UTG 100bb Open Jam

Overview

UTG 100bb Open Jam is a high-risk poker strategy, typically seen in tournament mid-stages or cash games. When holding around 100 big blinds (bb) from under the gun, a player chooses to open-shove instead of making a standard raise or call. This play aims to exert maximum pressure with deep stacks, forcing opponents to fold marginal hands while avoiding complex post-flop decisions.

Use Scenarios

• Late tournament stages: When blind levels are high and opponents are tight-passive, an Open Jam can steal blinds and antes, accumulating chips.
• Against aggressive players: If players in later positions frequently 3-bet, Open Jamming can prevent exploitative raises.
• Short or medium stacks: 100bb is a medium depth; shoving can avoid being forced into a passive position after a re-raise.

Strategic Considerations

• Hand range: Usually strong hands (e.g., TT+, AQ+) or some mixed hands (e.g., small pairs, suited connectors) to balance the range. The specific range should be adjusted based on opponent tendencies.
• Position disadvantage: UTG is the worst position, with several players yet to act behind, making a shove vulnerable to calls or re-shoves. Therefore, hand selection must be careful.
• Opponent calling range: Opponents may call with strong hands like TT+, AQ+, or a wider range (e.g., against tight players).

Pros and Cons

• Pros: Simplifies decisions, avoids post-flop mistakes; applies pressure on tight players; can build a loose-aggressive image.
• Cons: Loses value because strong hands may not get paid off; when called, the shover is usually behind, and with deep stacks the loss is significant.

Variations

• Different stack depths: For stacks larger than 100bb, Open Jam efficiency decreases as opponents' calling ranges widen; for stacks below 50bb, it becomes more common.
• Other positions: Open Jams from middle or late positions can have wider ranges, but UTG, being the worst position, typically has the tightest range.
