There are several important points to watch in the standard or teaching application of this movement. We begin by having the opponent grab your right wrist and attempt to pull you toward him. Here the first important point is the off-on effect. When you turn your waist to your left and open your right fist, you create momentary slack by following your opponent’s pull, but you immediately remove that slack by turning your waist to the right and beginning to shift your weight back. If you err by pulling back against the opponent’s pull, you will create mutual stagnation, a situation of force against force, and you will have abandoned Taijiquan. The second important point to remember is that the point where the waist turn changes from left to right is not a stop-go movement. It is a small semi-circle of continuous energy. If you execute these two points correctly, your opponent will suffer a whiplash effect. The third point is that your left arm moves forward in strong peng, which should break the opponent’s grip, but if it doesn’t, it will likely break when you turn your waist back to the left and bring your chest square to the front.
Apparent Close-up is similar to Play Guitar in employing the initial creation of slack by following an opponent’s pull and then removing the slack with an off-on technique.
