10bb Resteal

What Is a 10bb Resteal?

A 10bb resteal is a short-stack tournament strategy employed when a player's effective stack size is around 10 big blinds. The player, typically in the blinds or late position, re-raises (resteals) after an opponent has opened with a raise. The goal is to leverage the fold equity of a player who has invested only a small portion of their stack, forcing them to fold or risk a large portion of their chips.

Why 10 Big Blinds?

At 10bb, stacks are shallow enough that opponents cannot profitably call light, but deep enough that a re-raise (usually a shove) is large enough to threaten a significant portion of the original raiser's stack. The math works as follows: if the original raiser opens to 2.5bb, a 10bb resteal with a shove of 10bb means the raiser must call 7.5bb to win 13bb (including blinds), needing about 36% equity. Most standard opening ranges (e.g., 40% from the button) have many hands that do not meet this threshold, making the 10bb resteal highly profitable.

Strategic Considerations

• Position: The resteal is most effective from the blinds because it closes the action and puts maximum pressure on the opener. Also, openers in late position (cutoff, button) tend to have wider ranges, increasing fold equity.
• Stack Sizes: The restealer should have exactly 10-12bb; if too short (e.g., 6bb), the re-raise may be too small to force folds; if too deep (e.g., 15bb), the threat is less immediate. The original raiser's stack must also be significant (e.g., 20-30bb) so they feel pressure.
• Range: Typical 10bb resteal hands include pocket pairs (22-77), suited aces (A2s-A9s), broadways (KQ, QJ), and some suited connectors (T9s, 98s). These hands have good equity when called but also rely heavily on folds.
• ICM: In tournaments nearing the money or bubble, ICM considerations alter math. Surviving players may be more risk-averse, increasing fold equity, but the restealer must also avoid busting on the bubble.

Example Scenario

Blinds 500/1000, antes 100 Hero is in the big blind with 10,000 chips (10bb). Action folds to the button (30,000 chips) who raises to 2,500. Hero looks down at A♠5♠. This is a prime 10bb resteal spot: Hero shoves all-in for 10,000. The button must call 7,500 to win 13,000, needing ~36% equity. If the button opens 40% range, many of those hands (like weak aces, suited connectors) may fold. The play is profitable if the button folds often enough, even when called Hero has roughly 30-40% equity.

Conclusion

The 10bb resteal is a fundamental short-stack weapon in no-limit hold'em tournaments. It exploits wide ranges and medium stacks, converting fold equity into chips. Success depends on reading opponent tendencies, stack dynamics, and tournament payouts.
