Complete Guide to Stealing Blinds from the Button: Practical Strategy from Frequency to Range

Why Stealing Blinds from the Button Is So Important

The [button] (BTN) is the last to act preflop, offering a positional advantage. Blind stealing refers to raising from the button or later positions when it folds to you, aiming to take the blinds' pot uncontested. Successful stealing not only wins the blinds without competition but also allows you to apply pressure on later streets using position.

Profit from blind stealing comes from two sources:

• Direct pot: The sum of the small and big blinds (usually 1.5 BB). Suppose your steal success rate is 60%, and you raise to 2.5 BB. Expected value: 60% × 1.5 BB - 40% × 2.5 BB = 0.9 BB - 1 BB = -0.1 BB, which seems negative? But don't forget postflop value. In reality, due to the blinds' weaker defending ranges and your positional advantage, it's positive EV in the long run.
• Exploitation: Many players either fold too much or defend too much from the blinds, allowing you to adjust accordingly.

The Mathematics of Blind Stealing

Steal success depends on the blinds' fold frequencies. Suppose the small blind folds 70% and the big blind folds 45%. The probability both fold = 0.7 × 0.45 = 31.5%. So you only take the pot directly about 30% of the time; the remaining 70% goes to a flop.

The EV formula for blind stealing is: EV = (fold equity) × (pot size) + (1 - fold equity) × (postflop EV) - (raise amount)

Simplified model: When you raise to 2.5 BB with a pot of 1.5 BB, you need the fold equity to be 2.5/(1.5+2.5) = 62.5% to break even on the immediate pot (ignoring postflop). But because you have position, you can make up some losses postflop, so the actual required fold equity is lower.

Typically, when the combined fold equity of the blinds exceeds 50%, stealing is automatically profitable. In cash games, many players fold too often from the blinds, so adjusting your stealing frequency is key to profit.

Building Your Button Stealing Range

Your stealing range should adjust dynamically based on opponents' defensive tendencies. Below is a baseline range against unknown opponents (average defense frequency) with 100 BB effective stacks.

Baseline Stealing Range (about 40% of hands)

• Strong hands (value raises): [88]+, [ATo]+, [A9s]+, [KJs]+, [QJs], [JTs], etc. — these are easy to play even postflop.
• Medium hands (semi-steals): [22]-[77], [A2s]-[A8s], [A2o]-[A9o], [K9s]+, [KTo]+, [QTo]+, [JTo], [T9s], [98s], [87s], etc.
• Marginal hands (steal inflation): [76s], [65s], [54s], [A2o], [K2s]-[K8s], [Q2s]-[Q9s], [J2s]-[J9s], [T2s]-[T8s], etc.

Adjustment Principles

• Opponent folds too much (blind fold equity > 60%): Expand range to over 50%, adding more junk like all suited connectors, all A-high, all K-high.
• Opponent defends too tightly (fold equity > 70%): You can steal with almost any two cards, but watch out for re-steals.
• Opponent 3-bets frequently: Tighten your stealing range, only raise strong hands (about 25%), and increase calling 3-bets or 4-betting frequency.
• Opponent calls passively: Use a wide raising range and apply pressure postflop with bets.

Choosing Your Raise Size

Standard steal raises are 2.5 BB or 3 BB. Key considerations:

• 100 BB deep stacks: 2.5 BB is more common, as it controls risk and offers poor pot odds to opponents.
• Shallow stacks (< 30 BB): You can raise to 2 BB or go all-in to steal.
• Opponent's calling tendency: If opponents call too much, increase raise size (e.g., 3.5 BB) to reduce their implied odds.
• Re-steal risk: Against frequent 3-bettors, a small raise (2 BB) can induce wide 3-bets, which you can then 4-bet as a counter.

Dealing with Re-steals (3-bets)

When you raise and face a 3-bet, your decision depends on opponent's 3-bet range.

• Opponent 3-bets tight (about 5%): Fold most of your stealing range, only call or 4-bet with super strong hands ([QQ]+, AK).
• Opponent 3-bets loose (> 10%): Increase 4-bet frequency, using blocker hands like [A5s], [KQo] as 4-bet bluffs. Against calling stations, go all-in for value with strong hands.

A typical 4-bet range might include [QQ]+, AK, and some [A5s], [KQo] etc. With 100 BB effective, 4-bet to 22-24 BB; if facing a 5-bet shove, call based on pot odds.

Postflop Stealing Strategy

If the steal fails (opponent calls), you have positional advantage postflop and can c-bet at a high frequency.

• Dry flops (e.g., K-7-2 rainbow): C-bet almost your entire range, as opponents often miss.
• Wet flops (e.g., 9-8-6 suited): Narrow your betting range; only continue with made hands and draws.
• Turn and river: Adjust based on opponent's range, using blockers and storylines for bluffs.

Common Mistakes and Adjustments

• Fixed stealing frequency: Adjust for each opponent; don't use one range for all.
• Constant raise size: Mix sizes against certain opponents.
• Ignoring the small blind: The small blind's defending range is usually tighter than the big blind's, but due to positional disadvantage they fold more often. Watch the small blind's 3-bet frequency and be more conservative when needed.
• Over-stealing leads to high 3-bet rate: If you get 3-bet frequently, tighten up immediately and be ready to 4-bet.

Summary

Stealing from the button is a core tool for profitability. Basic strategy: use a 40% range, raise to 2.5 BB, and adjust based on opponents. The key to successful blind stealing lies in observing opponents' fold and 3-bet tendencies, and flexibly adjusting your range. Remember, position is your greatest weapon—use it well.
