depends, your strengths vs his weaknesses. Don't you hate those answers but it is true.

ok for example see Mayweather vs Corrales. Ok everyone saw Corrales as the puncher BUT Mayweather was faster, had better defence, was able to potshot and get outta dodge.
Hit, move, angles, don't allow him time to get set and pummel you. Stick that jab in his face like you mean it.

If they want to work at range, you work inside, clinch, shoulder nudge, offset their timing. Working on the inside and tying your guy up seems a lost art and I'm not talking at Hatton style wrestling tactics.
