Place your hand on a partner and apply some direction with a intention which makes sense (avoid just placing your hand, it makes little sense). have the partner close his eyes and move so he does not disturb the hand and arm by moving it but still supports it there with some part of the body (it is important to keep the support so you can guide the partner where you want them and to know where they are through the contact) and move so you are free and place a hand on them in the same manner. move without stop minding to align your body through the four points of the shoulders and hips so you can navigate yourself wherever you are during the drill. Think of a hand coming at you to strike at your temple. If you guide it with a little support (tension) in the direction of the hit and move away you are in control of yourself and can control the other as well. If he feels the change than he will change his intention and you will be forced to calculate again. Make things simple and short so you can go home. Avoid fancy moves and just walk.
