小盲位翻牌前加注-弃牌（干燥手牌）（SB Preflop Raise-Fold Dry）
A strategy or statistical indicator of raising pre-flop from the small blind with a dry hand no flush or straight draw potential, then folding when facing a re-raise from the opponent.
Overview
"SB Preflop Raise-Fold Dry" is a term used in Texas Hold'em to describe a specific action pattern for the small blind player. "Dry" here refers to the player holding a "dry" hand—one that lacks immediate made-hand potential, typically high cards (e.g., AKo, AQo) or small pairs, without flush or straight draw structures. This term commonly appears in HUD (Heads-Up Display) stats or strategy discussions to analyze a player's tendency to fold when facing a 3-bet from the small blind.
Statistical Meaning
In a HUD, this metric is usually expressed as a percentage, calculated as follows:
- Numerator: Number of times the small blind folds after raising preflop when facing a 3-bet (typically from the big blind).
- Denominator: All opportunities where the small blind raised preflop and then faced a 3-bet.
Constraint: Only counts hands classified as "dry." Wet hands (e.g., suited connectors, pairs) are excluded to avoid data bias.
Strategic Application
- Exploiting Frequency: If an opponent has a high value in this stat (e.g., >70%), it indicates they are very likely to fold when holding a dry hand in the small blind. The big blind can then 3-bet more frequently with a wider range to deny them their pot equity.
- Balancing Range: Small blind players should mix in some flat-calls or 4-bets with dry hands to prevent being overly exploited. A common adjustment is to call the re-raise with some AKo or AQo instead of always folding.
- Postflop Impact: Although "Dry" here refers to preflop hand type, when the flop is also dry (e.g., K-7-2 rainbow), combining a dry preflop hand with such a flop increases the expected value of a continuation bet (C-bet).
Example
Suppose the small blind holds A♠Q♦ (a dry hand) and raises to 3 BB. The big blind 3-bets to 10 BB. If the player's historical data shows an "SB Preflop Raise-Fold Dry" of 80%, it means they have folded in similar situations most of the time. In this instance, they fold, conforming to the statistical pattern.
Notes
- This term is not an official poker term; it is more commonly used in custom HUD labels for online poker software or in advanced strategy community discussions.
- The statistical results are highly dependent on opponent classification and game stakes. Interpretation should vary based on blind sizes and opponent styles.
