枪口位河牌静态四次加注（UTG River 4-Bet Static）
A mixed term, usually referring to a static 4-bet range from UTG position preflop, but "River" in this may be a misreference or a strategy description for a specific situation, not a standard poker term.
This term is not common in standard poker terminology. Breaking it down: "UTG" refers to Under the Gun, the first position to act preflop; "4-Bet" typically means the fourth raise preflop (a re-raise of a 3-bet); "Static" indicates that the strategy or range does not adjust based on opponent tendencies, remaining fixed. "River" refers to the final betting round, which contradicts the preflop timing of a 4-bet. One possible interpretation: the term might originally have been "UTG 4-Bet Static," describing a fixed, non-adjusting 4-bet range (often only AA/KK) from UTG when facing a 3-bet. However, "River" was mistakenly added, or it could describe a postflop static strategy (e.g., using a fixed range to bet on the river), though such usage is extremely rare and lacks consensus. Since the term is non-standard, it is recommended to refer to more common concepts like "UTG 4-Bet Static" or "UTG 3-Bet Static."
