枪口位河牌三枪（彩虹面）（UTG River Triple Barrel Rainbow）

Terminology Breakdown

• UTG: Under the Gun, the first action position to the left of the big blind, the earliest position.
• Triple Barrel: Three barrels, meaning consecutive bets or raises on the flop, turn, and river.
• River: The river, the betting round after the last community card is dealt.
• Rainbow: Rainbow board, referring to a flop with three cards of different suits, meaning no flush draw possible.

Meaning and Usage

This term describes a specific aggressive play: after open-raising from UTG, the player bets on the flop, turn, and river, and the flop is a rainbow board (reducing the possibility of flush draws). It usually represents a strong hand (such as top pair or better), or a bluff telling a consistent story. Since the UTG range is tight, and the rainbow flop reduces drawing possibilities, the Triple Barrel puts more pressure on opponents to fold. This play is common in deep stack situations and when the preflop raise is large.

Strategy Tips

• As the bettor: After a preflop raise, it's suitable to continuation bet on a rainbow flop, bet the turn, and bet the river to show an extremely strong range.
• As the defender: Consider the opponent's tight UTG range; a Triple Barrel often represents value hands or strong draws (but the rainbow board reduces draws), so usually you need a strong hand to call the river.
