Some things you will need to know before you do this:
Flowing
Offense
Defense
Weighing
Lay, flay, tech debate
Round vision is seeing what is happening in the round and acting accordingly. One important thing to note is that PF is a time game– if you have more time to get more of your points across or have more time to explain your points better, you are at an advantage. So how do you win this time disparity?
Offense
Look at which argument your opponents have put the least defense on– it will take less of your time to have to frontline.
OR if you have a set strategy and collapse on the same argument every time, then make sure you set up the round so that you are not at a time disparity.
Defense
Look at your defense on their side of the flow. If they undercover some of your responses or drop one, then you should extend those on their side because you have the time advantage since they undercovered it.
Just look for the defense or responses that make you most likely to win.
