Counting every board, the equity split is 60.61% for 64s and 39.39% for 54s, so 64s leads by 21.22 points. ## 54s against 64s: the numbers **Exact preflop results for 54s against 64s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | 54s | 27.821 | 23.142 | 49.037 | 39.392 | | 64s | 49.037 | 23.142 | 27.821 | 60.608 | The matchup is suited hands on both sides, 54s against 64s. The two hands share a rank, and the one with the better other card dominates: it wins most kicker battles when that shared rank hits. The lead is steady rather than large, and the flop still has plenty of say in who wins. Split pots make up 23.14% of the boards, and both equity figures count them as half a win each. Place 136 of 169 belongs to 54s 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 | | --- | --- | --- | --- | | 54s | 5,717,000 | 4,755,000 | 10,076,000 | | 64s | 10,076,000 | 4,755,000 | 5,717,000 | Exact total: 12 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. **54s 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) | | --- | --- | --- | --- | --- | | 54s | 0.650 | 3.594 | 2.039 | 1.539 | | 64s | 1.539 | 2.039 | 3.594 | 0.650 | 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: 64s holds 62.15% on rainbow flops topped by a ten or better and 57.08% on monotone flops. 64s stays ahead on all five textures. **54s against 64s by flop texture, in percent** | Flop | Share of flops | 54s wins | Ties | 64s wins | 54s equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 25.844 | 25.711 | 24.270 | 50.019 | 37.846 | | Rainbow, nine or lower | 5.065 | 30.628 | 15.623 | 53.749 | 38.440 | | Two-tone | 46.543 | 29.487 | 20.322 | 50.191 | 39.648 | | Monotone | 5.215 | 33.867 | 18.104 | 48.029 | 42.919 | | Paired | 17.333 | 23.853 | 32.745 | 43.402 | 40.226 | Read the flop types this way: rainbow has three suits, two-tone has two cards of one suit, monotone has three, and paired repeats a rank. ## Compared with a random hand A random hand would give 54s 41.45% and 64s 41.33%. Against each other the change is -2.06 points for 54s and +19.28 for 64s. **54s 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 | | --- | --- | --- | --- | --- | | 54s, all flops | 39.392 | 41.453 | -2.061 | 0.95028 | | 54s, rainbow, ten or higher | 37.846 | 41.453 | -3.607 | 0.91299 | | 54s, rainbow, nine or lower | 38.440 | 41.453 | -3.013 | 0.92732 | | 54s, two-tone | 39.648 | 41.453 | -1.805 | 0.95646 | | 54s, monotone | 42.919 | 41.453 | +1.466 | 1.03537 | | 54s, paired | 40.226 | 41.453 | -1.227 | 0.97040 | | 64s, all flops | 60.608 | 41.333 | +19.275 | 1.46633 | | 64s, rainbow, ten or higher | 62.154 | 41.333 | +20.821 | 1.50374 | | 64s, rainbow, nine or lower | 61.560 | 41.333 | +20.227 | 1.48937 | | 64s, two-tone | 60.352 | 41.333 | +19.019 | 1.46014 | | 64s, monotone | 57.081 | 41.333 | +15.748 | 1.38100 | | 64s, paired | 59.774 | 41.333 | +18.441 | 1.44616 | ## Does a shared suit matter? Every legal deal of 54s against 64s leaves the hands with no suit in common, so the suit split does not apply here. **54s against 64s by suit overlap, in percent** | Deals | Specific deals | Share of deals | 54s wins | Ties | 64s wins | 54s equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 0 | 0.00 | not possible | not possible | not possible | not possible | | No shared suit | 12 | 100.00 | 27.821 | 23.142 | 49.037 | 39.392 | ## How often this matchup comes up The class pair covers 12 combinations of specific cards in a fixed seat order, 0.0007% of 1,624,350, and 24 (0.0015%) in either order. ## A worked example Say each player puts $100 in before the flop, making a $200 pot.
