Sparring versus Puzzles
To achieve the goal of having a competed jigsaw puzzle, you must choose the proper puzzles pieces and then place them into their proper positions. It is a waste of time to try to fit the wrong piece into an open puzzle position. When sparring, to achieve the goal of winning, you must choose the proper weapons and then fire them into the proper targets. It is a waste of time to fire the wrong weapon at the wrong target. A wide foot may not get through a narrow opening in the opponent's defenses, while a narrow fist may penetrate into the opening.
