AKs vs a middle-position opening range: Equity & Strategy

Ace-King Suited (AKs) has 60.8% equity all-in preflop against a middle-position opening range — 258 combos, 19.5% of all starting hands. It wins 58.2% of runouts outright, loses 36.5% and chops 5.4%. These are exact figures from full board enumeration against every unblocked combo in the range, not a simulation.

The range this is computed against

With one fewer player left to act, middle position adds the rest of the suited aces, the suited one-gappers and a second layer of offsuit broadways (ATo, KJo) to the UTG chart — about 19% of hands.

MP open — 258 combos, 19.5% of all starting hands: AA, KK, QQ, JJ, TT, 99, 88, 77, 66, 55, 44, 33, 22, AKs, AQs, AJs, ATs, A9s, A8s, A7s, A6s, A5s, A4s, A3s, A2s, KQs, KJs, KTs, K9s, QJs, QTs, Q9s, JTs, J9s, T9s, T8s, 98s, 87s, 76s, 65s, AKo, AQo, AJo, ATo, KQo, KJo

After card removal, 215 of those 258 combos are still available (43 are blocked by the cards AKs holds). AKs is ahead of 140 and behind 75.

Easiest parts of the range for AKs

Put AKs up against a middle-position opening range — 258 combos, 19.5% of all hands — and the exact answer is 60.8% equity: 58.2% outright wins, 36.5% losses and 5.4% chops. Your own two cards remove 43 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 140 of the 215 combos you can still be facing (65%), which is what a 60.8% number actually looks like hand by hand.

The range behind this number is not a guess. With one fewer player left to act, middle position adds the rest of the suited aces, the suited one-gappers and a second layer of offsuit broadways (ATo, KJo) to the UTG chart — about 19% of hands. AKs's worst spots in it are AA (12.1%), KK (34.1%) and TT (45.9%) — and its best are KQo (75.6%), AQo (75.4%) and KJo (75.3%). Across the whole range AKs's equity swings from 12.1% at the bottom to 75.6% at the top — the single 60.8% headline is the combo-weighted average of all of it.

Facing a middle-position opening range, 60.8% is a raise-or-fold number, not a call-and-see number: AKs is in front of the average opener but not by enough to want a bloated pot out of position. Against 19.5% of hands, you are priced in against a pot-sized bet (which needs about 33%).

AKs vs MP open FAQ

What is AKs's equity against a middle-position opening range?

AKs has 60.8% equity all-in preflop against a middle-position opening range — it wins 58.2% of runouts outright, loses 36.5% and chops 5.4%. The range holds 258 combos (19.5% of all hands); AKs blocks 43 of them, leaving 215 live. This is exact full board enumeration, not a simulation.

Which hands in a middle-position opening range beat AKs?

AKs is behind 75 of the 215 live combos and ahead of the other 140. The worst matchups are AA (12.1%), KK (34.1%) and TT (45.9%); its best are KQo (75.6%), AQo (75.4%) and KJo (75.3%). Every figure is exact, computed against that hand's unblocked combos only.

What hands are in a middle-position opening range?

46 hand classes and 258 combos — 19.5% of the 1,326 possible starting hands. By combo count it is 30% pocket pairs (13 pairs, 78 combos), 42% suited hands (27 classes, 108 combos) and 28% offsuit hands (6 classes, 72 combos). That shape is why AKs runs at 60.8% against it rather than against a random hand.

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

Wider, almost always. AKs has 65.8% equity against a loose-passive calling range (50.5% of hands) but 48.2% 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.
