Believe it or not, it really wasn't that difficult to pull off. It just took me a little while to see it. I knew that with follow, I was going to hit the 7 thin. So, I just took that into account, and put some right on it to get on the correct side of the table. Actually putting the cb right where I pointed was a nice result of my subconscious shooting the shot, luck, and trying to stick it to my opponent. Sometimes, once in a while, things just come together just right.
The big thing to learn here is to check where a stun shot will go, and where a follow shot (30 degree rule) will go, and then plan from there. The 7 going surprised me, I hadn't even considered where it was going after I hit it because I wasn't sure exactly where I would hit it. But, I knew at the speed I shot it, it wasn't likely to get in any trouble with another ball. This was in a match to get in the money. I had lost my first match by my opponent taking two unbelievable flyers on the 9 and actually making them. Then, he runs out, dogs the 9 by hitting the points of the pocket. It bounces back and forth like a pinball machine and finally stops. Two seconds later, it drops.
That was the last time I let a weaker player have a shot at anything if I could help it. Which is why I felt I had to go for this shot.
