SB 10bb Steal

Definition

SB 10bb Steal refers to a specific short-stack strategy in No-Limit Hold'em (NLHE), commonly used in tournaments or cash games with antes. When the effective stack size in the Small Blind (SB) is approximately 10 big blinds (bb), the SB opens (typically by pushing all-in) to steal the Big Blind (BB) and any antes, exploiting the fact that the BB must fold a significant portion of their range to remain profitable against the SB's shove.

Context and Usage

This play is a subset of the broader "push/fold" strategy, which becomes optimal when stacks shrink to around 10-15 bb. At 10 bb, the SB is too short to make standard raises (e.g., 2-2.5x) without committing a large fraction of their stack; thus, a shove is the only viable bet size that preserves fold equity. The SB's goal is to win the uncontested blinds and antes (the "dead money") without a showdown. If called, the SB's hand typically has decent equity against the BB's calling range, but the primary value comes from folds.

The effectiveness of an SB 10bb steal depends heavily on the BB's assumed calling range. In equilibrium (GTO), the BB should call with roughly the top 30-40% of hands when facing a 10bb shove from the SB, but in practice, many opponents deviate, calling too tight or too loose. Consequently, the SB can adjust their shoving range accordingly.

Range and Considerations

A balanced SB 10bb shoving range at equilibrium includes approximately top 50-60% of hands (e.g., any pair, any ace, any king, suited connectors, and some offsuit broadways). However, exploitative adjustments are common:

• Against a tight BB (folds >70%): The SB can profitably shove any two cards (ATC), as the high fold equity compensates for the occasional bad call.
• Against a loose BB (calls >50%): The SB should tighten to hands with at least 40-50% equity, such as Ax, Kx, pairs, and suited connectors.

Positional awareness is crucial. Since the SB acts first post-flop but is all-in, their hand must be strong enough to win when called. Suitedness and connectedness matter less at 10bb because post-flop play is nonexistent; raw equity vs. the BB's calling range is the main factor.

Risks and Adjustments

The primary risk of an SB 10bb steal is being called by a dominated hand or a better ace, leading to elimination or significant chip loss. Additionally, if the BB is aware of the SB's wide range, they may call lighter, reducing the steal's profitability. To counter this, the SB should occasionally limp or make a smaller raise (e.g., 2.2x) with strong hands, though this is rare at 10bb due to awkward stack-to-pot ratios.

Another risk is the presence of antes. With antes, the pot is larger preflop, making steals more profitable but also giving the BB better odds to call. The SB should adjust by shoving slightly tighter (roughly 5% fewer hands) when antes are large.
