Hi OMGWTF,
One basic way (against an orthodox fighter) is to keep/maintain your lead (right) foot on the outside of your opponent's lead (left) foot and pump out single and double jabs in a counterclockwise direction (i.e. circling away from his rear right hand) to establish/retain the initiative, keep him on the defensive, and to set up your offensive bursts.

Hope this helps...

Take Care,
Lito
