What is the All in One (AO) drill, and how does it work?
“All in One” is the ninth Billiard University Playing-Ability Exam. It consists of a set of 15 break-and-run challenges of increasing levels of difficulty. The goal is to pocket a given number of balls in rotation into a selected corner pocket with as few strokes as possible. No rail contact is required on any shot, and you can use multiple strokes to pocket a ball. A detailed explanation can be found here:
And here is a complete video demonstration of the progressive/adaptive version of AO:
A fun scored variation of AO is the AO 100 Challenge:
In the scored version of AO 100, you run through one rack at each level, starting with 100 points and deducting points left on the table at the end of each runout attempt. Here are the Detailed AO 100 Rules:
AO 100 is an alternative scored format, where you start with 100 points and attempt to run one rack at each Level, deducting points for the number of balls left on the table after a scratch or after reaching the maximum number of strokes for the Level.
- Your video must be a continuous run with one rack at each AO level in order.
- Start with 100 points and deduct points for balls left on the table after each rack.
- The rack ends after a scratch or foul or after reaching the maximum number of strokes for the Level.
- If a ball is pocketed with a scratch or foul, it does not count.
- The challenge can be done on any table size.
- To submit an entry, just post or email your name, score, and video link as a comment on the AO 100 Challenge video.
See the AO document for all other rules and instructions.
