That was kinda curt on my part,I can be that way
You make contact on his jab one of two way
Outside,now if you go outside your going to have to hook your armaround it,have a good defense with the other hand and hang on for dear life,because now your going in for a Philly street brawl
Make sure you maintain head to head,or head to shoulder contact,so you can feel when you should break off your own offense to block,and walk the arm you have trapped away from the ref,your looking at a fast break otherwise
Now inside,get your power hand up and ride in maintaining contact with the jab hand the whole way,you can even cheat it a little to get a hook off,by pressing on it and cocking as you come.you have to pay major attention to the right cross as you do this though,and if you get too spread open the uppercut
