K9o leads 53.50% to 46.50% before the flop, counted exactly over every board, with the split by flop type and suit. The exact count puts K9o at 53.50% and JTs at 46.50% when the two hands see all five board cards. ## K9o against JTs: the numbers **Exact preflop results for K9o against JTs, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | K9o | 53.169 | 0.666 | 46.165 | 53.502 | | JTs | 46.165 | 0.666 | 53.169 | 46.498 | The first hand is an offsuit hand; the second is a suited hand. Neither hand shares a rank with the other, so this is a contest of high cards, connection and suits. K9o leads by less than 7 points of equity, so the result of any one deal is close to a toss-up. Of every 100 boards, about 0.67 are split pots, and the equity figures already include them. By strength against a random hand, K9o holds place 40 of 169 and JTs holds place 45. **Boards behind the percentages: 82,190,592 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | K9o | 43,700,000 | 547,000 | 37,943,000 | | JTs | 37,943,000 | 547,000 | 43,700,000 | The board total is exact, 48 deals at 1,712,304 boards each. Won, tied and lost counts are rounded to the nearest thousand from the five-decimal percentages. **K9o against JTs read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | K9o | 1.151 | 1.881 | 2.166 | 0.869 | | JTs | 0.869 | 2.166 | 1.881 | 1.151 | 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 If you know the kind of flop that came, the numbers shift: K9o holds 67.78% on low rainbow flops (nine high or lower) and 49.63% on rainbow flops topped by a ten or better. Watch for rainbow flops topped by a ten or better: on those flops JTs holds the better equity. **K9o against JTs by flop texture, in percent** | Flop | Share of flops | K9o wins | Ties | JTs wins | K9o equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 23.988 | 49.483 | 0.297 | 50.220 | 49.631 | | Rainbow, nine or lower | 7.042 | 67.407 | 0.742 | 31.851 | 67.778 | | Two-tone | 46.667 | 51.155 | 0.371 | 48.474 | 51.341 | | Monotone | 5.212 | 50.666 | 2.452 | 46.882 | 51.892 | | Paired | 17.091 | 58.740 | 1.414 | 39.846 | 59.447 | Flop types: rainbow means three different suits, two-tone means one suit twice, monotone means one suit three times, paired means a repeated rank. ## Compared with a random hand Start from the random-hand figures, 57.81% for K9o and 57.53% for JTs.

Over every board, K9o's average share is $107.00 (a gain of $7.00) and JTs' is $93.00 (a loss of $7.00). Think in thousands: about 532 of 1,000 go to K9o, about 461 go to JTs, and about 7 are chopped. ## The same matchup from the other side One page covers both views.
