Averaged over every possible board, 66 is ahead of 76s by 21.04 points of equity, 60.52% to 39.48%. ## 66 against 76s: the numbers **Exact preflop results for 66 against 76s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | 66 | 59.111 | 2.821 | 38.068 | 60.521 | | 76s | 38.068 | 2.821 | 59.111 | 39.479 | We compare a pocket pair with a suited hand. One hand holds a card of the same rank as the pair, which removes a card the pair needs and makes the pair a bigger favorite. That is a modest edge, the kind that shows up over many hands and is easy to miss in one. The tie share is 2.82%: on those boards the pot is chopped and neither hand wins outright. The hand ranking puts 66 at 17 and 76s at 115 out of 169 starting hands. **Boards behind the percentages: 20,547,648 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | 66 | 12,146,000 | 580,000 | 7,822,000 | | 76s | 7,822,000 | 580,000 | 12,146,000 | The board total is exact, 12 deals at 1,712,304 boards each. Won, tied and lost counts are rounded to the nearest thousand from the five-decimal percentages. **66 against 76s read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | 66 | 1.533 | 1.692 | 2.627 | 0.652 | | 76s | 0.652 | 2.627 | 1.692 | 1.533 | In the last column, a pot-to-call ratio at or above the figure makes a call break even or better at this equity. ## Who is ahead on which flops The flop changes the picture. 66 does best on paired flops, at 65.66%, and worst on low rainbow flops (nine high or lower), at 45.73%. On low rainbow flops (nine high or lower) the numbers flip and 76s is the one ahead. **66 against 76s by flop texture, in percent** | Flop | Share of flops | 66 wins | Ties | 76s wins | 66 equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 25.786 | 63.305 | 1.807 | 34.888 | 64.209 | | Rainbow, nine or lower | 4.995 | 42.664 | 6.127 | 51.209 | 45.727 | | Two-tone | 46.236 | 57.196 | 2.338 | 40.466 | 58.365 | | Monotone | 5.152 | 56.344 | 3.270 | 40.386 | 57.979 | | Paired | 17.831 | 63.416 | 4.483 | 32.101 | 65.658 | Flop types: rainbow means three different suits, two-tone means one suit twice, monotone means one suit three times, paired means a repeated rank. ## Compared with a random hand Compared with a random opponent, this matchup shifts 66 from 63.29% by -2.77 points and 76s from 45.37% by -5.89 points. **66 and 76s here compared with each against a random hand, in percent** | Case | Equity here | Against a random hand | Change in points | Times the random-hand equity | | --- | --- | --- | --- | --- | | 66, all flops | 60.521 | 63.285 | -2.764 | 0.95632 | | 66, rainbow, ten or higher | 64.209 | 63.285 | +0.924 | 1.01460 | | 66, rainbow, nine or lower | 45.727 | 63.285 | -17.558 | 0.72256 | | 66, two-tone | 58.365 | 63.285 | -4.920 | 0.92226 | | 66, monotone | 57.979 | 63.285 | -5.306 | 0.91616 | | 66, paired | 65.658 | 63.285 | +2.373 | 1.03750 | | 76s, all flops | 39.479 | 45.372 | -5.893 | 0.87012 | | 76s, rainbow, ten or higher | 35.791 | 45.372 | -9.581 | 0.78883 | | 76s, rainbow, nine or lower | 54.273 | 45.372 | +8.901 | 1.19618 | | 76s, two-tone | 41.635 | 45.372 | -3.737 | 0.91764 | | 76s, monotone | 42.021 | 45.372 | -3.351 | 0.92614 | | 76s, paired | 34.342 | 45.372 | -11.030 | 0.75690 | ## Does a shared suit matter? 66 and 76s never overlap in suit in a legal deal, so the whole matchup sits in the no-shared-suit row. **66 against 76s by suit overlap, in percent** | Deals | Specific deals | Share of deals | 66 wins | Ties | 76s wins | 66 equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 0 | 0.00 | not possible | not possible | not possible | not possible | | No shared suit | 12 | 100.00 | 59.111 | 2.821 | 38.068 | 60.521 | ## How often this matchup comes up How often does it happen? 12 of the 1,624,350 ordered deals (0.0007%) are 66 against 76s, and 24 (0.0015%) if either hand may sit in either seat. ## A worked example With $100 from each side, the $200 pot is split on average as $121.04 for 66 and $78.96 for 76s; the first side gains $21.04 per all-in and the second gives up $21.04. Think in thousands: about 591 of 1,000 go to 66, about 381 go to 76s, and about 28 are chopped. ## The same matchup from the other side Read it from the other side: 76s against 66 is the same matchup with the numbers swapped, so 76s holds 39.48% and 66 holds 60.52%.
