If TT and A8s get all the chips in before the flop, TT owns 68.17% of the pot in the long run and A8s owns 31.83%. ## TT against A8s: the numbers **Exact preflop results for TT against A8s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | TT | 67.981 | 0.371 | 31.648 | 68.166 | | A8s | 31.648 | 0.371 | 67.981 | 31.834 | One side is a pocket pair, the other is a suited hand. The pair is ahead of one card and behind the other, so the board decides how that plays out. A lead of 36.34 points is large but not decisive: A8s still takes about 316 of every 1,000 deals. Of every 100 boards, about 0.37 are split pots, and the equity figures already include them. TT ranks number 5 of 169 starting hands, and A8s ranks number 21, by equity against a random hand. **Boards behind the percentages: 41,095,296 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | TT | 27,937,000 | 152,000 | 13,006,000 | | A8s | 13,006,000 | 152,000 | 27,937,000 | The board total is exact, 24 deals at 1,712,304 boards each.

TT does better with a shared suit, by 0.56 points. **TT against A8s by suit overlap, in percent** | Deals | Specific deals | Share of deals | TT wins | Ties | A8s wins | TT equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 12 | 50.00 | 68.239 | 0.413 | 31.348 | 68.445 | | No shared suit | 12 | 50.00 | 67.723 | 0.329 | 31.948 | 67.887 | ## How often this matchup comes up The class pair covers 24 combinations of specific cards in a fixed seat order, 0.0015% of 1,624,350, and 48 (0.0030%) in either order. ## A worked example Take a $200 pot built from $100 each. TT's equity of 68.17% is worth $136.34, a $36.34 edge, and A8s' 31.83% is worth $63.66, which is $36.34 under its stake.

A tie counts as half a win in the equity column, and each board is counted once under each of its ten three-card flops. Source: our own exact count from the GeorgeLiPoker poker math library.
