Easiest parts of the range for KK

Against a middle-position opening range (258 combos, 19.5% of all hands), KK runs at 75.1%. It wins 74.6% of runouts outright, loses 24.4% and splits the remaining 0.9%. Your own two cards remove 33 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 218 of the 225 combos you can still be facing (97%), which is what a 75.1% 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. KK's worst spots in it are AA (18.1%), KK (50.0%) and AKs (65.9%) — and its best are KQo (91.3%), KJo (90.9%) and K9s (87.1%). Across the whole range KK's equity swings from 18.1% at the bottom to 91.3% at the top — the single 75.1% headline is the combo-weighted average of all of it.

The practical read on 75.1% against a middle-position opening range: 3-bet and get money in — you dominate the opener's continuing range and every free card costs you value.

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

KK is behind 7 of the 225 live combos and ahead of the other 218. The worst matchups are AA (18.1%), KK (50.0%) and AKs (65.9%); its best are KQo (91.3%), KJo (90.9%) and K9s (87.1%). 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 KK runs at 75.1% against it rather than against a random hand.

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

Wider, almost always. KK has 78.7% equity against a loose-passive calling range (50.5% of hands) but 59.9% 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.
