If ATo and 53s get all the chips in before the flop, ATo owns 60.65% of the pot in the long run and 53s owns 39.35%. ## ATo against 53s: the numbers **Exact preflop results for ATo against 53s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | ATo | 60.398 | 0.509 | 39.093 | 60.652 | | 53s | 39.093 | 0.509 | 60.398 | 39.348 | Here an offsuit hand (ATo) meets a suited hand (53s). With no overlap in ranks, every card that pairs one hand is a card that does not pair the other. ATo is ahead, but 53s is far from dead: it takes 391 of every 1,000 deals outright. Split pots make up 0.51% of the boards, and both equity figures count them as half a win each. For context, ATo sits at number 19 of 169 starting hands and 53s at number 146 when each is run against a random hand. **Boards behind the percentages: 82,190,592 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | ATo | 49,641,000 | 418,000 | 32,131,000 | | 53s | 32,131,000 | 418,000 | 49,641,000 | The total is exact: 48 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. **ATo 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) | | --- | --- | --- | --- | --- | | ATo | 1.541 | 1.656 | 2.558 | 0.649 | | 53s | 0.649 | 2.558 | 1.656 | 1.541 | 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 Break the boards down by their first three cards and ATo is strongest on rainbow flops topped by a ten or better (68.20%) and weakest on low rainbow flops (nine high or lower) (36.71%). The overall edge for ATo hides low rainbow flops (nine high or lower), where 53s comes out in front. **ATo against 53s by flop texture, in percent** | Flop | Share of flops | ATo wins | Ties | 53s wins | ATo equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 24.717 | 68.083 | 0.234 | 31.683 | 68.200 | | Rainbow, nine or lower | 6.313 | 36.296 | 0.825 | 62.879 | 36.709 | | Two-tone | 46.667 | 58.775 | 0.330 | 40.895 | 58.940 | | Monotone | 5.212 | 57.469 | 2.486 | 40.045 | 58.712 | | Paired | 17.091 | 63.511 | 0.674 | 35.815 | 63.848 | 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 A random hand would give ATo 62.72% and 53s 39.69%. Against each other the change is -2.07 points for ATo and -0.34 for 53s. **ATo and 53s 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 | | --- | --- | --- | --- | --- | | ATo, all flops | 60.652 | 62.722 | -2.070 | 0.96700 | | ATo, rainbow, ten or higher | 68.200 | 62.722 | +5.478 | 1.08734 | | ATo, rainbow, nine or lower | 36.709 | 62.722 | -26.013 | 0.58527 | | ATo, two-tone | 58.940 | 62.722 | -3.782 | 0.93970 | | ATo, monotone | 58.712 | 62.722 | -4.010 | 0.93607 | | ATo, paired | 63.848 | 62.722 | +1.126 | 1.01795 | | 53s, all flops | 39.348 | 39.693 | -0.345 | 0.99131 | | 53s, rainbow, ten or higher | 31.800 | 39.693 | -7.893 | 0.80115 | | 53s, rainbow, nine or lower | 63.291 | 39.693 | +23.598 | 1.59451 | | 53s, two-tone | 41.060 | 39.693 | +1.367 | 1.03444 | | 53s, monotone | 41.288 | 39.693 | +1.595 | 1.04018 | | 53s, paired | 36.152 | 39.693 | -3.541 | 0.91079 | ## Does a shared suit matter? Suit overlap shows up in the numbers. With a suit in common ATo has 61.35% equity, and with none in common it has 59.95%. ATo does better with a shared suit, by 1.40 points. **ATo against 53s by suit overlap, in percent** | Deals | Specific deals | Share of deals | ATo wins | Ties | 53s wins | ATo equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 24 | 50.00 | 61.077 | 0.549 | 38.374 | 61.351 | | No shared suit | 24 | 50.00 | 59.718 | 0.469 | 39.813 | 59.953 | ## How often this matchup comes up Out of 1,624,350 ways to deal two seats two cards each, 48 are ATo in one seat and 53s in the other (0.0030%); with the seats swapped too, 96 (0.0059%). ## A worked example Take a $200 pot built from $100 each. ATo's equity of 60.65% is worth $121.30, a $21.30 edge, and 53s' 39.35% is worth $78.70, which is $21.30 under its stake. Out of 1,000 deals you should see around 604 outright wins for ATo, 391 for 53s, and 5 split pots. ## The same matchup from the other side Read it from the other side: 53s against ATo is the same matchup with the numbers swapped, so 53s holds 39.35% and ATo holds 60.65%.
