小盲位翻牌前彩虹挤压（SB Preflop Squeeze Rainbow）

Overview

"SB Preflop Squeeze Rainbow" is a non-standard but occasionally discussed term in poker strategy, combining the concepts of a preflop squeeze and a rainbow flop. This strategy emphasizes the small blind (SB) applying pressure with a squeeze preflop and planning to continue aggression on a rainbow flop, since the rainbow texture reduces opponents' flush draw possibilities, thereby lowering their equity when calling.

Strategic Rationale

• Preflop Squeeze: When one player raises and another calls, the small blind re-raises (squeezes) to force the original raiser and caller to fold, winning the pot immediately.
• Rainbow Flop: A flop with three cards of different suits, known as a "rainbow" board. On such a flop, no player can have a flush draw, making bluffs more effective since opponents are more likely to hold weak hands without draws.
• Combination: After a preflop squeeze from the small blind, a rainbow flop increases the bluffing efficiency of a continuation bet (C-bet) because opponents' drawing ranges are limited.

Execution Key Points

• Position: The small blind is out of position postflop, so the squeeze should be made with strong hands or hands with postflop playability (e.g., suited connectors).
• Size: The squeeze raise is typically 3-4 times the original raise plus one call unit. For example, if the original raise is 3BB and there is one call, the pot is 7.5BB; squeeze to 12-15BB.
• Example: CO opens to 3BB, BTN calls. SB holds 9♠8♠ and squeezes to 12BB. If the flop comes K♦7♣2♥ (rainbow), SB can bet about 2/3 pot, representing a strong hand like AK or top pair.

Considerations

• A rainbow flop is not completely safe; straight draws remain possible, so evaluate opponent ranges accordingly.
• This strategy relies on opponents' fold tendencies. It is riskier against calling stations or aggressive players.
• "Rainbow" in this context is non-standard terminology, often used in educational material or specific scenarios as shorthand.
