The exact count puts AJo at 68.77% and QJs at 31.23% when the two hands see all five board cards. ## AJo against QJs: the numbers **Exact preflop results for AJo against QJs, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | AJo | 68.049 | 1.437 | 30.514 | 68.768 | | QJs | 30.514 | 1.437 | 68.049 | 31.232 | The first hand is an offsuit hand; the second is a suited hand. The two hands share a rank, and the one with the better other card dominates: it wins most kicker battles when that shared rank hits. That is a clear edge, 68.77% to 31.23%, but QJs still wins often enough that one hand proves nothing. About 1.44% of boards chop the pot, which is why equity sits slightly above the win figure for both hands. The hand ranking puts AJo at 15 and QJs at 28 out of 169 starting hands. **Boards behind the percentages: 61,642,944 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | AJo | 41,947,000 | 886,000 | 18,810,000 | | QJs | 18,810,000 | 886,000 | 41,947,000 | 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 QJs 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 | 2.202 | 1.470 | 3.277 | 0.454 | | QJs | 0.454 | 3.277 | 1.470 | 2.202 | 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 Low rainbow flops (nine high or lower) are the best for AJo (81.38%); monotone flops are the worst (64.32%).
