So you're fighting a counter-puncher. Cutting off the ring is always an essential. You'll want to utilize feints to get him to react. Then you want counter him. It could become a sort of a stinker as far as action, but it will get him into your rhythm instead of you into his. Use your jab not only to land scoring shots, but to also get him to try to counter it. Stomp your foot, look at his body with a feint and come upstairs, whatever will get him on your page. Is he a southpaw? Try using your jab and then slipping. If he fires back, then you're ready to do the same.
