If ATs and QTo get all the chips in before the flop, ATs owns 73.76% of the pot in the long run and QTo owns 26.24%. ## ATs against QTo: the numbers **Exact preflop results for ATs against QTo, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | ATs | 72.852 | 1.823 | 25.325 | 73.763 | | QTo | 25.325 | 1.823 | 72.852 | 26.237 | Here a suited hand (ATs) meets an offsuit hand (QTo). Sharing a rank is the signature of a dominated hand, since the weaker hand is usually out-kicked when the shared rank shows up. ATs is well ahead, and QTo needs a specific kind of board to catch up. A split pot comes up on 1.82% of boards, so the wins and the equity differ by half of that. Ranked by equity against a random hand, ATs is number 13 of the 169 starting hands and QTo is number 47. **Boards behind the percentages: 61,642,944 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | ATs | 44,908,000 | 1,124,000 | 15,611,000 | | QTo | 15,611,000 | 1,124,000 | 44,908,000 | The board total is exact, 36 deals at 1,712,304 boards each. Won, tied and lost counts are rounded to the nearest thousand from the five-decimal percentages. **ATs 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) | | --- | --- | --- | --- | --- | | ATs | 2.811 | 1.373 | 3.949 | 0.356 | | QTo | 0.356 | 3.949 | 1.373 | 2.811 | 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 Across the five flop textures ATs' equity moves by 18.14 points, from 66.22% on monotone flops to 84.36% on low rainbow flops (nine high or lower).
