A9o leads 56.96% to 43.04% before the flop, counted exactly over every board, with the split by flop type and suit. The exact count puts A9o at 56.96% and QTo at 43.04% when the two hands see all five board cards. ## A9o against QTo: the numbers **Exact preflop results for A9o against QTo, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | A9o | 56.749 | 0.420 | 42.831 | 56.959 | | QTo | 42.831 | 0.420 | 56.749 | 43.041 | A9o meets QTo, and both are offsuit hands. With no overlap in ranks, every card that pairs one hand is a card that does not pair the other. A 13.92 point lead is real, and QTo still takes about 428 of every 1,000 deals outright. 0.42% of boards are ties, so the equity of each hand is its win rate plus half of that. A9o ranks number 25 of 169 starting hands, and QTo ranks number 47, by equity against a random hand. **Boards behind the percentages: 246,571,776 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | A9o | 139,927,000 | 1,036,000 | 105,609,000 | | QTo | 105,609,000 | 1,036,000 | 139,927,000 | 144 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. **A9o against QTo read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | A9o | 1.323 | 1.762 | 2.335 | 0.756 | | QTo | 0.756 | 2.335 | 1.762 | 1.323 | The final column gives the least the pot must offer for each unit called for a call to break even at this equity. ## Who is ahead on which flops Break the boards down by their first three cards and A9o is strongest on low rainbow flops (nine high or lower) (73.87%) and weakest on rainbow flops topped by a ten or better (50.53%). A9o stays ahead on all five textures, but the swing between them is large, so how the flop looks matters a great deal. **A9o against QTo by flop texture, in percent** | Flop | Share of flops | A9o wins | Ties | QTo wins | A9o equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 24.110 | 50.458 | 0.153 | 49.389 | 50.534 | | Rainbow, nine or lower | 7.042 | 73.465 | 0.804 | 25.731 | 73.867 | | Two-tone | 46.606 | 55.530 | 0.287 | 44.183 | 55.673 | | Monotone | 5.151 | 53.612 | 1.681 | 44.707 | 54.453 | | Paired | 17.091 | 63.007 | 0.620 | 36.373 | 63.317 | 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 Each hand has a baseline against a random hand: 60.77% for A9o, 57.29% for QTo. Here the change is -3.81 and -14.25 points. **A9o and QTo 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 | | --- | --- | --- | --- | --- | | A9o, all flops | 56.959 | 60.773 | -3.814 | 0.93724 | | A9o, rainbow, ten or higher | 50.534 | 60.773 | -10.239 | 0.83152 | | A9o, rainbow, nine or lower | 73.867 | 60.773 | +13.094 | 1.21546 | | A9o, two-tone | 55.673 | 60.773 | -5.100 | 0.91608 | | A9o, monotone | 54.453 | 60.773 | -6.320 | 0.89601 | | A9o, paired | 63.317 | 60.773 | +2.544 | 1.04186 | | QTo, all flops | 43.041 | 57.291 | -14.250 | 0.75127 | | QTo, rainbow, ten or higher | 49.466 | 57.291 | -7.825 | 0.86342 | | QTo, rainbow, nine or lower | 26.133 | 57.291 | -31.158 | 0.45614 | | QTo, two-tone | 44.327 | 57.291 | -12.964 | 0.77372 | | QTo, monotone | 45.547 | 57.291 | -11.744 | 0.79501 | | QTo, paired | 36.683 | 57.291 | -20.608 | 0.64029 | ## Does a shared suit matter?
