How's he jabbing, is he stepping in with it? Now if he steps in and leads in with the jab that can give you a chance to slip it and close the gap. On the inside how does he fight, which side does he step to, how's he holding his hands, is he square shouldered or with one side forward, does he punch in between your sequences? This should all be taken into consideration so that you'll know how to better handle him while weighing the advantages in your favor.

As for your right hand if you can make him think you're gonna throw it then you can feint with it, and hit him where he doesn't expect it. Feints are based on expectations which can cause reactions. Now there are hundreds of ways to feint, it all depends on what you want him to do. You can feint with a twitch or your hand, shoulder, your can feint with your eyes/head, with your footwork (step forward::step back, feint a side-step and move in the opposite direction), shifting your weight, dropping to a crouch, sounds/breath, with a punch that you land but don't fully commit to, all of which can be done in various ways and mixed up. Some feints won't get any reactions our of your opponent and others will. The idea with feinting is to affect their expectations therefore causing them to react in a way that either gives you an opening, moves them into a disadvantageous position, allows you to counter, at the least making hesitate on particular punches and reducing their options. Feinting requires you to be observant of the reactions and changes in an opponent. It works best if you can make your opponent cautious about some of your punches so that you can use those particular punches in feint to get him to react to your advantage.

On the inside learn where to hit and set up your shots. If you want to hit his liver make sure you can get into that position and know how to make it count. A left hook to the left side of their body isn't going to affect them as much as digging a hard left hook under their ribs. Learn the other targets as well, the solar-plexus is good mark, the spleen by digging a right uppercut under their right ribs, their floating ribs are more vulnerable and can be broken by a swift hard punch, a hard right to the heart is a legit KO, the heart is behind their ribs and in your view is just few inches northeast of their solar plexus. The kidneys are an illegal target but are up for grabs if your opponent leaves it exposed.

As for counterpunching there's a lot that you can do, you can work on your side-stepping, feinting with your feet is great, practice your slip, some punches can be slipped in the same way that some punches are thrown which is useful when you are countering jabs and straights. In the end we're all counterpunchers, but the one's that do the best are usually holding all the cards.
