Dealt all in against each other, AA takes 78.99% of the pot on average and T8s takes the other 21.01%. ## AA against T8s: the numbers **Exact preflop results for AA against T8s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | AA | 78.811 | 0.351 | 20.838 | 78.986 | | T8s | 20.838 | 0.351 | 78.811 | 21.014 | One side is a pocket pair, the other is a suited hand. Here a pair faces two cards that are both smaller, so the other hand needs to pair up and still be behind. A lead of 57.98 points is large but not decisive: T8s still takes about 208 of every 1,000 deals. The tie share is 0.35%: on those boards the pot is chopped and neither hand wins outright. Ranked by equity against a random hand, AA is number 1 of the 169 starting hands and T8s is number 73. **Boards behind the percentages: 41,095,296 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | AA | 32,388,000 | 144,000 | 8,563,000 | | T8s | 8,563,000 | 144,000 | 32,388,000 | Exact total: 24 deals times 1,712,304 boards. The other three counts come from the five-decimal percentages and are rounded to the nearest thousand, so read them as approximate. **AA against T8s read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | AA | 3.759 | 1.269 | 4.799 | 0.266 | | T8s | 0.266 | 4.799 | 1.269 | 3.759 | The last column is the smallest pot odds, written as a pot-to-call ratio, at which a call breaks even with this equity. ## Who is ahead on which flops AA prefers paired flops, where it holds 83.12%, and likes monotone flops least, where it holds 73.68%.

AA does better with a shared suit, by 1.15 points. **AA against T8s by suit overlap, in percent** | Deals | Specific deals | Share of deals | AA wins | Ties | T8s wins | AA equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 12 | 50.00 | 79.364 | 0.393 | 20.243 | 79.560 | | No shared suit | 12 | 50.00 | 78.258 | 0.309 | 21.433 | 78.412 | ## How often this matchup comes up Exactly 24 specific deals fit this matchup in one seat order, which is 0.0015% of 1,624,350; both orders together give 48, or 0.0030%. ## A worked example A $100 all-in from each player makes a $200 pot, and the exact equity says AA gets $157.98 of it on average and T8s gets $42.02. Scaled to 1,000 deals, that is roughly 788 wins for AA, 208 for T8s and 4 chopped pots. ## The same matchup from the other side Read it from the other side: T8s against AA is the same matchup with the numbers swapped, so T8s holds 21.01% and AA holds 78.99%.
