Awesome, d00d!
So, when I first saw the shot, I suspected you were full of it, but since I've learned several impossible shots in the past few years, I sat on my hands and posted nothing until I could get to a table and see for myself. My (bogus) belief came from the fact that I had never seen anyone play this shot, and I have seen a lot of one pocket.
I tried various angles and spins, and the most impressive set up I found is like this: Put the object ball a diamond from "your" corner pocket and a ball off the side cushion. Put the cue ball so that the two-rail bank is nearly straight except for the kiss. Play the cue ball with "helping" english and follow. In this case "helping" is on the side of the cue ball away from the pocket. Pick a fullness and shoot the shot. Note what the object ball does. If you hit the object ball too much on the pocket side, the ball won't get to the pocket, but it should be knocked back to the cushion. If the object ball is not knocked back to the cushion for too full a hit, you have to add follow or change your speed -- probably slower.
If the object ball gets to the end rail but never gets back close to the cushion, you are kissing too thin. Aim more on the pocket side of the object ball.
Once you get pretty good action, you can try different approach angles, but the aiming will be different. The object ball needs to be off the cushion to allow the cue ball to get some forward speed from its follow. Of course the farther off it is, the harder it is to drive it back to the pocket, so there is some best distance. One ball out seems to work well, but I didn't much test other distances.
I'll see if I can make a video. I was playing on a GC3 with 4.25-inch pockets and medium-old Simonis 860. The balls are fairly new Pro Cup TV balls with the measles cue ball.
A great shot to know -- thanks. I hope it comes up soon.
