I agree with a lot of what Sento said.
With a jab, you can either do two things: catch it, or make it miss. Otherwise it’s going to hit you. So if you don’t want to catch it, you’re going to have to slip it, and the best way to convince a guy not to throw it is make him hurt every time.
It’s hard for me to give you a stance-vs-stance breakdown, since I’m a southpaw and usually moving with righties. But that being said, there’s a lot of ways for me to counter it: outside slip/throw the overhand 2, outside slip hook body/hook head, inside slip 2 body or 2 head, etc. If you’re talking footwork wise, my key is going to be keeping my right foot outside your left, which, if I do it effectively, is going to nullify a lot of your punching power.
For you though, Sento is right, the best idea if probably going to be a combination of feints and footwork. You want to get his mind off of thinking about throwing that jab, and onto wondering just exactly what you’re planning. That can be accomplished by anticipating the jab and feinting down like you’re going to go to his body - see how he reacts. Do it a few times. Watch what hand drops, what he closes off, then hit him there.
Another one is the Mayweather binoculars-type one - keep those gloves up and around your eyes, and just totally nullify him scoring ANY sort of points with his jab. As I think Donny said in the other thread, May has a talent for totally taking away your main weapon, and forcing you to do shit you don’t want to do. Do that to the other guy - take away that jab as a scoring punch, and make him drop down and jab to the body instead. Then you know where he’s going, and you can place your counter punches in anticipation. If your timing is good, you can catch him here.
Another is to keep your lead hand out a little bit and try to “smother” it. It’s kind of similar to what Mayweather did to Guerrero, just not as easy because you’re fighting another righty instead of a lefty. You’ll see Marquez do this a lot - keep his left hand up and bobbing in front of his face - and it tends to take away the ability to get a clean jab in on him. This works well if you’ve got fast hands and can catch his and shoot yours over the top in the same motion (I can’t, but maybe you can) or you can throw a lead right just after contact.
Also, as Sento said, maintaining control of the distance is going to be of crucial importance. The jab is only effective in scoring from a certain range - too close or too far, and it’s just another miss. So if you’re an infighter, work those slips to get inside and stay in the pocket with him, and if you’re a distance fighter, use feints and draws to get him to throw it when you want, so at least you know where it’s going to be and can counter effectively.
