Inside the full lesson
Why does AKs have 67% equity in one spot and 52% in another?
In the full lesson, you work through this scenario with interactive examples.
You've memorized that AKs has 67% vs a random hand. But at the table, AKs runs at 52% all-in vs villain's actual 3-bet range. Where did the 15% go? Into the difference between hand-vs-hand equity and range-vs-range equity. Once you see this, every "I had 65%" comment in your hand history reads differently.
What you’ll learn
- The two equity numbers every spot has — and which one matters
- Nut advantage vs equity advantage (not the same thing)
- How to estimate range-vs-range equity at the table without a tool

The two equities — and why one is a lie
Referenced activities and other examples are available in the full lesson after sign-in.
Hand-vs-hand equity — your hand vs one specific opponent hand. AKs vs QQ all-in pre = 46.6%. Useful for solvers, useless at the table because villain's actual hand is random within their range.
Range-vs-range equity — your hand vs villain's entire calling/raising range, weighted by combo count. AKs vs a 3-bet calling range of {QQ-TT, AKs-AQs, JTs} ≈ 49%.

Nut advantage vs equity advantage
Referenced activities and other examples are available in the full lesson after sign-in.
These are NOT the same thing. Both matter. Different decisions for each.
Equity advantage: your range has more total equity than villain's range. Example: on K72r, the preflop 3-bettor has 55% equity vs the caller — across all hands.
