Among the 169 starting hands, AQo is number 14 and A5s is number 30 by strength against a random hand. **Boards behind the percentages: 61,642,944 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | AQo | 40,136,000 | 3,488,000 | 18,019,000 | | A5s | 18,019,000 | 3,488,000 | 40,136,000 | 36 specific deals times 1,712,304 boards gives the exact total.
