Index plays
No publisher we found states a numeric Omega II index table.
This system has no published table of index plays, so none is shown.
| Measure | Value |
|---|---|
| Index | n.a. |
| Gap status | No source we found publishes this table. |
The gap recorded below is a finding, not an omission.
No source we found publishes a per hand Omega II index table.
One source states that the basic set changes play at two thresholds only.
The trainer therefore drills the Omega II count and the true count.
The trainer falls back to the sourced Hi-Lo indices and labels them as Hi-Lo.
Basic set thresholds
The two thresholds below are the only published statement about the basic set.
| Measure | Value |
|---|---|
| Reduce aggression at or below | -6 |
| Increase aggression at or above | +6 |
Three independent publishers agree on this tag set.
Ace side count
Omega II is ace neutral, so betting needs a separate count of aces.
| Measure | Value |
|---|---|
| Side count rank | A |
| Required for | Betting |
