Averaged over every possible board, QTo is ahead of T9o by 44.52 points of equity, 72.26% to 27.74%. ## QTo against T9o: the numbers **Exact preflop results for QTo against T9o, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | QTo | 70.164 | 4.185 | 25.651 | 72.256 | | T9o | 25.651 | 4.185 | 70.164 | 27.744 | Here offsuit hands face each other, QTo on one side and T9o on the other. Sharing a rank is the signature of a dominated hand, since the weaker hand is usually out-kicked when the shared rank shows up. A lead of 44.52 points is large but not decisive: T9o still takes about 256 of every 1,000 deals. A split pot comes up on 4.19% of boards, so the wins and the equity differ by half of that. The hand ranking puts QTo at 47 and T9o at 78 out of 169 starting hands. **Boards behind the percentages: 184,928,832 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | QTo | 129,753,000 | 7,739,000 | 47,436,000 | | T9o | 47,436,000 | 7,739,000 | 129,753,000 | 108 specific deals times 1,712,304 boards gives the exact total.
