BB 100bb Steal

Overview

In No-Limit Hold'em cash games, a "BB 100bb Steal" refers to a situation where the big blind (BB) raises when all players have folded to them, leaving only the small blind (SB) to act. This occurs with effective stack sizes of 100 big blinds (bb), a common depth in online and live play. Unlike a traditional steal from the button or cutoff, the BB already has one big blind invested, so the raise is an attempt to win the pot immediately or isolate the SB.

Strategic Considerations

Rationale

Stealing from the BB can be profitable because the SB has a weaker range (having only posted the small blind) and may fold frequently to aggression. The BB's raise size is typically larger than a standard steal (e.g., 3-4bb) to compensate for the positional disadvantage and the SB's potential defense. With 100bb stacks, the BB can apply pressure without risking too much of their stack.

Range Construction

A balanced BB steal range includes strong hands (to value-bet) and some bluffs, given the SB's tendency to defend loosely. Example hands: high pairs, Ace-high, suited connectors. However, the BB must be cautious: the SB might 3-bet or call with a wide range, leading to difficult postflop situations out of position.

Adjustments

• SB Tendencies: If the SB folds often, the BB can steal with a wider range. Against a calling station, the BB should tighten up.
• Stack Depth: At 100bb, postflop play is manageable. Deeper stacks (200bb+) make stealing riskier due to implied odds.
• Game Flow: In aggressive games, frequent steals may be met with 3-bets, requiring the BB to have a defense strategy.

Comparison with Standard Steals

Traditional steals (from late positions) aim to collect the blinds without a fight. The BB steal differs:

• Already has one bb invested, so the risk-reward ratio is different.
• Position is worse (acting first postflop), so the BB must be selective.
• The SB's defending range is often capped (since they didn't open-raise), making postflop exploitation possible.

Example Scenario

Effective stacks: 100bb. Folded to SB who completes (or folds, but typically SB limps or folds). BB raises to 4bb with a hand like A♠5♠. SB folds. This is a successful BB steal.

Risks

• If the SB 3-bets, the BB must either fold (losing the one bb invested) or 4-bet (risking more).
• Out of position postflop, even with a range advantage, the BB can be exploited.

Conclusion

BB 100bb Steal is a nuanced play requiring careful stack and opponent consideration. It can be a profitable addition to a balanced game, but overuse leads to exploitation.
