A8s leads 56.16% to 43.84% before the flop, counted exactly over every board, with the split by flop type and suit. Before any board card is dealt, A8s holds 56.16% equity against QTs, which leaves QTs with 43.84%. ## A8s against QTs: the numbers **Exact preflop results for A8s against QTs, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | A8s | 55.918 | 0.478 | 43.604 | 56.157 | | QTs | 43.604 | 0.478 | 55.918 | 43.843 | A8s and QTs are both suited hands. The two hands share no rank, which makes this a pure matchup of card strength, straight chances and flush chances. A 12.32 point lead is real, and QTs still takes about 436 of every 1,000 deals outright. About 0.48% of boards chop the pot, which is why equity sits slightly above the win figure for both hands. Ranked by equity against a random hand, A8s is number 21 of the 169 starting hands and QTs is number 34. **Boards behind the percentages: 27,396,864 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | A8s | 15,320,000 | 131,000 | 11,946,000 | | QTs | 11,946,000 | 131,000 | 15,320,000 | Exact total: 16 deals times 1,712,304 boards. The other three counts come from the five-decimal percentages and are rounded to the nearest thousand, so read them as approximate. **A8s against QTs read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | A8s | 1.281 | 1.788 | 2.293 | 0.781 | | QTs | 0.781 | 2.293 | 1.788 | 1.281 | 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 A8s prefers low rainbow flops (nine high or lower), where it holds 72.57%, and likes rainbow flops topped by a ten or better least, where it holds 50.23%.
