100bb Push Fold

Definition

100bb Push Fold refers to a simplified decision-making framework in poker where a player restricts their options to either moving all-in (push) or folding, regardless of having a deep stack of 100 big blinds (100bb) or less. This strategy is an extension of classic push/fold charts, which usually apply to short stacks (under 20bb). In standard play, pushing at 100bb is rarely optimal because the player can raise smaller amounts, but the concept is used in specialized contexts such as extreme ICM pressure (e.g., on the bubble of a large field tournament) or when facing overly tight opponents who over-fold to large bets.

Background

Traditional push/fold strategies are grounded in Nash equilibrium for shallow stacks, where the risk of being outplayed post-flop is minimized, and fold equity is maximized. At deeper stacks like 100bb, more nuanced strategies involving raises, 3-bets, and post-flop play are generally superior. However, the term "100bb Push Fold" has emerged in advanced tournament training to illustrate that under certain conditions (e.g., large antes, high blinds relative to stack, weak opponents, or severe ICM implications), a simplified push/fold approach can be profitable even with a deeper stack. This is not a baseline strategy but a situational exploit.

Application

Typical scenarios where 100bb push/fold might be considered:

• Bubble or Final Table ICM: When the payout jumps are steep, players often fold hands they would normally play. Pushing with a wide range can pressure opponents into incorrect folds. For example, with 100bb on the bubble, a player might push with hands like small pairs or suited connectors if they believe opponents are folding too much.
• Ante Structure: In tournaments with large antes, the effective stack in terms of big blinds may be smaller; a 100bb stack with high antes can play like a shorter stack, making push/fold viable.
• Opponent Exploitation: Against opponents who call pushes too tightly (e.g., only with AA/KK), a player can profitably push a very wide range even with 100bb. Conversely, against calling stations, push/fold is less effective.
• Solvers and Training: Modern solvers sometimes output push/fold ranges for deep stacks in specific spots, especially when post-flop skill disparities exist or to simplify complex decisions.

Considerations

Using push/fold at 100bb carries significant risks:

• Loss of Post-Flop Edge: Pushing forfeits the opportunity to extract value from weaker hands or bluff efficiently.
• Variance: All-in for 100bb creates huge swings; bankroll management must account for this.
• Counter-Strategies: Skilled opponents may adapt by widening their calling ranges or 3-betting light, rendering the push/fold approach exploitable.

In summary, 100bb Push Fold is not a standard recommendation but a specialized, exploitative tool. It should only be deployed after careful assessment of opponents, tournament dynamics, and stack sizes. Most players are better suited to a balanced raising range at this depth.
