If T9o and 54s get all the chips in before the flop, T9o owns 61.50% of the pot in the long run and 54s owns 38.50%. ## T9o against 54s: the numbers **Exact preflop results for T9o against 54s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | T9o | 60.607 | 1.778 | 37.615 | 61.496 | | 54s | 37.615 | 1.778 | 60.607 | 38.504 | We compare an offsuit hand with a suited hand. Neither hand shares a rank with the other, so this is a contest of high cards, connection and suits. T9o is ahead, but 54s is far from dead: it takes 376 of every 1,000 deals outright. About 1.78% of boards chop the pot, which is why equity sits slightly above the win figure for both hands. The hand ranking puts T9o at 78 and 54s at 136 out of 169 starting hands. **Boards behind the percentages: 82,190,592 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | T9o | 49,813,000 | 1,461,000 | 30,916,000 | | 54s | 30,916,000 | 1,461,000 | 49,813,000 | The board total is exact, 48 deals at 1,712,304 boards each.
