HJ位河牌过牌-弃牌（彩虹面）（HJ River Check-Fold Rainbow）

Term Composition

• HJ: Abbreviation for Hijack, referring to the position under the gun plus one (typically UTG+1 at a six-handed table or UTG+2 at a nine-handed table).
• River: The river betting round, i.e., the betting round after the fifth community card is dealt.
• Check-Fold: Checking then folding, meaning the player checks first and folds if the opponent bets.
• Rainbow: Rainbow board, usually referring to a flop where all three cards are of different suits, but here it means that after the river, all community cards are of different suits (i.e., no flush draw possible).

Strategy Implications

This term describes a specific play: the player in the HJ position, on the river, with a rainbow board (no flush possible) and weak hand strength (e.g., only one pair or worse), chooses to check and prepares to fold in response to an opponent's bet. This strategy is often used in the following scenarios:

• The hand lost its value after continued betting on the flop and turn.
• The opponent's range contains many value hands with a relatively low bluffing frequency.
• The rainbow board reduces the opponent's bluffing opportunities from flush draws, making a fold more reasonable.

Notes

• This term is not a fixed strategy; it must be adjusted dynamically based on stack depth, opponent tendencies, and previous hand history.
• On a rainbow board, a player may be more inclined to make hero calls or value bets with medium-strength hands; check-fold is typically only suitable for weak hands.
• The "Rainbow" in the term emphasizes the lack of flush potential, simplifying the opponent's range assessment.
