If AKo and JTo get all the chips in before the flop, AKo owns 63.12% of the pot in the long run and JTo owns 36.88%. ## AKo against JTo: the numbers **Exact preflop results for AKo against JTo, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | AKo | 62.899 | 0.445 | 36.656 | 63.122 | | JTo | 36.656 | 0.445 | 62.899 | 36.878 | This is a contest between two offsuit hands, AKo and JTo. Neither hand shares a rank with the other, so this is a contest of high cards, connection and suits. AKo is ahead, but JTo is far from dead: it takes 367 of every 1,000 deals outright. About 0.45% of boards chop the pot, which is why equity sits slightly above the win figure for both hands. Place 12 of 169 belongs to AKo and place 57 belongs to JTo in the ranking against a random hand. **Boards behind the percentages: 246,571,776 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | AKo | 155,091,000 | 1,097,000 | 90,383,000 | | JTo | 90,383,000 | 1,097,000 | 155,091,000 | 144 specific deals times 1,712,304 boards gives the exact total.

AKo does better with a shared suit, by 0.61 points. **AKo against JTo by suit overlap, in percent** | Deals | Specific deals | Share of deals | AKo wins | Ties | JTo wins | AKo equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 120 | 83.33 | 62.994 | 0.460 | 36.546 | 63.224 | | No shared suit | 24 | 16.67 | 62.428 | 0.365 | 37.207 | 62.611 | ## How often this matchup comes up You will meet this exact matchup 0.0177% of the time in a random heads-up deal: 288 of 1,624,350, counting either seat order. ## A worked example A $100 all-in from each player makes a $200 pot, and the exact equity says AKo gets $126.24 of it on average and JTo gets $73.76.

Take the 144 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.
