Shoot this shot on both sides of the table. All you have to do is scratch. The cueball must be frozen on the rail. I tried this on a very tight table, and it's alot harder than most people think. You must have a straight stroke to do it. If the cueball comes off the rail and still goes in, don't cheat yourself. Try to have the ball hug the rail all the way to the pocket. Can you do it?
