SB 50bb Push Fold
SB 50bb Push Fold
A simplified strategy where the small blind with 50 big blinds effective stack chooses only to go all-in or fold, typically used as an exploitative approach against a big blind who folds too often or in certain heads-up scenarios.
Overview
"SB 50bb Push Fold" refers to a poker strategy where the small blind (SB) with an effective stack of 50 big blinds (bb) decides to either push all-in or fold, omitting any other actions like raising or calling. This approach is highly unusual because push/fold strategies are generally reserved for short stacks (under 15bb) where post-flop play is limited. At 50bb, standard play involves raising smaller amounts and playing post-flop. However, in specific exploitative situations—such as against an overly passive big blind (BB) who folds too often to shoves—the SB can profitably adopt an all-in-or-fold strategy.
When Is It Used?
This strategy is not part of GTO (Game Theory Optimal) play. Instead, it exploits a BB who over-folds to shoves. For example, if the BB folds more than 60–70% of the time to a push, the SB can profitably shove a wide range, even with 50bb, because the fold equity compensates for the risk. It might also appear in heads-up play where one player is significantly weaker and the opponent simplifies decisions. Additionally, some training tools or charts present a "push/fold" range for deeper stacks as a starting point for beginners, but this is not recommended for serious play.
Example Scenario
Assume heads-up blinds 50/100, SB has 5,000 chips (50bb), BB covers. SB decides to use push/fold only. If BB folds to shoves 70% of the time, SB can push any two cards profitably. The EV calculation: shoving 72o (which has ~33% equity when called) yields 0.7*(100+50) + 0.3*(0.335000 - 0.675000) = 105 - 51 = +54 chips per hand. This demonstrates the extreme exploitative nature.
Limitations
At 50bb, a push/fold strategy is suboptimal against competent opponents. The BB can adjust by calling wider, which destroys the SB's profitability. Moreover, post-flop play with 50bb is deep enough to use raises, 3-bets, and flop play, which are more effective and lower variance. Thus, "SB 50bb Push Fold" is a niche exploit, not a standard line.
Conclusion
While the term exists in poker literature as an example of extreme exploitation, it is not recommended for regular use. Most players should employ balanced raise-fold strategies at 50bb. Understanding this concept helps illustrate fold equity and stack depth dynamics, but it should be applied cautiously and only against clear over-fold tendencies.
