Small Blind Continuation Bet Range

Overview

A continuation bet (c-bet) is a bet made by the preflop aggressor on the flop. The small blind continuation bet range refers to the specific range of hands the small blind (SB) uses to c-bet after raising from the SB and being called, usually by the big blind (BB) or a late-position caller. Since the SB is out of position postflop, range construction differs from in-position c-bets.

Key Considerations

Position Disadvantage

The SB acts first on every street after the flop, making c-betting riskier. The SB must balance value, protection, and bluffs while accounting for the opponent's ability to float or raise. A polarized range (strong hands vs. weak draws) is common.

Range and Board Texture

• Dry boards (e.g., K-7-2 rainbow): SB can c-bet a high frequency (70-80%) with many hands, including weak pairs and backdoor draws, because the opponent is unlikely to have hit.
• Wet boards (e.g., 9-8-6 two-tone): C-bet frequency drops to 40-50% because the opponent has more equity and can raise. The SB tends to c-bet with strong hands, combo draws, and sometimes nut draws; checks weak pairs and air.

Typical SB C-Bet Range

Assuming a standard SB opening range of about 40-50% of hands (e.g., 22+, A2s+, K9s+, Q9s+, J8s+, T8s+, 98s, 87s, 76s, 65s, 54s, ATo+, KJo+, QJo), the SB's c-bet range on a dry flop like K-7-2 might include:

• Value: Top pair or better (Kx, 77, 22), plus some medium overpairs (QQ, JJ).
• Bluffs: Hands with backdoor draws (e.g., A♠4♠, 6♦5♦) and low pairs that may fold to a raise (e.g., 33, 44).

On a wet flop like 9-8-6, the c-bet range tightens:

• Value: Sets, two pairs, overpairs (JJ+), top pair with good kicker (A9, K9).
• Draws: Open-ended straight draws (T7s, 75s), flush draws (A♠X♠), combo draws (J♠T♠).
• Check: Weak pairs (22-55), marginal top pairs (Q9), and complete air.

Adjustments vs. Opponents

• vs. Tight opponents: Increase c-bet frequency, especially on dry boards, as they fold too much.
• vs. Aggressive opponents: C-bet less often with weak hands, as they may check-raise frequently. Use a check-call or check-raise strategy with strong hands.
• vs. Calling stations: C-bet for thin value with hands like second pair, but avoid bluffing because they call too much.

GTO Considerations

Game Theory Optimal (GTO) play requires a balanced SB c-bet range. On dry boards, a 75% c-bet frequency is common, with a 2:1 ratio of value to bluffs. On wet boards, frequency drops to 60% with more draws in the betting range. Solver studies show that the SB should check more often with weak hands and some medium-strength hands to avoid being exploited.

Example

Example for illustration: SB opens A♦5♦ and BB calls. Flop is K♥7♠2♣. Even though A♦5♦ has no pair, it has a backdoor flush draw and an overcard. SB often c-bets ⅔ pot as a semi-bluff. If flop is 9♠8♠6♣, SB might check A♦5♦ because it lacks equity and is dominated by draws.

Conclusion

The small blind continuation bet range is a dynamic concept influenced by position, board texture, and opponent tendencies. Mastering it requires understanding value, bluff ratios, and when to deviate from standard frequencies.
