Aces vs a small pair: the odds
What are the odds of pocket aces against a small pocket pair?
| Hand | Cards | Wins | Equity |
|---|---|---|---|
| Pocket aces | A♥ A♦ | 81.3% | 81.6% |
| Pocket fives | 5♥ 5♦ | 18.2% | 18.4% |
| Split pot | — | 0.49% | — |
All-in before the flop, with five cards to come. Equity is each hand's average share of the pot — outright wins plus half of the split pots. Computed by enumerating all 1,712,304 possible boards with this site's own engine, so these are exact figures rather than a simulation.
Why the number looks like that
Barely different from aces against kings, which surprises people. A small pair is not much worse off than a big one — it still wins by hitting its own rank — and against aces specifically it loses only a sliver of equity because its straight chances are slightly worse.
