In equity, ATs against JTs stands at 68.38% to 31.62%, a gap of 36.76 points. ## ATs against JTs: the numbers **Exact preflop results for ATs against JTs, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | ATs | 67.526 | 1.698 | 30.776 | 68.375 | | JTs | 30.776 | 1.698 | 67.526 | 31.625 | Both hands are suited hands: ATs and JTs. Sharing a rank is the signature of a dominated hand, since the weaker hand is usually out-kicked when the shared rank shows up. ATs is well ahead, and JTs needs a specific kind of board to catch up. Ties are 1.70% of the outcomes here; each tied board gives both hands half the pot. ATs ranks number 13 of 169 starting hands, and JTs ranks number 45, by equity against a random hand. **Boards behind the percentages: 20,547,648 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | ATs | 13,875,000 | 349,000 | 6,324,000 | | JTs | 6,324,000 | 349,000 | 13,875,000 | The board total is exact, 12 deals at 1,712,304 boards each. Won, tied and lost counts are rounded to the nearest thousand from the five-decimal percentages. **ATs 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) | | --- | --- | --- | --- | --- | | ATs | 2.162 | 1.481 | 3.249 | 0.463 | | JTs | 0.463 | 3.249 | 1.481 | 2.162 | The last column is the break-even price: the pot odds a call needs to offer, as a ratio of pot to call. ## Who is ahead on which flops Across the five flop textures ATs' equity moves by 14.71 points, from 62.13% on monotone flops to 76.84% on low rainbow flops (nine high or lower). ATs stays ahead on all five textures. **ATs against JTs by flop texture, in percent** | Flop | Share of flops | ATs wins | Ties | JTs wins | ATs equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 23.138 | 65.942 | 1.587 | 32.471 | 66.736 | | Rainbow, nine or lower | 7.771 | 76.098 | 1.492 | 22.410 | 76.844 | | Two-tone | 46.543 | 66.227 | 1.375 | 32.398 | 66.914 | | Monotone | 5.215 | 60.167 | 3.929 | 35.904 | 62.132 | | Paired | 17.333 | 71.498 | 2.135 | 26.367 | 72.566 | Read the flop types this way: rainbow has three suits, two-tone has two cards of one suit, monotone has three, and paired repeats a rank. ## Compared with a random hand Against one random hand instead, ATs holds 64.60% and JTs holds 57.53%. Facing each other changes that by +3.78 points for ATs and -25.91 points for JTs. **ATs and JTs here compared with each against a random hand, in percent** | Case | Equity here | Against a random hand | Change in points | Times the random-hand equity | | --- | --- | --- | --- | --- | | ATs, all flops | 68.375 | 64.602 | +3.773 | 1.05840 | | ATs, rainbow, ten or higher | 66.736 | 64.602 | +2.134 | 1.03303 | | ATs, rainbow, nine or lower | 76.844 | 64.602 | +12.242 | 1.18950 | | ATs, two-tone | 66.914 | 64.602 | +2.312 | 1.03579 | | ATs, monotone | 62.132 | 64.602 | -2.470 | 0.96177 | | ATs, paired | 72.566 | 64.602 | +7.964 | 1.12328 | | JTs, all flops | 31.625 | 57.528 | -25.903 | 0.54973 | | JTs, rainbow, ten or higher | 33.264 | 57.528 | -24.264 | 0.57822 | | JTs, rainbow, nine or lower | 23.156 | 57.528 | -34.372 | 0.40252 | | JTs, two-tone | 33.086 | 57.528 | -24.442 | 0.57513 | | JTs, monotone | 37.868 | 57.528 | -19.660 | 0.65825 | | JTs, paired | 27.434 | 57.528 | -30.094 | 0.47688 | ## Does a shared suit matter? For this pair the shared-suit row is empty: the two hands cannot both own a card of one suit without reusing a card. **ATs against JTs by suit overlap, in percent** | Deals | Specific deals | Share of deals | ATs wins | Ties | JTs wins | ATs equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 0 | 0.00 | not possible | not possible | not possible | not possible | | No shared suit | 12 | 100.00 | 67.526 | 1.698 | 30.776 | 68.375 | ## How often this matchup comes up How often does it happen? 12 of the 1,624,350 ordered deals (0.0007%) are ATs against JTs, and 24 (0.0015%) if either hand may sit in either seat. ## A worked example Worked example: both players commit $100, so $200 sits in the middle. Over every board, ATs' average share is $136.76 (a gain of $36.76) and JTs' is $63.24 (a loss of $36.76). Think in thousands: about 675 of 1,000 go to ATs, about 308 go to JTs, and about 17 are chopped. ## The same matchup from the other side One page covers both views.

Take the 12 specific deals, group them by suit pattern, deal all 1,712,304 boards against each, and compare the two seven-card hands. Equity counts a tie as half a win; the flop rows use every one of a board's ten flops. Source: our own exact count from the GeorgeLiPoker poker math library.
