Averaged over every possible board, ATs is ahead of A6s by 37.30 points of equity, 68.65% to 31.35%. ## ATs against A6s: the numbers **Exact preflop results for ATs against A6s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | ATs | 63.979 | 9.342 | 26.679 | 68.650 | | A6s | 26.679 | 9.342 | 63.979 | 31.350 | Each side holds one of the suited hands: ATs and A6s. The two hands share a rank, and the one with the better other card dominates: it wins most kicker battles when that shared rank hits. That is a clear edge, 68.65% to 31.35%, but A6s still wins often enough that one hand proves nothing. 9.34% of boards are ties, so the equity of each hand is its win rate plus half of that. Among the 169 starting hands, ATs is number 13 and A6s is number 31 by strength against a random hand. **Boards behind the percentages: 20,547,648 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | ATs | 13,146,000 | 1,920,000 | 5,482,000 | | A6s | 5,482,000 | 1,920,000 | 13,146,000 | The total is exact: 12 specific deals times 1,712,304 boards. The three counts are approximate, worked out from the percentages to five decimals and rounded to the nearest thousand. **ATs against A6s read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | ATs | 2.190 | 1.563 | 3.748 | 0.457 | | A6s | 0.457 | 3.748 | 1.563 | 2.190 | 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 ATs prefers rainbow flops topped by a ten or better, where it holds 75.05%, and likes low rainbow flops (nine high or lower) least, where it holds 58.38%. ATs stays ahead on all five textures, but the swing between them is large, so how the flop looks matters a great deal. **ATs against A6s by flop texture, in percent** | Flop | Share of flops | ATs wins | Ties | A6s wins | ATs equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 23.867 | 70.974 | 8.158 | 20.868 | 75.053 | | Rainbow, nine or lower | 7.042 | 57.094 | 2.566 | 40.340 | 58.377 | | Two-tone | 46.543 | 65.376 | 6.249 | 28.375 | 68.501 | | Monotone | 5.215 | 59.457 | 7.478 | 33.065 | 63.196 | | Paired | 17.333 | 54.755 | 22.588 | 22.657 | 66.049 | 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 How much does the opponent matter?

A shared suit is impossible for this matchup, so ATs' 68.65% is the answer for every suit pattern. **ATs against A6s by suit overlap, in percent** | Deals | Specific deals | Share of deals | ATs wins | Ties | A6s wins | ATs equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 0 | 0.00 | not possible | not possible | not possible | not possible | | No shared suit | 12 | 100.00 | 63.979 | 9.342 | 26.679 | 68.650 | ## How often this matchup comes up This page stands for 12 specific-card matchups (0.0007% of 1,624,350 ordered deals), or 24 once you count the seats both ways (0.0015%). ## A worked example Try it with money: two players each put in $100 and the whole board runs out every possible way.
