HJ 100bb 3-Bet Jam

HJ 100bb 3-Bet Jam

Terminology Explanation

HJ (Hijack) is the position after the under-the-gun and before the cutoff in a full-ring game. 100bb indicates effective stack depth of approximately 100 big blinds. 3-Bet Jam refers to making a third raise pre-flop (i.e., a 3-Bet) and going all-in directly, instead of making a standard-sized 3-Bet.

Strategic Background

This play is common in deep-stack or medium-stack cash games or tournaments, often used as part of a mixed strategy. When the HJ player believes the opponent's opening range is wide and the opponent will call or 4-bet too often against a standard 3-Bet, going all-in directly can put extreme pressure on the opponent, forcing them to fold many medium-strength hands and win the pot immediately.

Applicable Conditions

• The opponent's opening range is wide and their fold rate to an all-in is high enough.
• The player's own hand range has good blocking effects, e.g., holding an A or K provides good blockers.
• Effective stack of about 100bb, where the pot odds offered to the opponent by an all-in are not favorable, effectively forcing most hands to fold.
• Avoid being exploited by opponents; balance your range by sometimes doing this with strong hands (like AA, KK) for value.

Risks and Cautions

• If the opponent is a calling station type or holds strong hands (like TT+, AK, etc.), the 3-Bet Jam may be called and face significant variance.
• At 100bb depth, going all-in is usually not optimal because a standard 3-Bet size (e.g., 2.5-3x the raise) leaves more room for maneuver and avoids unnecessary risk. Therefore, this play is more of an exploitative strategy based on specific reads.
• Long-term use of this strategy may lead to range imbalance and be exploited by experienced opponents.
