If you are making a straight lunge, then you are making a Forseen action. If you are marching down the strip making multiple feints and waiting until the final second to choose your target, then you are making a Partially Forseen action. All drills assume same-handed fencers. All ripostes with simple extension. Exercises III and IV introduce multiple parries or parry sequences.
Many fencers develop sequences that they prefer for clearing out complex attacks.
Experiment with different sequences to determine the ones that work best for you and in different situations. You should also play with the different types of parry-ripostes. These drills focus on using the middle of the blade for beat parries. Once you are comfortable with the execution of two individual drills, you can have the leader choose which set of actions to go with and mix up the drills as you go. This keeps you alert to what your opponent is doing rather than going into autopilot with a move.
