HJ Heads-Up Pot Preflop Strategy

Overview

The hijack (HJ) is the position two seats to the right of the button. In heads-up pots preflop, the HJ is often the raiser facing only the big blind (or a single limper). The strategy focuses on opening ranges, responding to three-bets, and adjusting based on stack depths and opponent tendencies.

Opening Range

From HJ in a heads-up pot (e.g., everyone folds to HJ, and only the blinds remain), a typical opening range is wider than from early positions but tighter than from cutoff or button. A common range includes about 20-25% of hands: all pairs (22+), suited aces (A2s+), offsuit aces (ATo+), suited broadways (KQs, QJs, JTs, T9s), and some suited connectors like 98s, 87s. This range can be adjusted based on opponent's tendencies and stack sizes.

Adjustments by Stack Depth

• Deep stacks (100+ big blinds): Open slightly wider, especially with suited connectors and small pairs, to leverage implied odds. Be cautious with marginal hands against aggressive three-bettors.
• Short stacks (30-50 big blinds): Tighten opening range marginally. Prioritize hands that play well all-in (e.g., high pairs, strong aces). Avoid speculative hands that need deep stacks to realize equity.

Responding to Three-Bets

When facing a three-bet from the blinds, the HJ should defend a balanced range. With effective stacks around 100 big blinds, defend about 50-60% of your opening range. Continue with strong hands (pairs TT+, AQ+), some suited connectors that flop well (e.g., 98s), and fold marginal offsuit hands. Consider four-betting with premium hands (KK, AA, AKs, sometimes QQ/AKo) as a mix.

Limped Pots

If the HJ limps (uncommon but possible for deception) and the action goes heads-up versus the big blind, the strategy shifts to reading the flop. Typically, the HJ should raise most strong hands to build a pot, and check back marginal hands to control pot size.

Example Strategy Chart (Not Exact)

• Open raise: 2.5-3 big blinds with range described above.
• Facing three-bet: Call with pairs 77-JJ, suited connectors (e.g., 98s), and some suited aces; four-bet with KK+ and AKo (mix with calls).
• Facing check (from big blind): Continue with c-bets on favorable flops, check back weak hands.

Key Considerations

• Position: HJ has positional disadvantage versus cutoff/button if they call, but in a heads-up pot versus blinds, HJ has position on the big blind if the small blind folds. This positional edge allows more aggressive play.
• Opponent Type: Against tight opponents, open wider; against loose aggressive players, tighten up and trap with strong hands.
• Game Theory Optimal (GTO): GTO ranges for HJ in a heads-up pot are slightly tighter than cutoff but include balancing with some bluffs. Solvers suggest mixing small suited connectors to defend against three-bets.

Conclusion

HJ heads-up pot preflop strategy is about exploiting position and stack dynamics while maintaining a balanced range. Adjust to opponents, but a solid default range and post-flop plan provide a strong foundation.
