Keep them on their heels. Before the enemy makes a move, before the element of chance or the unexpected actions of your opponents can ruin your plans, you make an aggressive move to seize the initiative. You then keep up a relentless pressure, exploiting this momentary advantage to the fullest. You do not wait for opportunities to open up; you make them yourself. If you are the weaker side, this will often more than level the playing field. Keeping your enemies on the defensive and in react mode will have a demoralizing effect on them.
