Over all 1,712,304 boards that can follow this deal, ATs finishes with 63.15% of the pot and 53s with 36.85%. ## ATs against 53s: the numbers **Exact preflop results for ATs against 53s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | ATs | 62.869 | 0.555 | 36.576 | 63.146 | | 53s | 36.576 | 0.555 | 62.869 | 36.854 | This is a contest between two suited hands, ATs and 53s. The two hands share no rank, which makes this a pure matchup of card strength, straight chances and flush chances. That is a modest edge, the kind that shows up over many hands and is easy to miss in one. A split pot comes up on 0.56% of boards, so the wins and the equity differ by half of that. For context, ATs sits at number 13 of 169 starting hands and 53s at number 146 when each is run against a random hand. **Boards behind the percentages: 27,396,864 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | ATs | 17,224,000 | 152,000 | 10,021,000 | | 53s | 10,021,000 | 152,000 | 17,224,000 | Exact total: 16 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. **ATs against 53s 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 | 1.713 | 1.591 | 2.734 | 0.584 | | 53s | 0.584 | 2.734 | 1.591 | 1.713 | 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 If you know the kind of flop that came, the numbers shift: ATs holds 69.52% on rainbow flops topped by a ten or better and 39.10% on low rainbow flops (nine high or lower).
