Interesting if idiosyncratic thread. Guess I missed (thankfully) the AZB Holy Wars over the word "feel."
I am a relatively newbie. Had a table from age 6 to 20, then didn't play regularly for 35 years. Got back into the game 2 1/2 years ago.
As it turns out, I spent lots of time in 2023 learning the major Diamond systems. Got those Kamui Diamond slicers on my table and practiced a number of Tory Lowry drills on kicking and banking.
Why? Why spend so much time on that part of the game instead of more basic stuff? For one thing, math. It seemed pretty simple.
I also wanted to get good at kicking quickly so as not to give up ball in hand to better, more seasoned players at my pool hall.
What I have found? They work. I've played on half dozen to a dozen different tables and they work. I am pretty good at not giving up ball in hand.
Now, all the caveats mentioned in this thread by far more experienced players apply. (Every table is different etc). But I can size up a table pretty quick.
Does "feel" come into it? Of course.
Sometimes I just look at a shot now, and I can tell the math alone won't get me to where I want the ball to go.
Maybe I need a touch of sidespin. Perhaps a slower shot to widen the angle. Or a harder shot to narrow the angle. And what about when the OB is close to the rail?
I learned these variables by practicing and playing enough.
Nowadays I often do kicking and banking drills in which I purposely do not use the Diamond systems. I am trying to go by feel instinct now that I have more experience gained from Diamond systems.
That said, I still will sometimes "do the math" when playing vs opponents. Just to make sure my "feel" is in the ballpark.
I remember a video in which Jennifer Barretta said: "Everybody always says, "I kick by feel.' That's okay. You kick by feel. I am going to kick with accuracy."
Even the best pros in the world use systems on occasion. I saw Fedor Gorst visually do it several times during the World Pool Masters.
Sometimes I see pros miss badly on kick shots - and I know they are going to miss based on where they aim. I visualize where I think they should hit, and they hit somewhere else. When that happens, I wonder if they are going entirely by feel.
Naturally I would love to get good enough that I never need to use systems or Diamonds. I would just know instinctively where to hit.
But the Diamonds are a roadmap. I am not always going to drive around trying to find my way without a map.
If I feel a bit lost, or I just want to be sure, sometimes I'll just pull out the damn map to give me a little help.
