You never mention if your nemesis comes at you in straight lines or what? Have you learned how to sidestep yet? See, the secret about movement in a boxing match is this; you have to be near enough to punch him back. That small ring is actually a boon, not a bane; otherwise you might convince yourself of some untruths about what it means to "stickan'move" Now if you bend your knees jab to his chest- this will keep him off you. But keep something in mind. Every punch you throw can and will be used against you by this guy. If you jab while he's too far out he gets to time you and find how long your arms are. Almost every short busy inside boxer is adept at slipping jabs to get up close, and loading up hard blows gives him time to get close enogh to smother them ( check this, my friend. Sometimes a savvy fighter wearing headgear will take a punch to the head but, by being up close will intercept it at such a point so as there weight isn't behind it yet. This trick, of course, stops that from happening, can upset your balance and convince you that you can't get his "attentiion" witha punch) So I would suggest feinting, drawing his lead and countering. Take the time to look up sidestepping in a How To... boxing book - I'm not confident that I can accurately define it. If needed I'll try later-because that will get you out of his way, but in range to hit and not be hit. Once more, turn your left shoulder well in and target certain parts of him. For instance. the right uppercut is a natural counter for left hopoks to the body. If you try to elude him by scurrying around the ring, you won't. What will is him getting caught with hard hooks and uppercuts when he avoids the jab and landing a few hard punches under the heart or to the liver in close.
