A2s leads 56.62% to 43.38% before the flop, counted exactly over every board, with the split by flop type and suit. Averaged over every possible board, A2s is ahead of KTs by 13.24 points of equity, 56.62% to 43.38%. ## KTs against A2s: the numbers **Exact preflop results for KTs against A2s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | KTs | 43.106 | 0.545 | 56.349 | 43.378 | | A2s | 56.349 | 0.545 | 43.106 | 56.622 | The matchup is suited hands on both sides, KTs against A2s. Neither hand shares a rank with the other, so this is a contest of high cards, connection and suits. That is a modest edge, the kind that shows up over many hands and is easy to miss in one. About 0.55% of boards chop the pot, which is why equity sits slightly above the win figure for both hands. KTs ranks number 22 of 169 starting hands, and A2s ranks number 46, by equity against a random hand. **Boards behind the percentages: 27,396,864 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | KTs | 11,810,000 | 149,000 | 15,438,000 | | A2s | 15,438,000 | 149,000 | 11,810,000 | Exact total: 16 deals times 1,712,304 boards.
