AJs against A8s: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| AJs | 66.235 | 7.138 | 26.627 | 69.804 |
| A8s | 26.627 | 7.138 | 66.235 | 30.196 |
AJs meets A8s, and both are suited hands. 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.
AJs is well ahead, and A8s needs a specific kind of board to catch up. A split pot comes up on 7.14% of boards, so the wins and the equity differ by half of that.
For context, AJs sits at number 11 of 169 starting hands and A8s at number 21 when each is run against a random hand.
| Hand | Boards won, about | Boards tied, about | Boards lost, about |
|---|---|---|---|
| AJs | 13,610,000 | 1,467,000 | 5,471,000 |
| A8s | 5,471,000 | 1,467,000 | 13,610,000 |
Exact total: 12 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.
| Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) |
|---|---|---|---|---|
| AJs | 2.312 | 1.510 | 3.756 | 0.433 |
| A8s | 0.433 | 3.756 | 1.510 | 2.312 |
The last column is the break-even price: the pot odds a call needs to offer, as a ratio of pot to call.
Who is ahead on which flops
Across the five flop textures AJs' equity moves by 17.09 points, from 59.11% on low rainbow flops (nine high or lower) to 76.20% on rainbow flops topped by a ten or better. AJs stays ahead on all five textures, but the swing between them is large, so how the flop looks matters a great deal.
| Flop | Share of flops | AJs wins | Ties | A8s wins | AJs equity |
|---|---|---|---|---|---|
| Rainbow, ten or higher | 23.867 | 73.492 | 5.416 | 21.092 | 76.200 |
| Rainbow, nine or lower | 7.042 | 57.043 | 4.129 | 38.828 | 59.108 |
| Two-tone | 46.543 | 67.092 | 4.649 | 28.259 | 69.416 |
| Monotone | 5.215 | 60.679 | 6.271 | 33.050 | 63.815 |
| Paired | 17.333 | 59.351 | 17.674 | 22.975 | 68.188 |
Read the flop types this way: rainbow has three suits, two-tone has two cards of one suit, monotone has three, and paired repeats a rank.
