The range this is computed against

Under the gun a competent 6-max regular opens roughly the top 15% of hands: every pocket pair, the suited aces (nut-flush and wheel blockers), suited broadways down to J9s, the strongest suited connectors, and only AJo+ / KQo offsuit — offsuit hands realise their equity badly from the worst seat at the table.

UTG open — 202 combos, 15.2% of all starting hands: AA, KK, QQ, JJ, TT, 99, 88, 77, 66, 55, 44, 33, 22, AKs, AQs, AJs, ATs, A9s, A5s, A4s, A3s, KQs, KJs, KTs, QJs, QTs, JTs, J9s, T9s, 98s, 87s, 76s, AKo, AQo, AJo, KQo

After card removal, 184 of those 202 combos are still available (18 are blocked by the cards JTs holds). JTs is ahead of 54 and behind 130.

Against a UTG opening range (202 combos, 15.2% of all hands), JTs runs at 42.4%. It wins 41.1% of runouts outright, loses 56.3% and splits the remaining 2.6%. Your own two cards remove 18 of those combos before the flop is even dealt — a blocker effect this number already accounts for, because every combo containing one of your exact cards is stripped out of the range first. You are ahead of only 54 of the 184 combos still live (29%) — the rest of the range is level with or in front of you, which is why the figure sits below even money.

Where does the range come from? Under the gun a competent 6-max regular opens roughly the top 15% of hands: every pocket pair, the suited aces (nut-flush and wheel blockers), suited broadways down to J9s, the strongest suited connectors, and only AJo+ / KQo offsuit — offsuit hands realise their equity badly from the worst seat at the table. Broken down hand by hand, JTs does worst against JJ (17.8%), QQ (18.3%) and KK (19.8%) and best against T9s (70.1%), J9s (69.0%) and 98s (64.7%). Across the whole range JTs's equity swings from 17.8% at the bottom to 70.1% at the top — the single 42.4% headline is the combo-weighted average of all of it.

The practical read on 42.4% against a UTG opening range: flatting in position is the only comfortable line; jamming into a 15.2% range as a 42.4% underdog needs the fold equity to carry it.

JTs vs UTG open FAQ

What hands are in a UTG opening range?

36 hand classes and 202 combos — 15.2% of the 1,326 possible starting hands. By combo count it is 39% pocket pairs (13 pairs, 78 combos), 38% suited hands (19 classes, 76 combos) and 24% offsuit hands (4 classes, 48 combos). That shape is why JTs runs at 42.4% against it rather than against a random hand.

Does JTs do better against a wider or a tighter range?

Wider, almost always. JTs has 49.4% equity against a loose-passive calling range (50.5% of hands) but 32.3% against a 4-betting range (3.2%). Equity against a range is mostly a question of how many weak hands the range still contains — which is why the same holding can be a monster against a button open and a fold against a 4-bet.
