SB 200bb 3-Bet Jam
SB 200bb 3-Bet Jam
SB 200bb 3-Bet Jam An aggressive pre-flop strategy where the player in the small blind makes a third raise 3-bet and goes all-in directly, with an effective stack of 200 big blinds.
Meaning
SB 200bb 3-Bet Jam refers to a pre-flop situation where the small blind player, facing an open raise, chooses to re-raise all-in, with both players having effective stacks of about 200 big blinds (200bb). This is an ultra-aggressive 3-bet all-in strategy in extremely deep stack conditions.
Applicable Scenarios
- Against aggressive opponents: When facing a big blind or button player who frequently steals blinds, this can be used to counter their overly wide raising range.
- Range balancing: In deep stacks, pure value 3-Bet sizes are usually larger (e.g., 4-5x), while an all-in creates a polarized range (very strong hands or very weak bluffs).
- ICM or late tournament stages: However, it is more common in cash games because going all-in with 200bb depth carries extremely high risk and usually requires specific conditions.
Principles and Considerations
- Range construction: The all-in bet size eliminates post-flop play, so the opponent needs sufficiently strong hands to call. The SB player typically holds AA, KK, or a few bluff hands (e.g., A5s) for balance.
- Opponent's calling range: At 200bb depth, the opponent needs very strong hands (e.g., KK+, AKs) to call the all-in, so even if SB's hand is not the strongest, there is a high fold equity.
- Risk: If the opponent calls, SB may face huge variance and a significant loss of 200bb. Therefore, it is usually only used when the opponent's fold equity is high enough.
