As you can see, I like to make sure all three balls are in a direct line between the opposite corner pockets. The first object ball is one diamond out from the short rail.

The cue ball is near the object ball, but not frozen. A half balls width is plenty of distance. Make sure it's close enough so you know you're going to pocket this ball too.

From the way I'm standing, I aim at 12 o'clock. Give it a nice firm masse stroke to get it back to the other end of the table. There's no real trick to this shot, just keep your bridge steady.
