66 against A6s: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| 66 | 64.188 | 2.619 | 33.193 | 65.498 |
| A6s | 33.193 | 2.619 | 64.188 | 34.502 |
66 and A6s are a pocket pair and a suited hand, in that order. The non-pair hand shares a rank with the pair, so two of its outs for pairing are blocked by the pair itself.
That is a clear edge, 65.50% to 34.50%, but A6s still wins often enough that one hand proves nothing. A split pot comes up on 2.62% of boards, so the wins and the equity differ by half of that.
Among the 169 starting hands, 66 is number 17 and A6s is number 31 by strength against a random hand.
