-Don't play his game, don't try to be faster.
-If he moves a lot, don't chase him, unless you have very good footwork and you are able to corner him.
-Watch for the feints, usually they like to use them lot.
-Be patient, you will get hit but try no to be frustrated. Usually they will slow down in the later rounds. (and you can help it with some lows and liver shots)
-Counter hard.
-Clinch the fak out of him.
-They usually engage from a bigger distance, meaning they will have to close the gap with a step in. Learn to see it and to react to it, not to the strike coming after.
