A3s leads 57.29% to 42.71% before the flop, counted exactly over every board, with the split by flop type and suit. Averaged over every possible board, A3s is ahead of T9o by 14.58 points of equity, 57.29% to 42.71%. ## A3s against T9o: the numbers **Exact preflop results for A3s against T9o, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | A3s | 57.063 | 0.461 | 42.476 | 57.293 | | T9o | 42.476 | 0.461 | 57.063 | 42.707 | The first hand is a suited hand; the second is an offsuit hand. With no overlap in ranks, every card that pairs one hand is a card that does not pair the other. The lead is steady rather than large, and the flop still has plenty of say in who wins. A split pot comes up on 0.46% of boards, so the wins and the equity differ by half of that. By strength against a random hand, A3s holds place 38 of 169 and T9o holds place 78. **Boards behind the percentages: 82,190,592 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | A3s | 46,900,000 | 379,000 | 34,911,000 | | T9o | 34,911,000 | 379,000 | 46,900,000 | Exact total: 48 deals times 1,712,304 boards.
