not an instructor
but how about loosening your butt grip?
relaxing your grip might help relax your mind
it also seems more difficult to "poke" with a light grip
and if you happen to shake, I think the shaking would show up less when the grip isn't as tight
good luck!
Actually my grip is on the lightest side possible but what you said makes sense. I have fixed the issue, though the explanation may or may not make sense.
Yes this is very useful. I have already realized that this is part of the issue as well as the vision of the shot I have. I have a wonky neck that hurts more and more the longer the shot is. Since I can't effectively angle my head up I am going down on the shot at all different heights to try and compensate it. And I think my brain is realizing it is off and trying to compensate. So I need to dial in a more consistent set up procedure and taking out the slack will help with that. Since realizing this I have been better but need to dial it inOne of the best bits of knowledge on the yips I ever came across came from Gravity Golf's David Lee. He explains that slack in joints can often lead to spasams in muscles to compensate for a broken kinetic chain. While there def seems to be a mental component, it would be wise to address any physical reasons for the appearance of yips in your game. David Lee's examples are obv highly geared towards golf but the principle of removing slack can be easily applied to pool. Esp if you're the type not to be really down on the cue, you can develop an inconsistent relationship between the arm and body. Being all the way down like snooker players sets the shoulder rotation near if not full max which takes out all slack and leaves no wiggle room. If, however, you have your chin a few inches off the cue and a high shoulder you can achieve the same look to your stance and setup while carrying varying levels of tension in your shoulder and an inconsistent feel to your stroke. Any time that shoulder tension is too low you lose connection and can snatch at the shot. A fix for this would be to be mindful of your posture through your back in your setup or to preset your arm position in your preshot routine by either forcing your elbow back or bringing it up as high as it goes when getting down, or simply trying to keep the longest stress free distance from your head to your elbow... any of these three will keep the relationship between your body and your cue arm consistent and remove slack from the shoulder joint which should at least make the yips less likely and eliminate a physical cause of them.
