In equity, ATs against KTo stands at 75.26% to 24.74%, a gap of 50.52 points. ## ATs against KTo: the numbers **Exact preflop results for ATs against KTo, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | ATs | 74.301 | 1.925 | 23.774 | 75.263 | | KTo | 23.774 | 1.925 | 74.301 | 24.737 | One side is a suited hand, the other is an offsuit hand. The two hands share a rank, and the one with the better other card dominates: it wins most kicker battles when that shared rank hits. A lead of 50.52 points is large but not decisive: KTo still takes about 238 of every 1,000 deals. The tie share is 1.93%: on those boards the pot is chopped and neither hand wins outright. By strength against a random hand, ATs holds place 13 of 169 and KTo holds place 33. **Boards behind the percentages: 61,642,944 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | ATs | 45,801,000 | 1,187,000 | 14,655,000 | | KTo | 14,655,000 | 1,187,000 | 45,801,000 | The board total is exact, 36 deals at 1,712,304 boards each.
