Big Blind Stealing Range

Overview

In poker, particularly in no-limit hold'em cash games and tournaments, the big blind stealing range refers to the set of hands a player selects to open-raise from late position (usually the button or small blind) when everyone else has folded. The primary goal is to exploit the big blind's disadvantage by putting them in a difficult spot: they must either defend with a weak hand out of position or fold and give up their blind. A well-constructed stealing range is wider than a standard raising range, including many marginal hands that would not normally be played in earlier positions.

Key Considerations

Position and Table Dynamics

• The button is the most profitable position to steal from, as it has position on both blinds. The small blind can also steal but must act first post-flop.
• The tighter the big blind's defense range, the wider the stealing range can be. If the big blind folds too often, almost any two cards become profitable to steal.

Stack Sizes

• In tournament poker, ICM considerations and stack sizes affect stealing ranges. Short stacks (under 20 big blinds) often use push/fold strategies; medium stacks (20-40 bb) may raise to 2-2.5 bb; deep stacks allow for more speculative steals.
• A standard steal size is 2.5 big blinds from the button and 3 big blinds from the small blind, though adjustments are common.

Opponent Tendencies

• Against a passive big blind who rarely 3-bets or defends, the stealing range can be extremely wide (e.g., 50-60% of hands).
• Against an aggressive big blind who 3-bets frequently, the stealing range should be tighter and stronger, and may include traps like limp-re-raising.

Typical Stealing Range Example

A typical button stealing range against a standard opponent might include:

• All pairs (22+)
• All suited aces (A2s+)
• Offsuit aces above a threshold (e.g., A9o+)
• All suited broadways (KTs+, QTs+, JTs+)
• Some offsuit broadways (KJo+, QJo)
• Suited connectors and one-gappers (45s+ to T9s, 57s+, etc.) This represents approximately 40-50% of all hands. The exact range varies based on the factors above.

Adjusting the Range

• When the big blind folds too much: Add more marginal hands, such as low suited connectors, weak aces, and even pure bluffs like 72o.
• When the big blind defends widely: Tighten up and only raise hands that play well post-flop with position, favoring high-card strength and suitedness.
• Against frequent 3-bettors: Either tighten the stealing range to hands that can call a 3-bet (e.g., pairs, suited aces, strong broadways) or incorporate a 4-bet bluff range with hands like A5s or low suited connectors.

Relationship to Blind Defense

Stealing and defense are two sides of the same coin. The big blind must have a balanced defense range to prevent the button from profitably stealing any two cards. A standard defense range might include calling with suited connectors, pocket pairs, and strong aces, and 3-betting with premium hands and some bluffs.

Conclusion

Mastering the big blind stealing range is crucial for a winning poker strategy. It requires constant adjustment based on opponent tendencies, stack sizes, and table dynamics. The most successful players exploit profitable stealing opportunities while avoiding spew against tough defenders.
