Develop strong transverse power
It will help you land solid hooks and upper-cuts. When I take on taller guys, I cover up instead of jabbing to get inside, but once inside I wait for one of his hooks (since he can't throw straight shots) and then counter punch. My power range is right on and i am still too close for him to hit with any power. I do this for mma, but it still works really good for boxing, too. Twisting crunches, etc. Transverse power is all in the twist.
