Do you have an understanding of what CJ means by pinning the CB?
Not sure anyone really does, including CJ. Below are just ten quotes of him explaining it.
1.Another positive attribute of cocking the wrist "hammer style," is that on the forward motion you can activate your stoke simply by closing your hand. With the correct timing the acceleration will happen EXACTLY at impact. It's also important to know that the game is played with the EDGE of the tip, must like punching with your knuckles instead of the flat part of your fist. This technique is what road players call "Pinning" the ball.
2.That's correct, anyone can hit the cue-ball with the edge of their tip, however, few accelerate in a way that creates the "Pinning Effect". You can hear the sound it makes, and it's distinctively different than normal.
3.Pinning is done by using the top, "knife edge" of the tip with the acceleration exactly at the ball. It's lethal to "stun," draw, or put "quick english" on the cue ball - it is best suited for slower or worn cloth. This requires a very precise motion with the hand and wrist immediately at cue ball contact.
4."Pinning" is similar to a Japanese martial arts punching technique - put your fist 15 degrees in and 30 degrees down and hit with two knuckles, rotating your hand at impact. This uses less mass, however the results are piercing and can do severe damage. Of course with pool you don't rotate your hand, it's done with your wrist/finger release.
5. The phenomenon of "Pinning" happens when a player is accelerating fully at the moment of contact with the edge of the tip (I rarely use the center of the tip's surface, the edge is more precise for accuracy and spin/toi)
6."Pinning" is when you contact the cue-ball with the edge of your cue with a slightly ascending blow (top for "draw," and bottom for "follow").....hardly driving the cue ball into the cloth (that would be more like a "jump shot").
7. The key to accuracy for me has always been how well I'm accelerating to the "cue ball target" with the edge of my tip (the center edge to TOI to be exact). This "Pin's" the cue ball and the path it takes is very precise......very precise indeed.
8. sound of the tip hitting the cue ball will be higher pitched....we call this "Pinning" the cue ball.
9. I've been practicing and concentrating on the Pinning action of the TIP by making sure the top/edge is extending straight through the TOI Point on the cue ball.
10. It's not how you hit the cue ball, it's the motion you use with your hand to allow the TIP make a descending blow to the cue ball.....so that it travels exactly down the path and and this is achieved by focusing on your hand motion. The tip follows what you're doing with your right hand (of right handed) and is a direct reflection of that connection. Have you notice how much action the Champion players get with very little effort?
This is not because they are so "powerful" it's because their technique is so accurate. It's like an accomplished martial artist can create incredible force with very little effort because their technique is so refined and they've eliminated any unnecessary movement or motion. In pool this is difficult to detect, but I'm sure you know it's there.
If your hand moves up slightly the tip will follow and if it moves down slightly the tip will also follow.....if the hand moves straight, the tip moves straight.....I'm certainly not saying this is complicated, I am saying this motion can be improved in most players....and as an effect their tip will have a more efficient, precise, "Pinning" effect on the cue ball.
