Dealt all in against each other, AJs takes 62.62% of the pot on average and 75s takes the other 37.38%. ## AJs against 75s: the numbers **Exact preflop results for AJs against 75s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | AJs | 62.370 | 0.498 | 37.132 | 62.619 | | 75s | 37.132 | 0.498 | 62.370 | 37.381 | AJs meets 75s, and both are suited hands. With no overlap in ranks, every card that pairs one hand is a card that does not pair the other. A 25.24 point lead is real, and 75s still takes about 371 of every 1,000 deals outright. Ties are part of the picture: 0.50% of boards end in a split pot, and each side counts that as half a win. Place 11 of 169 belongs to AJs and place 124 belongs to 75s in the ranking against a random hand. **Boards behind the percentages: 27,396,864 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | AJs | 17,087,000 | 136,000 | 10,173,000 | | 75s | 10,173,000 | 136,000 | 17,087,000 | 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. **AJs against 75s read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | AJs | 1.675 | 1.603 | 2.693 | 0.597 | | 75s | 0.597 | 2.693 | 1.603 | 1.675 | 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 Break the boards down by their first three cards and AJs is strongest on rainbow flops topped by a ten or better (69.54%) and weakest on low rainbow flops (nine high or lower) (36.41%).
