CO 150bb Resteal
CO 150bb Resteal
A 3-bet re-raise made from the cutoff position against a late-position open-raise (typically from the hijack or button) when effective stacks are 150 big blinds, designed to exploit the opener's wide stealing range and build a large pot with positional advantage.
Overview
CO 150bb Resteal refers to a specific poker strategy where a player in the cutoff (CO) position re-raises (3-bets) an opponent who opened from a later position—usually the hijack (HJ) or button (BU)—when both players have deep stacks of approximately 150 big blinds (bb). This move is a variation of the classic resteal, which typically occurs from the blinds against a late-position raiser. At 150bb, the dynamics change significantly: deeper stacks allow for more post-flop maneuverability but also increase the risk of committing chips with marginal holdings.
Strategic Context
In standard poker, a steal is an open-raise from a late position (CO, BU, or SB) intended to take down the blinds uncontested. A resteal is a 3-bet by a player who suspects the original raiser is stealing. When the restealer is in the CO, the situation is less common because the CO acts before the BU. However, if the HJ opens (a position also considered a stealing position in many lineups), the CO can resteal with a polarized range—strong value hands and some bluffs—to punish the HJ's wide opening range. At 150bb, the effective stack depth means that 3-bets and subsequent 4-bets can become substantial, requiring careful hand selection and post-flop planning.
Key Considerations
- Position: The CO has positional advantage over the HJ but not over the BU. If the BU opens, the CO cannot resteal because the CO has already folded. Therefore, CO 150bb Resteal typically applies when the HJ opens or, in some aggressive games, when the BU opens from an earlier position (though this is rare).
- Stack Depth: At 150bb, 3-bet sizing is usually around 8-10bb. The restealer must be prepared to face a 4-bet or a call. Deep stacks allow for more bluffing opportunities but also mean that opponents may call with suited connectors or small pairs, aiming to win a large pot.
- Range Construction: A typical CO restealing range against a HJ open at 150bb might include premium hands (QQ+, AK) for value and suited aces (A5s, A4s) or suited connectors (KQs, QJs) as bluffs. The exact mix depends on the opponent's tendencies.
- Exploitation: This play is most effective against aggressive players who open too wide from the HJ. Against tight players who only raise strong hands, restealing becomes less profitable.
Example Scenario
Hero is in the CO with 150bb. Villain in the HJ (also 150bb) opens to 3bb. Hero 3-bets to 9bb with A♠5♠. Villain folds. This is a standard resteal with a suited ace, using its blockers to reduce the likelihood of Villain holding AA or AK. If Villain calls, Hero will have positional advantage and a hand that can flop strong draws.
Risks and Adjustments
A CO 150bb Resteal is not mandatory and should be balanced with a strong value range. Overusing it can lead to being exploited by observant opponents who will adjust by 4-betting light or calling wider. Additionally, deep stacks mean that even a modest 3-bet can create a large pot, so poor post-flop play can be costly.
