Grandmaster Wong demonstrates how to open or close an opponent

One effective way to stop a pressing attack is to grip the attacker's hand. So, if you wish to employ the tactic of pressing attack, you need to know how to release your opponent's grip if he successfully applies it on you, and continue your attack. You must close your opponent adequately when you press an attack, though sometimes you may open him. You must also have penetrating reach. Your victory is enhanced if you also apply the tactic of true and false.
