Intercept with a single direct attack
How many times have you practiced your lead straight? If you are practicing anything from the JKD side of combative antagonism, then you have to work on intercepting with that straight lead off.
The punch should come from the ground up through the long jab structure.
Do you know what I am talking about? Come find out. Or get yourself a dummy and do over 10,000 repetitions of a straight punch to the nose or under the jaw.
Try it out, let me know how it goes if I motivated you to try it.
