OK I'm trying to get my head around this. I don't think I have any hope of understanding how t works for a southpaw just yet so i'm going to dumb it down for myself.

Are you saying that as an orthodox if I jab their right hand - say step in with the jab front foot only - step that foot out out when they respond - then i can go back in again and be inside. So effectively they have made up the distance for me because they thought I was much closer?

I kinda get that jabbing to the right side of their head as they jab might also help because if they drop or their right hand or overreach with their jab - which is easy to do - they are wide open. It doesn't seem to need a big slip to avoid the jab either - at least it seems that way for me in sparring lately.

Am I on the right track or way off Scrap?
