What is a Blind Steal?

Blind stealing (Steal the Blinds) refers to when, in Texas Hold'em pre-flop, after all players before you have folded, the button (or an earlier position) makes a raise intending to take down the blinds directly. Since the button has absolute position advantage post-flop, and the blinds' ranges are typically wide but with varying defense willingness, blind stealing becomes an important source of profit.

Why is Blind Stealing Profitable?

• Dead Money Effect: The blinds are already dead money in the pot; successfully stealing yields risk-free profit.
• Position Advantage: The button controls the pot post-flop, making it easier to realize hand equity.
• Fold Equity: Most players defend their blinds with tighter ranges, especially the small blind.

Basic Math of Blind Stealing

Assume the small blind is 0.5 BB, the big blind is 1 BB, with 1.5 BB in dead money. You raise to 2.5 BB. Opponents need to defend below a certain frequency for the steal to be directly profitable. Calculate required fold equity:

• Risk: 2.5 BB
• Reward: 1.5 BB
• Required fold equity = Risk / (Risk + Reward) = 2.5 / (2.5 + 1.5) = 62.5%

That is, if both blinds fold more than 62.5% combined, any two cards can be profitably stolen. In practice, considering re-steals and post-flop play, such extremes are not always necessary.

Building a Button Steal Range

Base Range (vs. blinds with ~60-70% average fold equity)

• Value Opens: Top 15-20% of hands, such as all pairs, Ax, KQo+, suited connectors.
• Steal Range: Expand to about 40-50% of hands, including:
  • All pairs (22+)
  • All Ax (A2o+)
  • K2s+, Q2s+, J2s+ (suited potential)
  • Some offsuit connectors (T9o+)
  • Some offsuit gappers (QTo, JTo)
  • All suited connectors (54s+)
  • All suited gappers (97s+)

Example: Typical button steal range (~40% of hands)

Adjustment Factors

1. Blinds' Fold Equity

• High Fold Equity (>70%): Expand to 50-60% of hands, even any two cards (but avoid being predictable).
• Low Fold Equity (<50%): Tighten range, only top 25-30% value hands, cut marginal ones.

2. Stack Depth

• Shallow Stacks (<20 BB): Use wide range for all-in or raise, but beware of ICM pressure.
• Deep Stacks (>100 BB): Can be more aggressive, but consider the threat of re-steals; increase value hands proportion.

3. Player Types

• Tight-Passive: Steal frequently, almost any two cards.
• Loose-Aggressive: Reduce steals, only quality hands, as opponents will often 3-bet or fight back.
• Calling Station: Reduce steals, use more value hands, as opponents call a lot; play well post-flop.

Balancing Stealing and Re-stealing

To avoid being exploited by targeted 3-bets, balance your opening range:

• Value Opens: Strong hands (TT+, AJs+, AQo+) to continue against 3-bets.
• Steal Range: Weak hands (e.g., J8s, Q7s) to raise, but mostly fold to 3-bets.
• Mixed Strategy: Include some medium-strength hands in your steal range (e.g., A9o, KTo) to call 3-bets or 4-bet, avoiding exploitation.

Example balance:

• Open 40% of hands, with 60% weak (fold to 3-bet) and 40% strong/medium (defend against 3-bet).

Post-flop Play Tips

• Heads-up Flop: C-bet frequency around 60-70%, leveraging position to take down pots.
• Flop: Small bets on dry boards; check to control pot on wet boards.
• Turn and River: Adjust based on opponent's range, often aiming for showdown value.

Common Mistakes

• Stealing too frequently without considering opponents' fold equity.
• Automatic c-bets post-flop, ignoring board dynamics.
• No defense range against 3-bets, leading to repeated exploitation.
• Over-aggressive re-stealing from the small blind.

Summary

Button steal is a key profit strategy, but it requires dynamic adjustments based on opponents, stack depth, and your own range. The core is to calculate the required fold equity, select suitable hands based on opponent tendencies, and balance the defense range to avoid being exploited.
