Before any board card is dealt, AQo holds 69.37% equity against ATs, which leaves ATs with 30.63%. ## ATs against AQo: the numbers **Exact preflop results for ATs against AQo, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | ATs | 27.873 | 5.519 | 66.608 | 30.632 | | AQo | 66.608 | 5.519 | 27.873 | 69.368 | ATs is a suited hand and AQo is an offsuit hand. Sharing a rank is the signature of a dominated hand, since the weaker hand is usually out-kicked when the shared rank shows up. That is a clear edge, 69.37% to 30.63%, but ATs still wins often enough that one hand proves nothing. Of every 100 boards, about 5.52 are split pots, and the equity figures already include them. Among the 169 starting hands, ATs is number 13 and AQo is number 14 by strength against a random hand. **Boards behind the percentages: 61,642,944 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | ATs | 17,182,000 | 3,402,000 | 41,059,000 | | AQo | 41,059,000 | 3,402,000 | 17,182,000 | Exact total: 36 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. **ATs against AQo 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 | 0.442 | 3.588 | 1.501 | 2.265 | | AQo | 2.265 | 1.501 | 3.588 | 0.442 | 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 Low rainbow flops (nine high or lower) are the best for AQo (80.00%); monotone flops are the worst (64.19%).
