小盲跟注站频率（小盲跟注站频率）

Term Meaning

The small blind calling station frequency is a quantitative metric that describes a small blind player's passive tendencies. A "calling station" refers to a player who tends to flat call (limp) into the pot with many hands preflop, rarely raising or folding. This frequency is usually derived from sample statistics; for example, in 100 hands, the proportion of times the small blind player calls when there is an open in front.

Strategic Significance

• Relationship with Exploitative Strategy: When the small blind calling station frequency is high, it indicates that the player calls too passively in the small blind. The big blind or later players can specifically raise with a wider range to isolate the calling station and exploit its passivity for postflop value.
• Positional Considerations: The small blind is inherently a disadvantageous position, and the player has already invested 0.5 big blinds. An excessively high calling station frequency suggests a lack of aggression in this position, making the player vulnerable to squeezes. Skilled players tend to adopt a tighter calling range in the small blind and prefer to raise or fold more frequently.

Typical Application Scenarios

In opponent data, if a player's small blind calling frequency exceeds 40% (example value), they can typically be classified as a calling station. Against such a player, the button or big blind can widen their raising range and increase their postflop continuation bet (CBet) frequency, since calling stations often passively chase draws or top pair.

Related Concepts

• Preflop Raise Percentage (PFR): The opposite of small blind calling station frequency is raise frequency; high PFR corresponds to low calling frequency.
• Fold to Flop CBet (F-Flop): Calling stations are often less likely to fold postflop, so they have a low fold-to-flop rate.
