nut-advantage
RangeAliases: 坚果优势, nut advantage
Nut advantage means your range has more top-end combos than the opponent's. It determines whether overbets and polarized large sizing are available to you.
Nut advantage means your range has a higher density of top-end combos (close to the nuts) than your opponent's. Together with range advantage, these are two independent dimensions that imply different strategy choices.
Detailed Explanation
How to assess nut advantage: list the "top 5-10% combos" on the current board (sets+, top two pair+, nut draws), then count their combo share in each player's range.
Classic examples:
- K72r board: both sides have similar set probability, but the raiser's top two pair (KK, 77, 22 sets) density is higher — slight raiser nut advantage
- 9-8-7 board: the raiser rarely has 65, 76, 87 two-pair / set combos (EP folds these), so the caller has a clear nut advantage
- A-high board: nut ceilings are similar (both can have AA, AK), so nut advantage is ambiguous
Strategic implications:
- Whether you can overbet: you need nut advantage to overbet — without top-end combos, there's no value range to support it
- Polarized sizing: the larger the nut advantage, the larger the polarized bet size
- Balancing the bluff range: use the top-end combo count to compute the acceptable bluff combo upper bound
Strategy matrix:
| Range advantage | Nut advantage | Recommended strategy |
|---|---|---|
| Yes | Yes | Large size + overbet |
| Yes | No | Small-size, high-frequency cbet |
| No | Yes | Polarized bet (large or 0) |
| No | No | Check more |
Common Use Cases
- Judging overbet eligibility: is your top-end share dense enough to support the large size?
- OOP defense: when the opponent bets large, ask "do they actually have nut advantage?" — if no, lean toward calling or raising
- Range design: in 3bet pots, the raiser usually has nut advantage, which drives the large-cbet strategy
