Dealt all in against each other, AJo takes 67.27% of the pot on average and JTs takes the other 32.73%. ## AJo against JTs: the numbers **Exact preflop results for AJo against JTs, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | AJo | 66.385 | 1.765 | 31.850 | 67.267 | | JTs | 31.850 | 1.765 | 66.385 | 32.733 | The first hand is an offsuit hand; the second is a suited hand. Sharing a rank is the signature of a dominated hand, since the weaker hand is usually out-kicked when the shared rank shows up. A lead of 34.54 points is large but not decisive: JTs still takes about 318 of every 1,000 deals. A split pot comes up on 1.77% of boards, so the wins and the equity differ by half of that. Among the 169 starting hands, AJo is number 15 and JTs is number 45 by strength against a random hand. **Boards behind the percentages: 61,642,944 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | AJo | 40,922,000 | 1,088,000 | 19,633,000 | | JTs | 19,633,000 | 1,088,000 | 40,922,000 | The total is exact: 36 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. **AJo 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) | | --- | --- | --- | --- | --- | | AJo | 2.055 | 1.506 | 3.140 | 0.487 | | JTs | 0.487 | 3.140 | 1.506 | 2.055 | The last column is the smallest pot odds, written as a pot-to-call ratio, at which a call breaks even with this equity. ## Who is ahead on which flops By flop texture, AJo's equity runs from 63.23% on monotone flops up to 76.03% on low rainbow flops (nine high or lower).

AJo does better with a shared suit, by 1.50 points. **AJo against JTs by suit overlap, in percent** | Deals | Specific deals | Share of deals | AJo wins | Ties | JTs wins | AJo equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 12 | 33.33 | 67.345 | 1.840 | 30.815 | 68.265 | | No shared suit | 24 | 66.67 | 65.904 | 1.728 | 32.368 | 66.768 | ## How often this matchup comes up Exactly 36 specific deals fit this matchup in one seat order, which is 0.0022% of 1,624,350; both orders together give 72, or 0.0044%. ## A worked example To see what the equity is worth, imagine $100 each in a $200 pot.
