Hi,
you might know a few things already, but here's my focused analysis. As many do seem to understand me as a hostile person - I want to state all that I write is so you have another opinion/look to understand your game and get stronger afterwards.
First, please don't break with your playing cue. It will only ruin (compress, harden) your tip. Use a house cue or a break cue here.
On almost all shots you can see your cue tip wobble. This can be adressed with proper preshot routine (go and watch Tor Lowry's videos and follow them to the letter at first).
I suggest (as a starting point) to line up the cue as level as possible to the cloth (90 degrees, do not stab down at the cloth on unhindered shots), then look at the cue ball and choose your aiming point with the tip and have a
few loose, slow and shorter aiming strokes if you really hit it and have a look at the tip if it moves strictly forward, no up and down wobble allowed. Keep bridge 100% stable now.
Only afterwards focus the object ball and where you want to hit.
On the 2 and 3 you can see that you are really gripping your cue tightly. The lighter you hold it the greater your precision will be. Try having it
lay on 3 fingers, the thumb not really pressing against. It's more of a cradle. Again shown in Lowry's videos.
You also seem to twist your holding hand - very evident on the 2. This speaks of unnecessary force in your hand. Try relaxing as far as possible, your cue is not going to run away
One thing that bugs me
personally is your impersonal, absent chalking style. I assume you're not on the clock - have a look at your tip, apply chalk the same way a woman would do with lip stick: focused,
only where needed (small spots missing chalk after extreme spin shots), slow strokes, proper angles (use both outsides and insides of the chalk cube).
Snooker players do that very nicely and in a relaxed manner, that's the one you want to copy.
Sidenote: With BlueDiamond or Magic Chalk I would've chalked once before a 9 ball set and never in between :thumbup: You do not have to chalk after each shot.
Cheers and happy improving!
