小盲河牌彩虹跟注（SB River Peel Rainbow）

Etymology and Scenario

"SB" stands for Small Blind, "River" refers to the fifth community card, "Peel" in poker often means calling to see the next card, here extended to a calling action on the river, and "Rainbow" describes a board where all cards are of different suits (no flush possible). This combination of terms describes a specific scenario: a player in the Small Blind, on the river, sees a rainbow board (e.g., ♠K♥Q♦9♣5♠2), and when an opponent bets, the Small Blind chooses to call.

Strategic Considerations

• Significance of Rainbow Board: Since no flush is possible, the opponent's bet usually represents made hands (such as top pair, two pair, straights) or bluffs, rather than draws. When calling, the Small Blind must evaluate their hand's connection to the board and typically holds medium-strength made hands or bluff-catching hands.
• Positional Disadvantage: The Small Blind is at a positional disadvantage on the river (if the opponent is in position), needing to act first after calling. Thus, the "Peel" may have a probing nature, especially when pot odds are favorable.
• Typical Example: The Small Blind holds A♦10♥, the river board is K♠Q♣9♦5♠2♠, and the opponent bets half the pot. The Small Blind calls, intending to catch a bluff or show down stronger than weaker made hands.
