What is a good hijack opening range in 6-max?
The GTO solver Hijack first-in range at 100bb raises 21.5% and folds 78.5% of hands.
The hijack acts after UTG folds, with the cutoff, button, and blinds still to act. Compare how the models allocate raises, limps, and folds from this seat. The chart describes their behavior, while your own decision also depends on the players behind.
The GTO solver chart is our CFR solver's 100bb ranges, with 2.5bb opens (3bb from the small blind). The other charts are the ranges Poker Shark's Arena opponents play, not recommendations for your own play. The Arena's GTO opponent is GTO-style: hand-written rules, a little tighter than a solver. The other types are modeled on real players. Percentages are how often each one takes each action.
Green is raise, blue is limp or call, and gray is fold. Each share fills that percentage of the cell. Raise includes all-in actions. The Arena charts specify no raise size. Use the hand lookup for exact percentages. These fixed snapshots do not expose a rake setting.
6-max, 100bb starting stacks, 0.5/1bb blinds. HJ is first in; no prior raise or limp. UTG folded. Limp means matching the big blind.
Quick tip: A wider first-in range can come from more limping as well as more raising. The two tendencies are shown separately.
Hijack opening range by the numbers
Fixed reference figures, independent of the chart selected above. First-in comparisons count raises only; defense comparisons count raises plus calls.
For comparison, the GTO solver UTG open range raises 17.7% of hands at 100bb, 3.8 points tighter than this seat. Figures count combos: pairs weigh six, suited hands four, and offsuit hands twelve. Limping is excluded from these raise-frequency comparisons.
Now play the spots, not just the chart.
Practice against opponents whose ranges are too loose, too tight, or too passive, and exploit the gap.
