枪口+1河牌圈彩虹面跟注（UTG+1 River Peel Rainbow）

Etymology and Breakdown

This term is a combination of three common poker concepts and is used infrequently, typically in advanced strategy discussions.

• UTG+1: A position term referring to the second seat to the left of the big blind, i.e., the seat after the UTG (under the gun). It is an early position, requiring tight hand selection.
• River: The betting round after the fifth community card is dealt, the final stage of a hand.
• Peel: Originally means calling on the flop to see the next card; by extension, it means calling on any street. Here, "River Peel" can be understood as calling on the river.
• Rainbow: Describes a flop or turn where all three community cards are of different suits, reducing the possibility of a flush draw.

Scenario and Strategy

A typical situation: A player enters the pot from UTG+1, and after action on the flop and turn, decides to call an opponent's bet on the river while the board remains a rainbow. In this scenario, the player usually holds a strong made hand (such as top pair or two pair), because the rainbow board eliminates flush draws, narrowing the opponent's value range. Additionally, due to the early position of UTG+1, the player's opening range is relatively tight, so a river call requires evaluating pot odds and opponent tendencies.

Notes

This term is not a standard poker term. In actual communication, it is better to express it in separate parts, for example: "I was in UTG+1, called on the river, and the board was a rainbow."
