The exact count puts TT at 72.08% and K9o at 27.92% when the two hands see all five board cards. ## TT against K9o: the numbers **Exact preflop results for TT against K9o, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | TT | 71.892 | 0.379 | 27.729 | 72.082 | | K9o | 27.729 | 0.379 | 71.892 | 27.918 | We compare a pocket pair with an offsuit 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. TT is the clear favorite, though K9o gets there on roughly one board in 4. About 0.38% of boards chop the pot, which is why equity sits slightly above the win figure for both hands. For context, TT sits at number 5 of 169 starting hands and K9o at number 40 when each is run against a random hand. **Boards behind the percentages: 123,285,888 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | TT | 88,633,000 | 467,000 | 34,186,000 | | K9o | 34,186,000 | 467,000 | 88,633,000 | The total is exact: 72 specific deals times 1,712,304 boards. The three counts are approximate, worked out from the percentages to five decimals and rounded to the nearest thousand. **TT against K9o 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 | 2.582 | 1.391 | 3.606 | 0.387 | | K9o | 0.387 | 3.606 | 1.391 | 2.582 | 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 By flop texture, TT's equity runs from 67.34% on monotone flops up to 82.63% on low rainbow flops (nine high or lower). TT stays ahead on all five textures, but the swing between them is large, so how the flop looks matters a great deal. **TT against K9o by flop texture, in percent** | Flop | Share of flops | TT wins | Ties | K9o wins | TT equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 23.988 | 68.968 | 0.175 | 30.857 | 69.056 | | Rainbow, nine or lower | 7.042 | 82.222 | 0.824 | 16.954 | 82.634 | | Two-tone | 46.485 | 71.441 | 0.310 | 28.249 | 71.596 | | Monotone | 5.151 | 66.490 | 1.699 | 31.811 | 67.340 | | Paired | 17.334 | 74.557 | 0.274 | 25.169 | 74.694 | A rainbow flop shows three suits, a two-tone flop repeats one suit, a monotone flop is a single suit, and a paired flop repeats a rank. ## Compared with a random hand Start from the random-hand figures, 75.01% for TT and 57.81% for K9o.

Looking only at deals where the hands share a suit, TT has 72.12%; looking only at deals where they do not, 71.89%. The two rows differ by only 0.23 points, so suits barely change this matchup. **TT against K9o by suit overlap, in percent** | Deals | Specific deals | Share of deals | TT wins | Ties | K9o wins | TT equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 60 | 83.33 | 71.922 | 0.395 | 27.683 | 72.119 | | No shared suit | 12 | 16.67 | 71.744 | 0.300 | 27.956 | 71.894 | ## How often this matchup comes up You will meet this exact matchup 0.0089% of the time in a random heads-up deal: 144 of 1,624,350, counting either seat order. ## A worked example Say each player puts $100 in before the flop, making a $200 pot.
