The exact count puts 44 at 61.11% and 64s at 38.89% when the two hands see all five board cards. ## 44 against 64s: the numbers **Exact preflop results for 44 against 64s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | 44 | 59.303 | 3.623 | 37.074 | 61.114 | | 64s | 37.074 | 3.623 | 59.303 | 38.886 | The first hand is a pocket pair; the second is a suited hand. The pair already holds one of the other hand's ranks, and that overlap cuts down the cards the other hand can pair with. 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 3.62% of boards, so the wins and the equity differ by half of that. Place 48 of 169 belongs to 44 and place 138 belongs to 64s in the ranking against a random hand. **Boards behind the percentages: 20,547,648 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | 44 | 12,185,000 | 744,000 | 7,618,000 | | 64s | 7,618,000 | 744,000 | 12,185,000 | 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. **44 against 64s read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | 44 | 1.572 | 1.686 | 2.697 | 0.636 | | 64s | 0.636 | 2.697 | 1.686 | 1.572 | 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 Rainbow flops topped by a ten or better are the best for 44 (65.45%); low rainbow flops (nine high or lower) are the worst (46.08%). 64s takes over on low rainbow flops (nine high or lower), so the favorite before the flop is the underdog on those boards. **44 against 64s by flop texture, in percent** | Flop | Share of flops | 44 wins | Ties | 64s wins | 44 equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 25.786 | 64.411 | 2.079 | 33.510 | 65.451 | | Rainbow, nine or lower | 4.995 | 43.125 | 5.901 | 50.974 | 46.075 | | Two-tone | 46.236 | 58.065 | 2.529 | 39.406 | 59.330 | | Monotone | 5.152 | 56.394 | 3.936 | 39.670 | 58.362 | | Paired | 17.831 | 60.494 | 7.965 | 31.541 | 64.477 | A rainbow flop shows three suits, a two-tone flop repeats one suit, a monotone flop is a single suit, and a paired flop repeats a rank. ## Compared with a random hand The table below sets each hand against its own random-hand baseline: a change of +4.09 points for 44, from 57.02%, and -2.44 for 64s, from 41.33%. **44 and 64s 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 | | --- | --- | --- | --- | --- | | 44, all flops | 61.114 | 57.023 | +4.091 | 1.07174 | | 44, rainbow, ten or higher | 65.451 | 57.023 | +8.428 | 1.14780 | | 44, rainbow, nine or lower | 46.075 | 57.023 | -10.948 | 0.80801 | | 44, two-tone | 59.330 | 57.023 | +2.307 | 1.04046 | | 44, monotone | 58.362 | 57.023 | +1.339 | 1.02348 | | 44, paired | 64.477 | 57.023 | +7.454 | 1.13072 | | 64s, all flops | 38.886 | 41.333 | -2.447 | 0.94080 | | 64s, rainbow, ten or higher | 34.549 | 41.333 | -6.784 | 0.83587 | | 64s, rainbow, nine or lower | 53.925 | 41.333 | +12.592 | 1.30465 | | 64s, two-tone | 40.670 | 41.333 | -0.663 | 0.98396 | | 64s, monotone | 41.638 | 41.333 | +0.305 | 1.00738 | | 64s, paired | 35.523 | 41.333 | -5.810 | 0.85943 | ## Does a shared suit matter? For this pair the shared-suit row is empty: the two hands cannot both own a card of one suit without reusing a card. **44 against 64s by suit overlap, in percent** | Deals | Specific deals | Share of deals | 44 wins | Ties | 64s wins | 44 equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 0 | 0.00 | not possible | not possible | not possible | not possible | | No shared suit | 12 | 100.00 | 59.303 | 3.623 | 37.074 | 61.114 | ## How often this matchup comes up You will meet this exact matchup 0.0015% of the time in a random heads-up deal: 24 of 1,624,350, counting either seat order. ## A worked example Worked example: both players commit $100, so $200 sits in the middle.
