Poker Term

CO位河牌偷池静态（CO River Steal Static）

Refers to a strategy of betting on the river from the CO position cutoff with a fixed range (usually all unimproved hands with showdown value or specific bluffs) to steal the pot.

Overview

CO River Steal Static is a static stealing strategy in poker for a specific position and street. The CO (cutoff) is one of the last positions to act preflop (only behind the button), giving it positional advantage. This term emphasizes that on the river, the CO player bets with a fixed range rather than adjusting based on opponent dynamics.

Strategy Principle

On the river, when the CO player judges the opponent's range to be weak (e.g., checking shows weakness), they can bet to force the opponent to fold and win the pot. The static strategy means the betting range is predetermined, typically including two types of hands:

  • Value hands: made hands that can beat the opponent's calling range.
  • Bluff hands: specific combinations of unimproved draws (e.g., failed gutshot straight draws or failed backdoor flush draws) that have no showdown value but are used as bluffs.

The static strategy contrasts with a dynamic strategy: a dynamic strategy adjusts betting frequency based on opponent tendencies, table image, or history; a static strategy is based on GTO (Game Theory Optimal) balance, keeping a fixed bluff-to-value ratio to prevent being exploited by opponents.

Applicable Scenarios

  • Opponent's range is weak with a high fold rate: e.g., the opponent checks on the river, and their range consists mostly of medium-strength hands or failed draws.
  • The CO holds air but has blocking effects: e.g., holding a key card that reduces the opponent's chance of having the nuts flush or straight.
  • As part of a GTO strategy: with no special reads, a static steal ensures long-term balance and prevents targeting.

Precautions

A static steal is not optimal in all situations. If the opponent is a calling station or sensitive to steals, switch to value betting or give up. Additionally, this applies only when in the CO position and on the river; similar actions on the flop or turn fall under "continuation bet" or "semi-bluff."

Example

Assume the board is K♠8♦3♣7♥2♦. The CO player holds A♠4♠ (only ace-high), and the opponent checks on the river. According to the CO River Steal Static strategy, if this combination is within the predetermined bluff range, bet half to two-thirds pot, expecting the opponent to fold their possible middle or small pair.
