In equity, AKs against ATs stands at 70.74% to 29.26%, a gap of 41.48 points. ## AKs against ATs: the numbers **Exact preflop results for AKs against ATs, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | AKs | 68.637 | 4.212 | 27.151 | 70.743 | | ATs | 27.151 | 4.212 | 68.637 | 29.257 | Each side holds one of the suited hands: AKs and ATs. 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, 70.74% to 29.26%, but ATs still wins often enough that one hand proves nothing. Ties are part of the picture: 4.21% of boards end in a split pot, and each side counts that as half a win. The hand ranking puts AKs at 8 and ATs at 13 out of 169 starting hands. **Boards behind the percentages: 20,547,648 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | AKs | 14,103,000 | 865,000 | 5,579,000 | | ATs | 5,579,000 | 865,000 | 14,103,000 | The total is exact: 12 specific deals times 1,712,304 boards.
