Dealt all in against each other, TT takes 68.43% of the pot on average and K9s takes the other 31.57%. ## TT against K9s: the numbers **Exact preflop results for TT against K9s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | TT | 68.233 | 0.399 | 31.368 | 68.432 | | K9s | 31.368 | 0.399 | 68.233 | 31.568 | The first hand is a pocket pair; the second is a suited hand. The pair sits between the other hand's two cards: one is higher and one is lower, so the pair is exposed to the higher card. That is a clear edge, 68.43% to 31.57%, but K9s still wins often enough that one hand proves nothing. Ties are 0.40% of the outcomes here; each tied board gives both hands half the pot. For context, TT sits at number 5 of 169 starting hands and K9s at number 29 when each is run against a random hand. **Boards behind the percentages: 41,095,296 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | TT | 28,041,000 | 164,000 | 12,891,000 | | K9s | 12,891,000 | 164,000 | 28,041,000 | Exact total: 24 deals times 1,712,304 boards. The other three counts come from the five-decimal percentages and are rounded to the nearest thousand, so read them as approximate. **TT against K9s read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | TT | 2.168 | 1.466 | 3.188 | 0.461 | | K9s | 0.461 | 3.188 | 1.466 | 2.168 | The final column gives the least the pot must offer for each unit called for a call to break even at this equity. ## Who is ahead on which flops Break the boards down by their first three cards and TT is strongest on low rainbow flops (nine high or lower) (79.85%) and weakest on monotone flops (63.68%).
