A common mistake is that after you have taken up the slack and are in and have an action on O, you then let go to attack somewhere else. Once you are on, and your attack is there, don’t retreat or change anything, just continue to apply that action, and then ad another element (most commonly a rotational action) – don’t push him here, and then let go to jerk him there. If your energy is going into O at point A, don’t stop and start putting energy in at point B, instead keep point A going and ad energy at point B. This avoids telegraphing your intention to O. When the first action remains smooth and you ad, your intention is hard to discern and he will be surprised by the addition of the new energy. Once you have two going, ad a third and so on.
