"The Art of War," written by ancient Chinese philosopher, Sun Tsu, has been called the concentrated essence on the conduct of war. While thousands of years old, it has long been available in inexpensive paperback form because its tenets are timeless, unmistakably true, and still relevant. One of the important lessons from the master is obfuscation. Effective coaches of competitive sports know this lesson, and all successful athletes put it into practice every time they play. Never let the opponent know what you are up to. Hide your strengths and weaknesses. Feign right, cut left. Attack where the enemy is weakest. If the opponent knows what you will do ahead of time, actions will be taken to counter it and your effort will be wasted.
