Poker Term
UTG+1 河牌彩虹面开池（UTG+1 River Open Rainbow）
In Texas Hold'em, it refers to the player in the UTG+1 position who bets first on the river, and the community cards are a rainbow all three different suits.
Term Composition
- UTG+1: Under the Gun +1, the position after the gun (first position left of the big blind), an early position. This position has a narrow range, suitable for entering pots with strong hands.
- River: The river betting round, after the fifth community card is dealt.
- Open: Refers to the first bet on a street (usually preflop, but here refers to the first bet on the river).
- Rainbow: A rainbow board, where the community cards have three (or more) different suits, usually meaning a flush draw is impossible.
Strategy Implications
On the river, when the UTG+1 player chooses to open (first bet) and the board is rainbow, it usually represents that they hold a strong made hand (such as top pair, two pair or better), because they are from an early position and the rainbow board eliminates flush draw possibilities, making it easier for opponents to judge.
Common Scenarios
- Flop is rainbow, turn and river do not change suits, the river card completes a possible straight. The UTG+1 player bets, trying to extract value from opponents who missed their straight draw.
- As a bluff, UTG+1 may exploit the lack of flush on the river rainbow board to represent holding a nut hand (such as a straight or three of a kind), forcing opponents to fold.
Notes
In practice, this term is not a standard vocabulary but a descriptive expression for a specific situation. Players more commonly use natural language like 'UTG+1 river bet on rainbow board'.
