Mechanics of the Rock
Research-backed guides for the move from league night to the tournament floor.
A series of research-backed billiards guides for one reader: the serious APA league player moving into WPA, BCAPL/USA Pool League (CSI), ACS, and pro-tour play. One topic per episode. Every claim carries its evidence, every number names its source, and every episode ends with the conclusions that survive.
01 — What this series is
The gap between APA league pool and tournament pool is mostly a knowledge gap, not a talent gap. The series is that gap, closed one topic at a time, on sources instead of folklore.
You already play well. What the crossover adds is a layer league play never forced on you: formal rulesets, pro-table equipment, and the strategic adjustments both demand, with real stakes on every break and every safety. League players get put in front of WPA, BCAPL/USA Pool League, ACS, and pro-tour conditions with no map. The series is that map.
Each episode takes one competitive pool topic and does three things with it:
One episode answers one question thoroughly. It does not try to be a book. Depth plus honesty is the product. Rules differences get named, not summarized: what APA does, what WPA does, and why the difference changes your decision. Episodes are self-contained, because you read them on a laptop or a phone, before or between matches. And where the table itself changes the answer, an episode ships both the 9-foot and the 7-foot version of it.
It is not a fundamentals course. Episodes never re-explain the shots you already have. It is not a highlight reel either: no hype, no secrets the pros are hiding, no game-changing anything. Where the sources disagree, the disagreement is printed, not averaged. Where nobody has measured the thing, the episode says so in plain words. A named gap is content, not a confession.
Every factual claim in an episode carries exactly one evidence tag from the tier system below. The tag travels with the claim, in the same sentence. It is never upgraded to make a paragraph read better.
| Tag | What it means |
|---|---|
| rule | Quoted or paraphrased directly from a current official ruleset: WPA, APA, CSI, ACS, or a tour. |
| measured | Instrumented numbers: measured break speeds, table dimensions, equipment specs, simulations with a stated method. |
| instructional | A named instructor's or manufacturer's claim, not independently verified. |
| observation | Documented play: tournament results, footage, recorded patterns. |
| synthesis | The guide's own reasoning across sources. The claim is ours, and the inputs are cited. |
| anecdotal | Forum-grade or single-player claims. Useful as signal, weak as proof. |
| unverified | Appeared in the research corpus but failed verification against a primary source. Never load-bearing. |
02 — The study
The study covers the competitive layer of the crossover: aiming, banks and kicks, elevated strokes, safeties and position play, and the equipment variance that quietly changes the answer. All six companion episodes are live, alongside the flagship.
The flagship. An evidence guide to 8-ball, 9-ball, and 10-ball break strategy: placement, aim, speed, and spin on 7- and 9-foot tables, the rulesets that govern the break, and the equipment evidence, with interactive Break Lab diagrams and every claim citation-linked.
Open the episodeWhat the aiming methods can and cannot do: pocket tolerances of a few degrees, throw up to about 5 degrees, squirt of 1 to 2 inches over 50, and why every source agrees most misses are alignment, focus, and stroke failures, not aiming-method failures.
Open the episodeBank and kick systems priced by their real mathematical standing, not their reputation, plus kick safeties that refuse ball in hand, and the ruleset trap: the same kick that silently scores in APA can end your inning in CSI play.
Open the episodeThe legal jump is a rebound, not a scoop. What the elevated strokes actually do, how often pros use them, when to jump, kick, or curve, and where each ruleset draws the line, including the CSI definition that rules any curve a massé.
Open the episodeTwo-way shots, intentional fouls, push-outs, and key-ball planning: the episode where league safety habits meet tournament ball-in-hand rules. The full episode is live.
Open the episodeThe three tables you will actually meet, what a quarter inch of pocket cut and a point of humidity do to pockets, banks, and throw, and the pre-match inspection that prices a venue before you break.
Open the episodeWhat structured practice actually transfers to competition: which drills have documented value, what deliberate practice means for pool specifically, and how to build a week of practice around league nights.
Open the episodeEvery episode in the study is published, and every card links to its live folio page, flagship included. The chips carry the state: solid green for published.
03 — The backlog
What comes after the study. The scopes below are the current plan, not promises of dates, and each episode gets its own cited research document before the folio is written.
The gambling culture that shaped bank pool and one pocket, told as cited history, not romanticized myth. Documented where it can be documented, marked unverified where it cannot.
The Break Lab diagrams become a configurable simulator: game, ruleset, table size, placement, speed, spin, and rack variance, built on the anthology's measured break data with a visible model-disclosure panel.

04 — Standards
Five standards govern the series. The hub carries them so every card on this page has the same contract behind it.
A claim travels with its tag: rule, measured, instructional, observation, synthesis, anecdotal, or unverified. Tags are never upgraded to make a paragraph read better, and the tag is part of the sentence, not a footnote.
Any number, percentage, speed, dimension, or count in an episode traces to that episode's sources registry. If the sources do not contain the number, the prose does not either. Estimates say estimate, with the method.
Where two rulesets or two sources conflict, each position gets stated with its own evidence, and the strategic difference gets the analysis. The reader picks with full information.
Claims that failed verification appear only in an episode's unverified section, styled so the gap is impossible to miss. They support nothing else in the episode.
No "as we covered last time" dependencies. Where table size changes the answer, the episode ships both the 9-foot and the 7-foot version of the diagram.
