Tournament Stack Pressure Reference
This reference expresses stack depth in big blinds and shows how much one big blind represents as a percentage of the current stack.
The percentage calculation is exact. The descriptive bands are editorial heuristics for learning—not solver outputs, ICM thresholds or universal shove ranges.
Reference table
| Stack | Learning band | 1 BB as % of stack |
|---|---|---|
| 3 | Critical | 33.33% |
| 5 | Critical | 20.00% |
| 8 | Very Short | 12.50% |
| 10 | Very Short | 10.00% |
| 12 | Short | 8.33% |
| 15 | Short | 6.67% |
| 20 | Medium | 5.00% |
| 25 | Medium | 4.00% |
| 30 | Comfortable | 3.33% |
| 40 | Comfortable | 2.50% |
| 60 | Deep | 1.67% |
Why big blinds are more informative than chips
A 20,000-chip stack has radically different decision space at 100/200 blinds than at 1,000/2,000 blinds. Big-blind normalization makes those states comparable.
Why the bands are not strategy commands
A 10 BB stack on a Double Up bubble can face very different incentives from 10 BB early in a winner-take-most event. Antes, position, payout structure, stack distribution and opponent behavior must be layered on top.
