The exact count puts A5s at 70.69% and 53s at 29.31% when the two hands see all five board cards. ## A5s against 53s: the numbers **Exact preflop results for A5s against 53s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | A5s | 69.427 | 2.532 | 28.041 | 70.693 | | 53s | 28.041 | 2.532 | 69.427 | 29.307 | Each side holds one of the suited hands: A5s and 53s. Because the hands share one rank, the one with the higher kicker is ahead when that rank pairs and the other hand is mostly drawing. A5s is well ahead, and 53s needs a specific kind of board to catch up. 2.53% of boards are ties, so the equity of each hand is its win rate plus half of that. For context, A5s sits at number 30 of 169 starting hands and 53s at number 146 when each is run against a random hand. **Boards behind the percentages: 20,547,648 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | A5s | 14,266,000 | 520,000 | 5,762,000 | | 53s | 5,762,000 | 520,000 | 14,266,000 | 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. **A5s against 53s read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | A5s | 2.412 | 1.440 | 3.566 | 0.415 | | 53s | 0.415 | 3.566 | 1.440 | 2.412 | 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 The flop changes the picture. A5s does best on paired flops, at 75.42%, and worst on low rainbow flops (nine high or lower), at 57.70%.
