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.

After card removal, 179 of those 202 combos are still available (23 are blocked by the cards A5s holds). A5s is ahead of 68 and behind 111.

A5s has 42.8% equity all-in preflop against a UTG opening range — 202 combos, 15.2% of all hands. Ace-Five Suited wins the pot outright 40.5% of the time, loses 54.8% and chops 4.7%. Your own two cards remove 23 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 68 of the 179 combos still live (38%) — the rest of the range is level with or in front of you, which is why the figure sits below even money.

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. Inside that range, the combos that hurt A5s most are AA (13.3%), AKs (30.2%) and AQs (30.7%); the ones you want to see are KQo (60.3%), KQs (57.5%) and KJs (57.2%). Across the whole range A5s's equity swings from 13.3% at the bottom to 60.3% at the top — the single 42.8% headline is the combo-weighted average of all of it.

The practical read on 42.8% against a UTG opening range: flatting in position is the only comfortable line; jamming into a 15.2% range as a 42.8% underdog needs the fold equity to carry it.

A5s 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 A5s runs at 42.8% against it rather than against a random hand.

Does A5s do better against a wider or a tighter range?

Wider, almost always. A5s has 53.4% equity against a loose-passive calling range (50.5% of hands) but 34.2% 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.
