Poker Term
CO河牌五注动态（CO River 5-Bet Dynamic）
Refers to the strategic dynamic formed by a CO cutoff player making a fifth raise on the river (possibly a misuse, as a 5-bet usually refers only to preflop). This term lacks broad consensus; use with caution.
This term is not a standard Texas Hold'em term. Generally, "5-Bet" refers to the fifth pre-flop bet, while the number of betting rounds on the river is usually described as "raise" or "re-raise", not "5-Bet". This combination may originate from a player's informal description of a specific hand scenario; due to the lack of authoritative definition and consensus, it is not recommended for use in serious strategy discussions.
