> Source: [Small Blind (SB) Poker Strategy: 3-Bet Or Fold Playbook & BvB Ranges on Smarter.Poker](https://smarter.poker/learn/positions/sb)

## Executive Summary
The Small Blind (SB) Posts 0.5 Big Blinds Before The Cards Are Dealt And Must Act First On Every Postflop Street. Because Playing Out Of Position Without The Initiative Is Expensive, Modern GTO Strategy Uses A Strict "3-Bet Or Fold" Approach From The Small Blind Against Open Raises.

## Quantitative Seat Metrics (100BB Baseline)
- **Position Code**: `SB` (Blinds)
- **GTO Raise First In (RFI) Frequency**: 41.0%
- **3-Bet Frequency**: 13.5%
- **Cold-Call Frequency**: 0.8%
- **Expected Winrate**: -14.5 BB/100

## Core Preflop & Postflop Strategy
Against Any Open Raise From UTG Through The Button, Eliminate Flat-Calling Almost Entirely In Raked Cash Games And Play A Linear 13.5% 3-Bet Range Sized At 3.5x To 4.0x The Open. When Folded To You In Blind-Vs-Blind (BvB), Raise 3.0x Or Mix Limps And Raises Across 41.0% Of Hands.

## Positional Realization & Postflop Advantage
While The Small Blind Suffers A Positional Disadvantage Postflop, Its 3-Bet Range Is Highly Concentrated With Broadway Cards And Overpairs, Allowing Aggressive Flop C-Betting And Turn Barreling In 3-Bet Pots.

## Common Population Leaks To Avoid
- Flat-Calling Open Raises From The Small Blind And Playing Multiway Pots Out Of Position After The Big Blind Squeezes Or Calls.
- Using Small 3x 3-Bet Sizings Out Of Position Instead Of Sizing Up To 3.5x To 4.0x To Deny In-Position Equity.
- Open-Limping Weak Uncoordinated Hands In Blind-Vs-Blind And Check-Folding To Every Big Blind Isolation Raise.
