BB 40bb Push Fold

Definition

BB 40bb Push Fold is a simplified poker strategy used by the big blind (BB) when effective stacks are exactly 40 big blinds (bb). Under this approach, the BB only considers two actions against an open raise: moving all-in (push) or folding, disregarding calls, standard 3-bets, or other options. It is not considered theoretically optimal at this stack depth, but is sometimes employed as a learning tool or in specific tournament scenarios where opponents are weak or ranges are narrow.

Usage Context

While push/fold charts are most commonly associated with short stacks (under 20bb), the BB 40bb Push Fold strategy appears in some training materials for deeper stacks. The idea is that at 40bb, the BB can still apply significant pressure by shoving, especially against a small raise (e.g., 2x or 2.5x). The strategy assumes that calling or making a standard 3-bet is too complex or unnecessary, so the player reduces the decision to a binary choice based on hand strength. However, this simplification often leads to suboptimal play, as folding too many hands or pushing too wide can be exploited.

Considerations

• Hand selection: In a typical BB 40bb Push Fold range, the BB pushes with strong hands (e.g., high pairs, A-K, A-Q) and folds weaker ones. Some charts may include medium-strength hands depending on the opponent's raise size and tendencies.
• Opponent tendencies: The strategy performs better against tight players who open wide but fold to shoves, and worse against loose callers or those who 4-bet light.
• ICM and tournament stage: In tournaments, ICM considerations can make 40bb shoves risky, especially near the money bubble or at final tables. The strategy is more common in deep-stacked cash games or early tournament levels where chip values are linear.
• Alternatives: Standard 40bb strategy involves a mix of calling, 3-betting to a normal size (e.g., 3x), and occasional shoves. The push/fold simplification ignores these options, potentially sacrificing value and bluffing opportunities.

Example Scenario

In a cash game, the button opens to 2.5bb with effective stacks at 40bb. The BB using this strategy looks at their hand: if it is in the push range (e.g., A-J+, 77+, K-Q), they shove; otherwise, they fold. They never call or make a small 3-bet. While easy to implement, this approach may miss profitable calls with suited connectors or small pairs that play well deep.

Conclusion

BB 40bb Push Fold is a niche simplification for deep-stack play, useful for beginners learning range pressure but not recommended for advanced players seeking optimal strategies. At 40bb, a more nuanced approach that includes calls and standard raises usually yields better results.
