STRATEGY article: Hijack Steal and Blind Defense

Characteristics of the Hijack

The Hijack (HJ) is located after the Under the Gun (UTG) position and before the Cutoff (CO), in the middle-to-late position. In a 6-max game, the hijack acts third; in a 9-max game, it acts fourth. Because the Cutoff, Button, and blinds are still to act, the hijack must consider the ranges of subsequent players when attempting to steal.

However, the hijack still has value in stealing blinds: blind players often defend their blinds by calling or re-raising with wider ranges from unfavorable positions, and the hijack can profit by choosing the right timing and range, leveraging positional advantage.

1. Hijack Stealing Strategy

1.1. When to Steal

• Passive blind players: If the small and big blinds have high call rates, low 3-bet rates, and tend to fold postflop, stealing is more profitable.
• Tight-aggressive image: If you have recently shown down strong hands, you can widen your stealing range.
• Normal stack depth: Around 30-100 BB is optimal for stealing. With deep stacks (>150 BB), blinds are more likely to defend with suited connectors; with short stacks (<20 BB), stealing is risky and you should focus on shoving or folding.

1.2. Recommended Stealing Range (6-max Example)

The following ranges are typical and should be adjusted based on opponents:

• Linear range: About 22% of hands, including all pairs (22+), all Ax (A2s+, A9o+), suited connectors (56s+), some suited gappers (J9s+, T8s+), and hands like KQo, KJs.
• Polarized range: About 30% of hands, but includes more weak hands (e.g., small suited connectors, weak Ax) balanced with a few strong hands.

Beginners are advised to use a linear range to avoid complex postflop situations.

1.3. Opening Sizing

• Standard steal: 2.5-3 BB. If blinds are passive, you can use 2.2 BB to reduce cost.
• Against loose-aggressive blinds: Increase to 3.5-4 BB to force them to call with worse hands and reduce the frequency of suited connectors calling.

2. Blind Defense Strategy (3-betting vs Hijack Open)

3-betting from the blinds is the key defense against hijack steals. Its goal is to force the hijack to fold many medium-strength hands while value-raising with strong hands.

2.1. When to 3-bet

• High hijack steal frequency: If the opponent's opening rate from HJ is above the industry average (~25%), 3-betting is more profitable.
• Healthy stack: At least 30 BB to avoid being committed.
• One blind already folded: If only one blind remains, 3-betting has higher success (because the hijack must worry about both blinds).

2.2. 3-betting Range (Common for Both Blinds)

Divide the range into value and bluff parts:

• Value range: JJ+, AK (about 4% of hands). These hands have significant equity against the hijack's calling range.
• Bluff range: A2s-A9s, K9s-Q9s, suited connectors (e.g., 76s-98s), weak Axo (A2o-A8o), etc., but control frequency. Typically, the bluff-to-value ratio is about 1:1 or 1.2:1.

The small blind should 3-bet more conservatively due to poor postflop position; the big blind can be slightly wider because they already have 1 BB invested and better position than the small blind.

2.3. 3-bet Sizing and Responding to 4-bets

• 3-bet size: Usually 3-4x the hijack's open. For example, if HJ opens 3 BB, 3-bet to 9-12 BB. Too large a size forces opponents to call only with strong hands, reducing bluff profitability; too small gives good odds.
• Facing a 4-bet: Value hands should shove or call (depending on stack depth); bluff hands mostly fold. However, if the opponent 4-bets frequently, consider 5-bet shoving with some strong bluffs (e.g., A5s).

3. Hijack Adjustments When Facing a 3-bet

When the hijack encounters a 3-bet, they should fold most weak hands from their stealing range, such as small pairs, weak Ax, and suited connectors (unless specific reads). The calling range should include: TT+, AQ+, and some suited connectors (e.g., T9s, JTs). The 4-bet range: QQ+, AK, occasionally adding A5s for balance.

Summary

Hijack stealing is a fundamental part of blind battles but requires dynamic range and sizing adjustments. 3-betting is the core defensive weapon for the blinds, with frequency control being crucial. In the long run, balancing aggression and defense maximizes profit.
