What makes it an either-or choice? You could ask the same question about discussing pool on a pool forum.I shake my head and wonder why people wouldn't rather just play the game and learn on the table, rather than chase the math.
Ya know... I never considered myself an 'old school-ish' player. ...and maybe that not the right designation anyways.
However, every time threads start dipping their toes into the science of the game. I shake my head and wonder why people wouldn't rather just play the game and learn on the table, rather than chase the math.
Don't mean to crap on the science crowd. Just saying that some decent players don't even consider the tangent/carom/coriolis calculations or whatever when getting down on the shot.
I applaud the efforts and content none the less...
Fair enough...lolWhat makes it an either-or choice? You could ask the same question about discussing pool on a pool forum.
I'll have to check this out tonight. I feel like aiming is something should know, even if I just use it as a reference and not a "how to" if that makes sense. I get lost in the weeds reading about aiming on paper (pixels?) only, so having someone performing it while explaining might help.Hello AZB.
Let me introduce myself for those that not know me first. I am from Finland but been here AZB for some time.
I am all around Billiards(Pool,Snooker,Finnish Kaisa,Russian Pyramid and little bit Carom too) player, table mechanic and pool/snooker coach. I have been playing 25 years and always been one of top players of Finland but never got chance to try turn pro.
I have YouTube Channel called Poolmanis where i have videos and some are little bit instructional but never put effort to do those properly. There is more like drills, Ghost matches and other random stuff, whatever. Also my content is probably not so lower level friendly. Dunno.
Anyways. I see often here threads about people want to learn and improve their game.
I just hesitate to put effort to making real instructional videos because my channel is not big enough for getting any money from effort.. yet.
I ask if there is interested players to buy course of my aiming methods if i make 5-10 videos to cover all tricks I have found over the years?
My own aiming system is combination of fractional aiming, SVB-shaft aim, Carom angle help for aiming and some other tricks too. Also I believe everyone who is serious to getting stronger should learn usage of table geometry for estimating cut angles better.
Sounds stupid? Maybe it is but it works for me and for my students. I also have different ideas for other aspects of learning game. One main theme of my coaching is skill isolation while practice and then getting it part of package slowly.
Ps. I am also planning to do series : from beginner to pro level, where i would start series from start and slowly getting more advanced topics.
Every Junior player that I coached longer period of time is at least Finnish Champion or some have European Champion medals too. I think 5 players so far. Also my little sister started to play after 23 years break and last year she got picked first to European Champion national team in women. Too bad she missed those EC 2020 due Covid.
Last night I was reinforcing my memory because I am little rusty now on Pool. I did take video about my aiming practice session. It is about 1 hour long one take video where I practice 10, 15, 20, 30, 38, and 45 degree cuts. I forgot to take refresh break after 30 min so i got tired and did not shoot 60 degree cuts. What i also normally do.
Video have subtitles here and there to make little insights about training etc..
Video is not really instructional. Just my practice session, but i decided to share it as a teaser if people are interested to learn from me(so i did not have my mic with me). I talk sometimes there but i am not sure if audio is any good there.
The above is way too easy... You must complicate that right now.I have no idea how I aim, tbh. Whatever I do I'm sure fits into something that's been described before. Ghost ball? I visualize the contact point I think I need to hit on the OB, then walk into the line that goes from the center of the cue ball to that contact point, and go from there. I almost never consciously adjust for english, and I use standard maple shafts.
I'm pretty sure that's how all aiming works, regardless of your "system" for getting close.I remember someone posted an explainer of how we probably have mental "shot pictures" that we try to replicate when setting up, regardless of what system we think we use. That is probably the best description of how I aim.
It is pretty much still same what i do. I aimed "normal" way for years and I was making balls okay. After 7 year break from game (rheumatism made me quit) I was wondering how snooker pros are so consistent and I remembered old snooker book about half ball cut importance on colors. I just expanded same approach to other cut angles too. Only thing why I decided to try all aiming tricks and systems was because I was too much feel player that had really high gear and really weak B-Game. Nowadays I feel my game is a lot more solid on B-game too because I have little more systematic way to aim and practice aiming.I'll have to check this out tonight.

I estimated them from Bob's plot as 1/8 -20 degrees, 1/4 - 27 degrees, 3/8 - 32 degrees, 1/2 - 33.5 degrees, 5/8 - 33 degrees, 3/4 -27.5 degrees, 7/8 - 17 degrees.Here's the plot with the 1/4-3/4 overlaps highlighted. (The cut angle degrees are approximated by eye.)

That would mean (if I understand you) that all CB carom angles would be equal to their cut angles but on the opposite side of the "shooting line path". We can see from Bob's plot above that's not the case - for instance, a 30° (half ball) cut has a CB carom angle of 34°. The thinnest cuts (close to 90°) have carom angles close to 0°....If one formed an isosceles triangle from the center of the ghost ball, with one leg extending the shooting line path (i.e. extending the line from cue ball past the ghost ball), with equal legs of two diamonds (25"), the length of the base of the triangle would accurately predict how far off the shot line the cue ball would be at 2 diamonds after contact for a rolling cue ball. Is that correct?

Sorry, I think I asked the question in a confusing way. I've seen the Dr. Dave link. I'm asking a question that can probably be derived from his video if I was better at math. But, rather than determining the deflection angle, I'm trying to determine the distance the cue ball will be from the shot line at some predetermined point along the deflection line (in this case, 2 diamonds length) when that deflection angle is one of the 1/8 ball increments.That would mean (if I understand you) that all CB carom angles would be equal to their cut angles but on the opposite side of the "shooting line path". We can see from Bob's plot above that's not the case - for instance, a 30° (half ball) cut has a CB carom angle of 34°. The thinnest cuts (close to 90°) have carom angles close to 0°.
Take a look at this recent thread (Rolling-Cue-Ball CAROM ANGLE SYSTEMS), and especially at Dr. Dave's page linked there, for good info on this topic.

I think so too. You're essentially asking if the base of an isosceles triangle is equal to itself.I think what I'm asking must be true
I was really trying to check myself that the base length could be used to predict cue ball position. Along the way, I suspected it had to be true mathematically. And just to verify, 1 = 1, right?I think so too. You're essentially asking if the base of an isosceles triangle is equal to itself.

JV...and ignoring the "math" is why they will always remain just 'decent' players, as opposed to great players.Ya know... I never considered myself an 'old school-ish' player. ...and maybe that not the right designation anyways.

Don't mean to crap on the science crowd. Just saying that some decent players don't even consider the tangent/carom/coriolis calculations or whatever when getting down on the shot.
I was asked Bustamante to shoot a halfball hit and go three rails. I have to explain it to him in Tagalog what a half ball hit is. he just ignored me. Was he just a decent player?JV...and ignoring the "math" is why they will always remain just 'decent' players, as opposed to great players.

People can learn to play the game thousand different ways.I was asked Bustamante to shoot a halfball hit and go three rails. I have to explain it to him in Tagalog what a half ball hit is. he just ignored me. Was he just a decent player?
Example : hair thinner than half ball with natural roll will make cueball and object ball travel same distance..
