CO河牌静态4-bet（CO River 4-Bet Static）
This term is not a widely used standard poker term; it may be an expression from a specific strategy article, usually referring to a strategy of using a static 4-bet range against a river raise from the cutoff CO position.
Overview
“CO River 4-Bet Static” is not a common general term and rarely appears in mainstream poker theory literature. It may originate from a specific naming convention used by a coach or analysis software, or could be a typo. In standard poker strategy, the discussion is usually about “CO 4-Bet Static Range,” which refers to a fixed 4-bet range used from the Cutoff position when facing a 3-bet preflop, without adjusting to the opponent.
Analysis
- CO: Cut Off, the position to the right of the button, a late position.
- 4-Bet: Preflop, it typically means a re-raise after a 3-bet; post-flop (including the river), the term “4-bet” is rarely used because the number of raises is usually smaller. On the river, common raise counts are 2-bet or 3-bet.
- Static: Static, meaning the range is fixed and not adjusted based on opponent tendencies or board dynamics.
Possible Background
If this term does appear in some training material, it might refer to a fixed raise size or range used by the CO position on the river in a specific scenario (e.g., as the preflop aggressor). Given the lack of widespread consensus, it is advisable to interpret it in context.
Considerations
In No-Limit Hold'em, river raises typically have a clear strength range; static strategies are rare, and dynamic balanced strategies are more common. Therefore, caution is advised when using this term.
