CAC2 vs Hi-Lo: Is CAC2 Worth Learning?
Hi-Lo is the system most people learn first. CAC2 is a more advanced multi-level count favored by players chasing higher accuracy. Here is an honest, high-level look at how they compare — and how to practice either one.
At a glance
| Dimension | Hi-Lo | CAC2 |
|---|---|---|
| Complexity | Single-level (+1 / 0 / −1). Easy to learn. | Advanced multi-level system. Steeper learning curve. |
| Accuracy potential | Strong and proven for most players. | Higher ceiling for betting and playing accuracy. |
| Speed to run | Fast to maintain at the table. | Requires more practice to keep pace under casino speed. |
| Best for | Beginners and most recreational advantage players. | Experienced players chasing maximum accuracy. |
| Availability | Public and widely documented. | Proprietary — obtained from its creator. |
CAC2 vs Hi-Lo: simulated performance
Drawing on the CAC2 system's own publicly published figures, nine counting systems were simulated at two bet spreads (1–12 and 1–16). CAC2 ranks first and Hi-Lo last. Higher scores indicate stronger overall performance — a concrete example of why advanced multi-level counts like CAC2 can edge out Hi-Lo.
| Counting system | 1–12 | 1–16 |
|---|---|---|
| CAC2 | 23.76 | 27.84 |
| Halves | 23.60 | 27.68 |
| Zen | 23.53 | 27.60 |
| USS | 23.44 | 27.50 |
| Felt-F | 22.99 | 27.04 |
| RPC | 22.74 | 26.75 |
| EBJ2 | 22.55 | 26.53 |
| TKO | 22.29 | 26.28 |
| Hi-Lo | 21.19 | 25.04 |
These scores come from the CAC2 system's own publicly published performance comparisons. As with any simulation, actual results depend on the specific rules, penetration, bet spread, and player execution.
The honest answer
CAC2 can be worth learning — but mostly for players who have already mastered the basics. A more advanced count only pays off if you can run it accurately at table speed; otherwise the extra mental load costs you more than the higher ceiling gains. If you are still building consistency, Hi-Lo will serve you well and CAC2 can wait.
If your counting, true-count conversion, and deviations are already automatic, CAC2 is a reasonable next step toward squeezing out more accuracy. The fastest way to find out is to drill it: practice CAC2 as a custom count and watch your accuracy and speed stats to see whether the upgrade sticks.
Practice either system here
AdvantagePlay includes Hi-Lo out of the box and lets you add CAC2 as a custom counting system. Every count-aware drill works with both, so you can compare them head-to-head with the same drills and stats.
