Poker Term
UTG河牌圈四次加注彩虹牌面（UTG River 4-Bet Rainbow）
An uncommon compound term describing the action of a UTG under the gun player making a fourth bet on the river when the board is a rainbow three different suits.
Term Composition
- UTG (Under the Gun): The first position to the left of the big blind, acting first preflop.
- River: The final betting round in Texas Hold'em.
- 4-Bet: Usually refers to the fourth raise preflop (e.g., open raise → 3-bet → 4-bet). However, postflop, common terms for betting rounds are “bet”, “raise”, and “re-raise”; “4-bet” is rarely used.
- Rainbow: The flop or board consists of three cards of different suits, with no possible flush draw.
Term Usage
This combination is not a standard poker term and may originate from individual players' strategy discussions. A typical usage might refer to a UTG player choosing to make a fourth raise on the river against an opponent's multiple raises, with the river card creating a rainbow board (no flush possible). This scenario is extremely rare; in actual play, four raises on the river are uncommon, and the UTG position has limited actions on the river.
Notes
- This term lacks industry consensus and rarely appears in formal poker guides or strategy books.
- It is recommended to use clearer descriptions in communication, such as “UTG made a fourth raise on a rainbow river.”
- No related statistical data or examples of well-known players using this term.
