First, hang the object ball in the side pocket. Lean it to whatever side you're shooting from. I place the cue ball anywhere between two and three diamonds away from the short rail, about a half diamond off the long rail on the opposite side.

Aim at the short rail, as close to the corner pocket as you can get. Use maximum right english. This shot isn't about power, it's about juicing the cue ball up as much as possible. You can make it easier by using a helper ball for a combo, although in one respect this will make it more difficult as the cue ball will have to clear this on its way by the first time.
