Put 99 up against a middle-position opening range — 258 combos, 19.5% of all hands — and the exact answer is 58.2% equity: 57.7% outright wins, 41.3% losses and 0.9% chops. Your own two cards remove 17 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 210 of the 241 combos you can still be facing (87%), which is what a 58.2% number actually looks like hand by hand.

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. Inside that range, the combos that hurt 99 most are TT (18.0%), JJ (18.4%) and QQ (18.8%); the ones you want to see are 98s (82.2%), 88 (81.9%) and 22 (81.8%). Across the whole range 99's equity swings from 18.0% at the bottom to 82.2% at the top — the single 58.2% headline is the combo-weighted average of all of it.

The practical read on 58.2% against a middle-position opening range: you can 3-bet for value or flat in position, but this is not a stack-off-preflop holding against a 19.5% opener.

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 99 runs at 58.2% against it rather than against a random hand.

Does 99 do better against a wider or a tighter range?

Wider, almost always. 99 has 64.9% equity against a loose-passive calling range (50.5% of hands) but 41.6% 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.
