Counting every board, the equity split is 62.00% for T9o and 38.00% for 64s, so T9o leads by 24.00 points. ## T9o against 64s: the numbers **Exact preflop results for T9o against 64s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | T9o | 61.129 | 1.745 | 37.126 | 62.002 | | 64s | 37.126 | 1.745 | 61.129 | 37.998 | One side is an offsuit hand, the other is a suited hand. With no overlap in ranks, every card that pairs one hand is a card that does not pair the other. The lead is steady rather than large, and the flop still has plenty of say in who wins. A split pot comes up on 1.75% of boards, so the wins and the equity differ by half of that. For context, T9o sits at number 78 of 169 starting hands and 64s at number 138 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 | | --- | --- | --- | --- | | T9o | 50,242,000 | 1,434,000 | 30,514,000 | | 64s | 30,514,000 | 1,434,000 | 50,242,000 | 48 specific deals times 1,712,304 boards gives the exact total. The won, tied and lost counts are approximations from the five-decimal percentages, rounded to the nearest thousand. **T9o 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) | | --- | --- | --- | --- | --- | | T9o | 1.632 | 1.636 | 2.694 | 0.613 | | 64s | 0.613 | 2.694 | 1.636 | 1.632 | The last column is the break-even price: the pot odds a call needs to offer, as a ratio of pot to call. ## Who is ahead on which flops If you know the kind of flop that came, the numbers shift: T9o holds 67.29% on rainbow flops topped by a ten or better and 48.44% on low rainbow flops (nine high or lower). 64s takes over on low rainbow flops (nine high or lower), so the favorite before the flop is the underdog on those boards. **T9o against 64s by flop texture, in percent** | Flop | Share of flops | T9o wins | Ties | 64s wins | T9o equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 25.341 | 66.720 | 1.136 | 32.144 | 67.288 | | Rainbow, nine or lower | 5.689 | 48.183 | 0.511 | 51.306 | 48.439 | | Two-tone | 46.667 | 60.379 | 0.960 | 38.661 | 60.859 | | Monotone | 5.212 | 58.674 | 2.936 | 38.390 | 60.142 | | Paired | 17.091 | 59.945 | 4.840 | 35.215 | 62.365 | 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 Each hand has a baseline against a random hand: 51.53% for T9o, 41.33% for 64s.
