What is a good UTG opening range in 6-max?
The GTO solver UTG first-in range at 100bb raises 17.7% and folds 82.3% of hands.
Under the gun acts first, with five players still to act. This chart compares each authored opponent model in that first-in spot. Some models raise or fold; others also limp. Read the full action mix rather than treating every highlighted hand as a raise.
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. UTG is first in; no prior raise or limp. Limp means matching the big blind.
Quick tip: UTG has five players behind. Compare both raise frequency and limp frequency when identifying the model’s tendencies.
UTG 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 Hijack open range raises 21.5% of hands at 100bb, 3.8 points wider 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.
