Small Blind Balance Strategy: Range Construction for Attack and Defense
11 views
The small blind is one of the most difficult positions preflop. This article from a practical perspective explains how to build a balanced attack and defense range: including value 3-bets, bluff 3-bets, flat calls and other hand types, and elaborates on construction logic, adjustment factors, and GTO references, helping you avoid being exploited by the big blind and improve long-term profitability.
Position Scenario Explanation
The small blind (SB) is the trickiest preflop position for three reasons:
- Position Disadvantage: Always acts first postflop, with the least information.
- [Pot Odds] Discount: Only need to invest half a bet to enter the pot, causing the big blind's defense range to widen.
- Blind Stealing Opportunity: If the big blind folds too often, SB can profit by raising with a wider range.
Therefore, SB's strategy needs to find a balance between protecting their own blind and attacking the opponent's blind. A solid SB range should include: value hands (strong hands), bluff hands (for balance), and some flatting hands.
Recommended Range (Text Description)
The following is a typical 6-handed preflop SB range (assuming 100BB effective stacks, no limpers):
[3-bet] / Raise Range (approx. 20-25% of hands)
- Value [3-bet]: [TT]+, AQ+, [KQs] – These hands have a clear advantage against CO/BU raises.
- Bluff 3-[bet]: [A5s]-[A2s], [KTs], [QJs], [JTs], small pairs ([55]-[66]), and other hands with backdoor draws or blockers.
- [Calling Range] (Flatting): It is generally recommended not to flat too often to avoid being exploited. Consider: [22]-[99] (some), [ATs], KJ, QJ, some suited connectors (e.g., [T9s]-[76s]).
Note: When facing an [UTG] raise, the [3-bet range] should be tighter (about 12-15%), and the flatting range narrower.
