Over all 1,712,304 boards that can follow this deal, AKs finishes with 69.82% of the pot and A5s with 30.18%. ## AKs against A5s: the numbers **Exact preflop results for AKs against A5s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | AKs | 67.661 | 4.311 | 28.028 | 69.817 | | A5s | 28.028 | 4.311 | 67.661 | 30.183 | AKs meets A5s, and both are suited hands. Because the hands share one rank, the one with the higher kicker is ahead when that rank pairs and the other hand is mostly drawing. AKs is well ahead, and A5s needs a specific kind of board to catch up. A split pot comes up on 4.31% of boards, so the wins and the equity differ by half of that. Ranked by equity against a random hand, AKs is number 8 of the 169 starting hands and A5s is number 30. **Boards behind the percentages: 20,547,648 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | AKs | 13,903,000 | 886,000 | 5,759,000 | | A5s | 5,759,000 | 886,000 | 13,903,000 | The total is exact: 12 specific deals times 1,712,304 boards. The three counts are approximate, worked out from the percentages to five decimals and rounded to the nearest thousand. **AKs against A5s read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | AKs | 2.313 | 1.478 | 3.568 | 0.432 | | A5s | 0.432 | 3.568 | 1.478 | 2.313 | The last column is the smallest pot odds, written as a pot-to-call ratio, at which a call breaks even with this equity. ## Who is ahead on which flops The flop changes the picture.
