foot angle, and leg positioning are essential. This is because a set of centerlines must be established between the opponents.
One opponent's "capture" of a line of balance or centers of gravity constructs a fulcrum that creates potential leverage. The gain of disproportionate strength through the judgment of distance centerline capture, four ounces moves a thousand pounds, is a reference to determine who "wins" or "loses." More on this to follow.
