If AQs and A2s get all the chips in before the flop, AQs owns 70.58% of the pot in the long run and A2s owns 29.42%. ## AQs against A2s: the numbers **Exact preflop results for AQs against A2s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | AQs | 67.782 | 5.602 | 26.616 | 70.583 | | A2s | 26.616 | 5.602 | 67.782 | 29.417 | Two suited hands meet here: AQs against A2s. 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. That is a clear edge, 70.58% to 29.42%, but A2s still wins often enough that one hand proves nothing. Ties are part of the picture: 5.60% of boards end in a split pot, and each side counts that as half a win. Place 10 of 169 belongs to AQs and place 46 belongs to A2s in the ranking against a random hand. **Boards behind the percentages: 20,547,648 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | AQs | 13,928,000 | 1,151,000 | 5,469,000 | | A2s | 5,469,000 | 1,151,000 | 13,928,000 | Exact total: 12 deals times 1,712,304 boards.
