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, 194 of those 202 combos are still available (8 are blocked by the cards 65s holds). 65s is ahead of 12 and behind 182.

Put 65s up against a UTG opening range — 202 combos, 15.2% of all hands — and the exact answer is 35.6% equity: 35.0% outright wins, 63.7% losses and 1.3% chops. Your own two cards remove 8 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 12 of the 194 combos still live (6%) — the rest of the range is level with or in front of you, which is why the figure sits below even money.
The range behind this number is not a guess. 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. 65s's worst spots in it are 66 (18.6%), 77 (18.7%) and 88 (19.9%) — and its best are 22 (52.0%), 33 (50.8%) and 44 (49.7%). Across the whole range 65s's equity swings from 18.6% at the bottom to 52.0% at the top — the single 35.6% headline is the combo-weighted average of all of it.
Facing a UTG opening range, 35.6% is a raise-or-fold number, not a call-and-see number: 65s is behind the range, so it needs position, implied odds or fold equity rather than showdown value. Against 15.2% of hands, you are priced in against a pot-sized bet (which needs about 33%).

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 65s runs at 35.6% against it rather than against a random hand.
Does 65s do better against a wider or a tighter range?
Wider, almost always. 65s has 39.4% equity against a loose-passive calling range (50.5% of hands) but 32.5% 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.
