If TT and A2s get all the chips in before the flop, TT owns 67.69% of the pot in the long run and A2s owns 32.31%. ## TT against A2s: the numbers **Exact preflop results for TT against A2s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | TT | 67.471 | 0.431 | 32.098 | 67.686 | | A2s | 32.098 | 0.431 | 67.471 | 32.314 | TT and A2s are a pocket pair and a suited hand, in that order. One of the other hand's cards outranks the pair and one is below it, which makes this a closer race than a pair against two small cards. That is a clear edge, 67.69% to 32.31%, but A2s still wins often enough that one hand proves nothing. Split pots make up 0.43% of the boards, and both equity figures count them as half a win each. TT ranks number 5 of 169 starting hands, and A2s ranks number 46, by equity against a random hand. **Boards behind the percentages: 41,095,296 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | TT | 27,727,000 | 177,000 | 13,191,000 | | A2s | 13,191,000 | 177,000 | 27,727,000 | The board total is exact, 24 deals at 1,712,304 boards each. Won, tied and lost counts are rounded to the nearest thousand from the five-decimal percentages. **TT against A2s read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | TT | 2.095 | 1.482 | 3.115 | 0.477 | | A2s | 0.477 | 3.115 | 1.482 | 2.095 | 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 By flop texture, TT's equity runs from 63.35% on monotone flops up to 75.59% on low rainbow flops (nine high or lower).

TT does better with a shared suit, by 0.59 points. **TT against A2s by suit overlap, in percent** | Deals | Specific deals | Share of deals | TT wins | Ties | A2s wins | TT equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 12 | 50.00 | 67.745 | 0.476 | 31.779 | 67.983 | | No shared suit | 12 | 50.00 | 67.197 | 0.386 | 32.417 | 67.390 | ## How often this matchup comes up The class pair covers 24 combinations of specific cards in a fixed seat order, 0.0015% of 1,624,350, and 48 (0.0030%) in either order. ## A worked example Try it with money: two players each put in $100 and the whole board runs out every possible way.
